The Cryofuge 6000i is an attractively
designed, large volume floor standing
refrigerated centrifuge by Kendro
Laboratory Products offering
optimised technology for lowspeed
applications.
It is ideal for use in blood banks, biotech-
nology and the pharmaceutical industry,
where large volumes are centrifuged at
high speeds and constant temperatures.
It is also used for routine separation tasks
in laboratories and production facilities.
The use of sophisticated microelectronics
systems and high strength materials for
rotors and accessories guarantees out-
standing reproducibility and highly
accurate centrifugation.
With a large 6 litre capacity and a top
speed of 4240 rpm (6010 x g), the
Cryofuge 6000i is designed for a wide
range of separation tasks. It can accom-
modate 1.5 ml tubes, 1 litre containers
and quad blood bags.
The Cryofuge 6000i is competitively
priced and comes with a wind-shielded
rotor and an extensive range of accesso-
ries. Back up from an international
support and service organisation ensures
maximum performance and reliability.
Typical applications
The Cryofuge is designed, in particular,
for the qualified production of human
blood components in blood banks. It is
also used for blood fractionation, serumextraction, radio immuno assays (RIA),
cell preparation, fractionating protein and
enzyme precipitates, separating fine crystal
deposits and in fact, in every situation
where high performance and capacity are
required.
Powerful technology
The Cryofuge is equipped with a power-
ful, maintenance free induction drive for
quiet and smooth operation. Its refri-
geration system uses the environmentally
friendly CFC free refrigerant R 404a.
Acceleration and braking times have
been optimised for all application require-
ments. An automatic digital temperature
compensation system prevents samples
from freezing.
User friendly
A new automatic lid lock enables the
Cryofuge to be closed easily. The ergo-
nomically designed keypad allows simple
entry and storage of operating para-
meters. Main control functions areconveniently arranged for easy access,
while the SEPACONTROL control system
makes operation straightforward. The
"delay" function permits users to delay
system start-up.
Microprocessor control
The Cryofuge is equipped with 33 centri-
fugation programs for routine applications.
Nine acceleration and nine braking profiles
ensure reproducibility of all centrifugation
parameters. The Cryofuge is now also
equipped with a profile program fordefining up to 10 cut-off points with time,
speed, braking and acceleration curves.
Speed is controlled digitally with auto-
matic RCF adjustment. Centrifuges can
also be connected to a computer for
data recording via a serial interface.
Safety
When designing the Cryofuge, all inter-
national safety standards were kept in
mind to guarantee the highest level of
safety. Diagnostic and fault messages are
clearly visible. Pre-selection of buckets
protects against overspeeding. The lid
lock system and steel armoured rotor
chamber further ensure safe operation.
A key operated switch safeguards
against unauthorised use.
Service friendly
The Cryofuge is equipped with a digital
self diagnosis system for monitoring
operability. If a fault is detected, a mes-
sage is immediately displayed. Should
an error occur, however, our fast and
efficient international service team can be
relied upon.
The Cryofuge 6000i Refrigerated
Centrifuge is used for the qualified
production of human blood
components in blood banking.

