Further Evolution of High-accuracy Temperature Control Achieve high energy-saving performance

Achieve low-noise operation in the low-load range

Expansion of cooling capacity control range

RoHS Compliant

Compact design of top class in the industry

■Our acclaimed ±0.1℃ oil temperature control has been extended to cover an even wider range.

■The cooling capacity resolution in the low-load range has been improved through optimal control of the compressor and electronic expansion valve.

■Control with loads from 0% (no load) to 100% achieved

No load

Outlet oil temperature control

■Complies with the RoHS Directive, e.g. by adopting printed circuit boards with lead-free solder.

■Achieve high energy-saving performance with the adoption of a Daikin original IPM motor and R410A refrigerant for high COP characteristics.

■The power consumption can be checked on the operation panel.

Power consumption (*1)

59.5dB（A）　 58dB（A）Corresponding value in anechoic chamber (with AKZ 439 class)

■Noise level also reduced in line with load reduction*At room temperature of 25 and thermal load of 1 kW

■Refrigerant gas leakage detection alarm functionAn alarm signal is output when the refrigerant gas would be leaked (as cooling circuit failure).

■Oil temperature warning functionA warning signal can be output when the oil temperature or air temperature strays outside arbitrarily setting range.

■Auto tuning functionThis function substantially cuts the time taken for adjustment during trial operation by automatically setting the gain when oil temperature control is not stable in the factory setting status or when optimization is required.

■999-hour timer function (ON timer)The operation start time can be set from 0 to 999 hours in one-hour units.

■Preventive maintenance function●A warning signal is output to notify that maintenance is required when the air filter or condenser becomes clogged.

●If the thermistor fails (out of control), emergency operation is possible by selecting another operation mode. This function minimizes the factors of line stoppages.

■The control panel has been revamped. Data is now displayed in an easier-to-understand format with more digits space.

The power consumption is also displayed (new function).■The newly adopted plug-in terminal block has enabled tool-less connection of signal cables (simple connection).

■The increased pitch of the condenser’s fins suppresses clogging and makes cleaning easier.

【Refrigerating cycle】A：Refrigerant gas is converted into compressed gas at high temperature and high pressure by a compressor so that gas can be easily cooled and liquefied by a condenser.B：In the condenser, the gas at high temperature and high pressure made in the compressor is cooled with air and converted into liquid at high temperature and high pressure.C：The pressure reduction mechanism reduces the pressure of the liquid at high temperature and high pressure and converts it into liquid at low temperature and low pressure 　 by squeezing it so that it can be easily evaporated in a cooler.D：In the cooler, liquid at low temperature and low pressure made in the pressure reduction mechanism removes heat from oil, evaporates （cools oil）, 　 and is converted into gas at low temperature and low pressure.E：The bypass mechanism controls the cooling capacity at low loads by adjusting the volume of gas at high temperature and high pressure supplied to the cooler.

Note）*1. The cooling capacity represents the value at the standard point（inlet oil temperature: 35℃, room temperature: 35℃, oil for use: ISO VG32）. The tolerance of the product is approx.±5%.*2. Be sure to use a commercial power supply for the power source. The use of an inverter power supply may cause burn damage to the unit. The voltage fluctuation range should be within ±10%. If the voltage fluctuation range is more than ±10%, please consult us. *3. There are three types of different voltage specifications depending on the power source: －046, －047 and －048 units. －047 and －048 units deal with the different voltage by featuring a transformer. The main circuit voltage is the transformer’s secondary side voltage of 200 VAC, 50/60 Hz. (－046 units have no transformer and therefore have the same external dimensions and mass as standard units. Their main circuit voltage is 220/230 VAC, 50/60 Hz.)*4. The machine temperature synchronous thermistor optionally available is required for this function.（Refer to Page 19 for details.）*5. The MSDS（Material Safety Data Sheet） of refrigerant R410A is attached to ーC type.*6. Electric component box ingress protection: IP54 or equivalent (However, use piping conduits etc. rated at least IP54 at wiring ports.)*7. The specifications for withstanding vibration during transport are those of a standard unit.*8. The molded-case circuit breaker is not supplied with this product. Please prepare it by yourself.*9. The yellow line on the tank oil level gauge shows the highest oil level and the red line the lowest oil level.*10.

Notes for installing external piping

Notes for installing external piping

If the external pressure loss （site piping resistance） exceeds the specified use range, there may occur phenomena such as abnormal noise of the pump （relief noise, noise of cavitation）, decrease of cooling capacity and control failure of oil temperature. Keep the external pressure loss within the specified use range.

1. Suction-side pipingKeep the suction vacuum pressure within the range between -30.7 and 0kPa.The use of a suction filter of 100 to 150 mesh is recommended.

2. Discharge-side piping Keep the pressure loss of the discharge-side piping at 0.5 MPa or less.3. Do not install a stop valve on the suction or discharge side. When a stop valve must be installed on the discharge side out of necessity, use a 0.5Mpa relief valve along with the stop valve.