Wind-shielded rotor and lid, showing a selection of the extensive range of buckets and
adaptors.
CRYOFUGE6000i GMPAND 8500i GMP
Convenient operation
The SEPACONTROL operating panel is
systematically arranged, clearly displays
all functional areas and permits easy
access to operating parameters. The
user simply presses a few keys to select
the required centrifugation program and
start the Cryofuge. A design which
eliminates knobs and dials ensures highreproducibility and easy cleaning of the
control panel.
SEPACONTROL provides users with
up-to-date information on the status of
the system. Visual diagnostic indicators
and acoustic signals supplement the
information supplied by the microcom-
puter. This makes it easy to use the
centrifuge right from the start.
Key operated switch
This switch protects programs againstunauthorised access. Depending on the
position of the switch, users are either
permitted to freely program the system,
call up one of the 33 programs in
memory or simply repeat the program
last used.
Panel
Five visual displays facilitate the identifi-
cation of problems during centrifugation.
When the lid is opened (check lid), the
rotor is unevenly balanced (imbalance),
in the event of a system error (system
check), programming error (progr. error)
or if the temperature limit has been
exceeded (overtemp), an LED signals a
warning.
Memory control
33 memory locations are available to
save run parameters for future use. New
programs generated using the function
panel can be immediately added to the
library.
Status
The status field is systematically arranged
into the following areas: start-up and
braking curves, speed and rotor data,
time and temperature. LEDs prevent the
user from confusing the values on the
display.
Programming
The programming field permits easy
setting of the required parameters. Only
5 keys are required for completely pro-
gramming all parameters! The keys are
used for changing the display setting,
values displayed and confirming input.
Simple, functional operationThe basic functions for opening the
centrifuge lid, starting and stopping the
system and quick-stop are located on
the front of the Cryofuge for immediate
access.
Rotor and accessories
An aerodynamic wind-shielded rotor and
6 different types of bucket ensure maxi-
mum performance and flexibility. The wind-
shielded rotor is included in the basic
centrifuge package. The vast range of
accessories is listed in the tables overleaf.
Four buckets have been specially devel-
oped for centrifuging blood and pro-
ducing thrombocyte concentrates. The
system can handle all standard blood
pack systems. Additional accessories
such as plastic inserts and balancing
accessories round off the package.
Two other buckets used in combination
with various adaptors permit all tubes
with nominal volumes between 1.5 ml
and 1000 ml to be centrifuged.
HERANET data documentation
The Heraeus HERANET data documen-
tation system is available for data
documentation in accordance with GMP.
Please request our HERANET brochure
from your Kendro representative.
The Cryofuge 6000i GMP (Good Manu-
facturing Practice) offers the same perfor-
mance and accessories as the Cryofuge
6000i. The Cryofuge 8500i GMP attains a
maximum centrifugal force of 8525 x g
and a maximum speed of 5050 rpm.
GMP Cryofuges are specially designed for
use in clean room applications.
Special features of the Cryofuge
6000i GMP and 8500i GMP
The special encapsulated casing is sealed
to prevent particles from escaping and
contaminating the clean room. The space
between the centrifuge and floor is equip-
ped with a rubber gasket. Thanks to its
special smooth finish, the casing is very
easy to clean. The 6000i GMP and 8500i
GMP are equipped with connections for
an external cooling water system; the flow
rate of the cooling water is kept to a mini-
mum. On request, the system can be
connected to an external cooling system.
The enclosed and sealed casing and
vibration insulation system ensure low
noise generation during operation. Heat
radiation is also minimised.

s Dual processing control before
and after centrifugation
GMP: The centrifuge and applications
The new HERANETsystem is the result of
ongoing improvements to a centrifuge in
accordance with GMP. The Heraeus
Cryofuges 6000i/8500i, two large volume
refrigerated centrifuges with a capacity of
6 x 1 litres or 12 quintuple blood bags, are
the first centrifuges on the market offering
a complete documentation system.
The Cryofuges are used in general biotech-
nology and for production purposes, for the
sedimentation of cells and other crystalline
materials. However, the most frequent
application is the isolation of blood com-
ponents from blood, in blood banks and
blood donor centres. Continuous monito-
ring of processing data through automatic
data capture. Business sectors producing
in accordance with GMP (Good Manu-
facturing Practice), increasingly demand
centrifuges which comply with GMP. For
a number of years Heraeus has been
offering a special version of the Cryofuge,
the Cryofuge GMP.
Features of the
Cryofuge 6000i/8500i GMP
The Cryofuge 6000i/8500i GMP offers
some special design features:
sThe special encapsulated casing is
sealed to prevent particles from escaping.
The space between the centrifuge and the
floor is equipped with a rubber gasket.
sThe casings special lacquered finish
makes it easy to clean.
sA connection to an external water
cooling system ensures that a minimum of
heat is emitted to the environment.
s Due to the enclosed and sealed casing,
with its vibration insulation system, very
little noise is generated during operation.
s On request, the system can be connec-
ted to an external cooling system.
Heraeus HERANET system
HERANETprovides a complete overview
of all data arising during the centrifugation
process. Up to 30 centrifuges can be
managed with HERANETvia one PC. Each
centrifuge can be equipped with one of
three different barcode readers (pen,
contact or laser) for additional input of
process data like user ID or blood bag ID.
HERANET DOCUMENTATION OF CENTRIFUGE
DATA IN ACCORDANCE WITH GMP
Continuous monitoring of processing data
through automatic data capture.
The worlds first: HERANET data documentation system in accordance with GMP
Kendro Laboratory Products has developed a system for centrifuge data documentation,
in cooperation with hospitals and blood banks. For the first time ever, it is now possible
to constantly monitor all processing data arising during the production of blood compo-
nents. Additionally, this system is suitable for all hospital and industrial sectors which
have to provide processing data documentation in accordance with GMP.

HERANEToffersmaximum flexibility anddue
to its standardised transmission protocol it
is also a viable option for the future.
Data administration is performed on a
Windows compatible PC. The data is
recorded and displayed using a specially
developed Windows software.
Monitoring with HERANET
With the help of a programmed value
editor, production controls can be defined
by setting tolerance limits for centrifugation
speed and temperature, in addition to
programmed values. Additionally, the
maximum time from the closing of the lid
to the starting of the centrifuge, and from
the finishing of the run to the opening of
the lid, are specified.
Following operation, it is automatically
checked that none of the recorded values
exceeded the defined tolerance limits.
In this case, the run is classified as being
OK and the actual data records can be
deleted according to the configuration of
HERANET. The processing data and the
programmed values are saved, including
the permissible tolerances.
Once compressed, the data records of
the centrifugation can be archived on a
mainframe computer, which collects all
blood bank processing data.

2. SERVICE2.1 Servicing Schedule (Yearly Procedure)
2.1.1 Maintenance Routine without Dismantling the Centrifuge
1. Electrical Installation and SafetySwitch OFF the centrifuge and disconnect the unit from power.Check voltage supply and mains fusing (3 x 32 Amps slow blown characteristic or other forcorresponding line voltages)Check condition of plug and wall socket - replace defective parts.Check main contactor for burnt out poles.Check cord condition and fixing - replace or refit it.
2. Location and Mechanical InstallationCheck the base for resonance-free and stable conditions.Check for a well ventilated place and sufficient distances to walls or adjacent equipment (min.30 cm, rear 50 cm), avoid direct sunlight.Check the levelling of the centrifuge - use a spirit level. Watch correct position of the floorsealing, if necessary use silicone for additional sealing
3. Lid Locking Mechanism and Safety DeviceConnect the centrifuge to power and switch ONMake sure that there is water-flow to the unitCheck for easy lid closing and self-acting lid opening - if in disorder, re-adjust lid looped hooksand/or move lid lock assembly aside and smear hooks slightly with grease.Check the central rubber gasket for lid sealing and replace it, if damaged.Open the lid and turn the rotor by hand, then close the lid and try to open it using the lid key: thelid must not be opened as long as the speed values (> 10 rpm) are indicated - if safety circuit isout of function, replace main board.
4. Cleanliness of Spin Chamber and Motor CoverOpen the lid and remove the rotor: for loosening turn rotor's collar nut by use of 19 mm fixedspanner anti clock wise (in arrow direction - see rim of rotor bowl), thereby hold the rotor on it'scross.There is an additionally turn resistance after approx. one revolution which has to be overcomewith an further lever pressure of the fixed spanner. Then turn the drive shaft clockwise with the10 mm socket wrench as long as the rotor can be lifted up. Two persons are necessary to seizethe rotor by it arms on opposite and to lift the rotor carefully out of the bowl.Clean the wind-shield with a dry and absorbent cloth (remove all dust and moisture - see alsoCleaning section in operating instruction)Check the correct seat and condition of the motor cover.Take care of the cleanliness of the annular slot around the motor shaft: there is shaft packing offelt which has to be soaked with oil. Penetrating fluids can damage the upper motor bearing.
5. Rotor and Bucket Condition and SealingCheck the condition of rotor and buckets (especially all supporting or stressed partitions as jibarms, rim of the bucket's bearing surface etc.): the rotor and/or buckets must not be used anylonger, if there are visible traces of mechanical damage or rust.Check the condition of rotor and/or bucket sealing and replace them in case of malfunction
Advise customer to clean and grease trunnions once a week.
6. Rotor Fixing and Motor ShaftCheck the condition of the drive motor shaft: the centrifuge must not be used any longer, if thedrive shaft is damaged (bend, thread is worn out, horizontal grooves etc.)