4. Calculation of piping resistanceDetermine the oil piping size by calculating the piping resistance according to the following equation:

Piping resistance △P=0.595 ×ν×Q×L/Ｄ4（For use of general hydraulic oil and lubricant）

Piping resistance（MPa）Dynamic coefficient of viscosity（mm2/s）－Refer to the Viscosity / Temperature Chart.Flow rate （L/min）Piping length （m）Internal piping diameter （mm）

△ P ：ν ：

Q ：L ：D ：

Design the site piping to withstand a pressure of at least 1.0 MPa.Note）

●Relationship between oil flow rate and external pressure loss

An AKZ 9 series Oil Cooling Unit incorporating a pump of the circulation type has the characteristics shown below. When the external pressure loss (△p) is 0.5 MPa or less, the rated flow rate (Q0) is achieved, but when the external pressure loss exceeds 0.5 MPa, the flow rate becomes lower than the rated flow rate.

Good exampleBad example

△P ＞0.5MPa↓

The oil flow rate becomes Q1, lower

than the rated flow rate.

△P ≦0.5MPa↓

The rated flow rate （Q0） is achieved.

Unit conversion formula ●1kW＝860kcal/h

1.Select Oil Cooling Unit having a cooling capacity 20 to 30% larger than the heat release value from the machine tool.2.Since the cooling capacity of Oil Cooling Unit varies with the change of liquid temperature （inlet liquid temperature） and room temperature, it is necessary to clarify the liquid temperature and room temperature conditions to select appropriate Oil Cooling Unit.3.Three methods are shown below as a guide for estimating the heat release value from the machine tool. For determining the heat release value eventually, it is necessary to conduct tests and determine the exact heat release value for selecting appropriate Oil Cooling Unit.

●Calculation method of heat release value from main machine 　for the selection of appropriate Oil Cooling Unit （as a general guide）In the case of cooling of main shaft of machining center

1.Select Oil Cooling Unit having a cooling capacity 20 to 30% larger than the heat release value from the machine tool.2.Since the cooling capacity of Oil Cooling Unit varies with the change of liquid temperature （inlet liquid temperature） and room temperature, it is necessary to clarify the liquid temperature and room temperature conditions to select appropriate Oil Cooling Unit.3.Three methods are shown below as a guide for estimating the heat release value from the machine tool. For determining the heat release value eventually, it is necessary to conduct tests and determine the exact heat release value for selecting appropriate Oil Cooling Unit.

●Method 1: To estimate the heat release value from the temperature difference between the supply oil and return oil

Heat release value（kW）Constant pressure specific heat（Ｊ/kg℃）・・・1967.4Ｊ/kg℃Weight volume ratio（kg/m3）・・・876kg/m3

Oil flow rate（m3/h）Temperature difference（℃）・・・T2ーT1

E.g.） When “Vs” is 18m3/h（30L/min） and “△T” is 5℃　 Q＝2.778×10-7×1967.4×876×1.8×5　　　　　＝0.479×1.8×5≒4.3kW

●Method 2: To estimate the heat release value from the increase rate of oil temperature in the tank

Find the maximum gradient of oil temperature increaseTo find the maximum gradient of the oil temperature, it is necessary to measure △t every one minute during the first 10 minutes.

E.g.） When the total oil quantity is 300L （0.3m3） and “△t”is 10℃.　 Q＝2.778×10-7×1967.4×876×0.3×10　　　　　＝0.479×0.3×10≒1.4kW

Heat release value（ｋW）Constant pressure specific heat（Ｊ/kg℃）・・・1967.4Ｊ/kg℃Weight volume ratio（kg/m3）・・・876kg/m3

●Method 3: When motor output loss is considered to be the heat release value

When the output loss is 30% for the motor output 7.5 kW → The output loss is 30% or so in general （Cooling of main shaft head）Ｑ＝7.5×0.3＝2.3ｋＷ

Note）1. The larger the last number of a model name, the newer the series（For instance, AKS35K is newer than AKS33K）. 　In addition, a model having the last alphabetic characters “AK” is newer than a model ending with “K” only.（For instance, AKS35AK is newer than AKS35K）.

2. The cooling capacity is represented by the value at the standard point and at 60 Hz for all models.3. The dimensions of the equipment may be changed on a newer type and older type on some models. Please check the dimensions on the brochure and specification sheet （outline drawing） for selecting your equipment.

　When you are about to buy new equipment due to a failure of the equipment or for other reasons, please check the conditions of new equipment and select an appropriate type.

4. All the models have been changed to the inverter type since 2002.5. AKSZ（S）“7” series uses new refrigerant R407C, AKZ “8”, AKZ “9” series uses new refrigerant R410A, and all other models use R22.6. Existing units of 1HP class （AKS105AK, AKZ（S） 257 class） were integrated into AKZ328 of 1.2HP class.