7. Temperature Control CircuitCheck water trough-putCheck the thermal isolated fixing of the temperature sensor.Re-install the rotor and run the centrifuge at 2000 rpm (1500 rpm with buckets 75007719) and at4CCheck the temperature 60 minutes later: the displayed and measured value should be
approximately the same (tolerances +/-2K)
8. Water circulationCheck water valve settings. The valve is factory set to 3,7. Due to different water pressure at thecustomers it could be possible that there is an additional adjustment necessary. A reduction ofthe setting will increment the water through-put. A counter pressure at the out-put hose will cutoff the unit by the high pressure control switch.
9. ThermostatThe thermostat is factory set to 27,5 C +/- 3,5K and should not be de-adjusted.
2.1.2 Maintenance Routine after Dismantling the Centrifuge Casing (see Section 5)
1. Motor Supporting ElementsCheck the supporting and damping motor elements (enlarged rubber abrasion, often imbalanceruns) and replace them by worse condition or at least every 3 years.Watch the charge of the rubber mounts and install all three with the same number.We recommend to change the red rubber flange as well every three years.
2. Imbalance SwitchCheck the function of the imbalance switch and replace in case of malfunction.(see also 2.4 Adjustment of Imbalance Switch)
3. Braking Circuit
Check the function of the braking circuit (warming up of brake resistor, even and noiselessbrake effect) and replace defective parts in case of malfunction.
4. Lead and Screwing Connections*Check the terminal and plug connections of leads on all boards and electrical components,replace defective parts.*Check the screwing connections of boards, mechanical and electrical components and tightenthem if necessary.
5. Protection Earth Core and Grounding Connections*Check the protection earth core for continuity and all grounding plug connectors*Check insulation resistance and measure the substitutional leakage current (see 2.6 ElectricalSafety Check)
6. Water connection
*Check the watertightness of all connections and hoses*Disconnect the outlet hose and let the water run into a bucket. Check the flow rate within oneminute. A this test the compressor must run.

2.4 Adjustment of Imbalance Switch
2.4.1 Meaning of Imbalance Switch
The imbalance switch has the task to switch off the centrifuge by incorrect loading of the rotor beforereaching the normal speed.
NOTE!1) Before starting with the re-adjustment procedure check the greasing of rotor trunnions andcleanliness of bucket groves. Opposing buckets and racks must be identical and equal inweight.
2) Check the motor's rubber mounts and the levelling of the drive with installed rotor (use aspirit level).
2.4.2 Adjusting Procedure
Tools and accessories:
Rotor 75006606 with buckets 75008078
check weights: 40g + 80g
Procedure
Disconnect unit from power and open the front door.
Loosen both M6 screws on bottom of mounting angle of imbalance switch to keep it movable.
Pull imbalance assembly away from the drive.
Move the assembly very slowly in direction to the drive until a clicking noise is audible.
Refix both screws and start the test run.
2.4.3 Test Run Performance
Install the rotor 75006606 with all buckets 75008078.
Load one bucket with the check weight of 80g.
Close the lid, select acceleration curve 9 and then press the start key.
The imbalance message "bal" must appear when passing 1400 rpm.
If no imbalance signal occurs, correct the adjustment by pulling the assembly a little away fromthe drive.
Exchange now the 40g weight and repeat the procedure.
The rotor must reach the max. programmed speed without imbalance signal
NOTE!
Both imbalance tests (with 40 and 80 grams) must be performed with in the buckets 1, 3 and 5 thatmeans 6 test runs are necessary.

*Speed detection board is mounted underneath the drive motor.
*Imbalance switch S6 mounted aside and in front of the drive motor (for adjustment seesection 2 page 2-9).
*Two lid lock assemblies each with motor locking system and integrated micro switches (S2,S3 and S4, S5).
*Temperature sensor V1 (PT100).
*Driving stage for compressor contactor K3 (cuts in compressor M2).
*Heating element as brake resistor R1 with integrated fan M6 (mounted behind the casing'sback panel).
*A fan (M5) for power electronics on main board
*Heat-exchanger with fan and thermostat
Deviating to the standard model (built-in compressor) the unit for external compressor systemmay not have all described parts.
For controlling of the external compressor the unit offers three phases 16 A protected to powerthe compressor directly. In case of an external contactor this can also be controlled by phaseand neutral from internal contactor.
The external high pressure control switch will give the feedback via connector XO.
Because of sometimes very long distances between the compressor and the centrifuge it couldhappen that the temperature will overshoot. To prevent this a magnetic valve will be openedand closed parallel with the compressor contactor

3.3.2 Intermediate Circuit with Brake Path and Frequency Converter
The DC intermediate circuit serves as an energy store between the AC power input and thetransmitted motor performance.The intermediate circuit consists of a bridge rectifier and 12 parallel connected reservoir capacitorswhich are softly charged at the beginning over heavy-duty resistors (R61 and R110 parallelconnected). When the capacitor's loading has reached the defined value, the resistors arebypassed by the relay K1 to supply frequency converter with maximum main power duringoperation.
Brake PathElectrical power is fed back into the intermediate circuit during motor deceleration (motor acts asgenerator). This braking power is transformed into heat by brake resistor R1 (terminal XD) so thatthe intermediate circuit voltage does not rise to an excessive level (see section 2 - test points onmain board).The brake resistor R1 is switched into the intermediate circuit by a fast switching transistor. This
transistor is voltage dependent controlled by a self-acting stage (closed loop).
Frequency ConverterThe motor is 3-phased provided with chopped direct voltage blocks. These blocks are variable infrequency and pulse width modulation and are dephased to 120 between the motor windings.Beginning with low frequency and small pulse width chopped blocks, both parameters will beincreased up to the operators set speed. By this variation the acceleration power of the drive motorcan be effected. For deceleration the frequency and pulse width parameters will be reduced. Thefrequency converter is dynamically and absolutely protected against overcurrent and overvoltageand also absolutely protected against excessive temperature.When exceeding one of the absolute values (overcurrent, overvoltage or excessive temperature),the message "Err.08" will be displayed.
3.3.3 Microcontroller (Central Processing Unit)
The controller block includes the central processor unit (CPU) P87C51FC and two of the datastorage (NV-RAMs) 93S66 with the software identification No's. for:
*CPU: 0599 (second displayed No. in speed field)*1. NV-RAM: 7571 (third displayed No. in speed field) in CF 6000i only*1. NV-RAM: 7572 (third displayed No. in speed field) in CF 8500i only*2. NV-RAM: 7573 (fourth displayed No. in speed field)
The second parts of these No.'s (displayed in the time field) will be upgraded if necessary.The ROM with control program is integrated in the CPU. The most important operating parameters(e.g. the maximum data or the last operator settings) are stored in the non volatile (NV) -RAM.The CPU co-operates with the ASIC 80 component via the 8 bit data bus and some control lines.
The ASIC 80 is a specially designed integrated circuit for the driving of Kendro centrifuges (withinduction motors), containing additional functions for speed and temperature measuring andelectronics protection.

3.3.4 Latch Control-system
The mainboard allows a controlling of the new electrical latch system with current software (CPU599) and controlling of the old mechanical latch with old software (CPU 498) as well.
Note! The new Software does not control the old latch system.
Electrical latchBoth latches are connected to the board via terminal XC1 and XC2.Each latch will be driven forward and backward via a relay by a special driver IC which changes thepolarity of the voltage depending on status of the wanted operation - open or close the door.The activating of the door latches is several times protected by addition status controls of the CPU.The door can only be opened if the speed is 0 and the lid opening button was pushed.
Mechanical latchThese mechanical latches are connected at the terminal XC. They are controlled by a triac which isfired via photodiac by CPU. Two tachogenator signal trigged flip-flops prevent an opening of the
door whilst rotor is spinning.
3.3.5 Temperature measurement
The temperature will be detected by a PT 100 temperature sensor.Two reference resistors 100 ohm = 0C and 120 ohm = 50C will give the reference value. Theauto-calibration is done by the CPU which controls an analogue switch where the signals will betransferred to a voltage/frequency converter. This select signals to the switch IC will come from the
ASIC TEMP_0 and TEMP_1.
3.4 Key and Indication Board
The SEPACONTROL key and indication board is mounted behind the operational panel.
A special microcontroller (P87C51FC) is located on this board controlling the 7 segment displays,the control key LEDs and the operating keysThe communication with the central processor on the main board takes place via serial data lines inboth directions (plug XI).The reading of the keys and the displaying of values takes place by multiplex operation. Alloperational parameters and user programs are stored unlimited in 6 NV-RAMs (type 93C46).The constant identification No. of the key board processor is 0497 (first displayed No. in speedfield). There is a second No. displayed in the time field at the same time. This version No. is subjectof the permanently technical outgrowth and will be counted up at any program changes on CPU orparameter changes on NV-RAMs.
3.5 Speed Detection Board
The speed detection takes place opto-electronically through a slit in the motor shaft.A light-emitting infrared diode and a photo-transistor are mounted on the speed detection boardand located on opposing sides of the motor shaftSo 2 trapezoidal pulses per motor revolution are generated and transformed into stable rectanglepulses (Schmitt trigger circuit on board), by which the micro controller calculates the real rotorspeed or rcf value.The speed detection board is connected to the main board via the 3-pin plug XW.

3.6 Imbalance switch
If abnormal imbalance of the rotor occurs the imbalance switch will be triggered by the movingmotor. The switch closes and this signal will be given to the CPU which detects this as
imbalance
The connection to the switch is made of 4-pole wiring which allows a check of the cable fordefect. In this case the imbalance signal will also be displayed.
3.7 Cooling plant
The Cryofuge is equipped with a high-grade cooling plant, to meet its requirements of drivingpower and compact design. The CFC free refrigerant R404A evaporates at low temperatures
( -20C) and absorbs through this the frictional heat from chamber produced by the spinningrotor. Instead of an air-cooled condenser the GMP version is equipped with a water-cooledtube-within-a-tube heat-exchanger which keeps the refrigerants condensing temperature on a
low level.
The condenser serves for essential under-cooling of the condensed refrigerant to ensure anoptimum evaporation and a perfect operation of the expansion valve. To maintain lowevaporation and resultant condensation temperatures on one hand and to support the startingprocedure of the compressor on other hand, a thermostatic expansion valve is used.
In this model, the outer tube contains refrigerant and the inner tube contains water. The twofluids flow in opposite directions so the incoming, cold water contacts the refrigerant that is justabout to flow to the receiver. This ensures the greatest temperature reduction in the refrigerant.Depending on the compressor cycle (on or off) a pressure controlled water valve opens or closesthe flow through the heat-exchanger. When compressor is deactivated there is no water-flowthrough the system.
A parallel installed heat-exchanger for controlling of the ambient of the motor will also bepassed by the water. This is controlled by a thermostat to 27C which activates a fan and amagnetic valve.
The minimum achievable sample temperatures are depending on speed, rotor type and a littleon ambient temperature. After a compensating time (at max speed 3 hours) as optimal result,
the rotor has reached the selected set temperature within a tolerance of 2K. The compressorsystem is powerful to cool down the rotor about 6K/h at maximum speed.
In case of water interruption and running compressor the pressure of the refrigerant will rise andthe HPCS will cut off the centrifuge. After return of the water the unit will be automatically reset.In case of counter pressure at the outlet so that the needed pressure difference had fallen below
the unit will also cut off.
3.7.1 External Cooling Plant
Units with external compressor system will offer the needed voltage for a three phase
compressor or 230 V AC to control an external installed compressor contactor. A parallelinstalled internal magnetic valve controls the flow of the refrigerant and prevents an over-shooting of the temperature.
An external installed high pressure control switch (HPCS) is wired to the internal terminal box ofthe unit.

The external cooling plant is not part of the unit and has to be installed by the customer. Foradditional information Kendro service will assist.
For external cooling plant a water cooled or an air cooled compressor system can be used. When
using air-cooled system nevertheless the centrifuge requires water for the internal heat-exchanger.
When developing the external cooling plant please note the following:
- Heat rejection approx. 13,320 kJ/h (CF 6000i) 17,600 kJ/h (CF 8500i) must be carried- Only materials (Copper pipes, fittings, etc.) suitable for cooling plants are allowed- Depending on the distance between compressor and centrifuge calculate the size of thepipes to reduce pressure drop. We recommend minimum 16 mm of suction and 10 mm ofhigh side.
