POWERFUL FEATURES:

Exceptional Energy Efficiency by Design

• Basic equipments are designed to operate compressors on a comparatively better suction pressure and

an optimum discharge pressure, to maximize efficiency benefit.

• Compressor with step-less capacity control mechanism, operates in response to the chilled water outlet

temperature, and precisely matches the part-load requirements without hunting.

• Electronic expansion with controller and sensors, respond quickly to the variable operating conditions

and enhances efficiency.

• Compressor staging has been programmed to save energy, by running adequate numbers of

compressors at maximum efficiencies, even at different loads.

• Economizer greatly improves efficiency of the unit and full-load cooling

capacity. Additional sub cooling is created by expanding one part of liquid

refrigerant from condenser, to sub cool remaining part of total refrigerant,

in a compact plate-type heat exchanger (PHE).

• The Economizer’s working process is depicted in the diagram.

• Screw compressor is provided with an additional suction port called ECO port,

which makes it possible to suck the refrigerant vapour from PHE, to accomplish

economizer heat transfer.

Screw Compressors Mean Efficiency and Reliability

Screw Compressors are sourced from industry’s best

manufacturers, and are tested in accordance with ARI / Eurovent

standards. The Compressors are known for efficiency, ruggedness,

reliability and consistent part-load operations.

Salient features of these compressors are:• Compressor is suitable to operate at 415V, most suited for Indian Operating Electrical Environment.

• High-efficiency due to scientific profile design of screws, high-speed operation and precision controls.

• Step-less capacity control from 100% to 25% for each compressor.

• These are semi-hermetic type compressors and hence, easily serviceable.

• Robust and proven construction with double-walled, single-housing and new slider technology.

• Each compressor is provided with a self-motor protection module, PTC motor winding protection, oil

temperature protection, oil level switch and oil heaters - all these guaranty reliability and long life.

• Multistage and ultrafine, inbuilt oil-sepa rator results in less oil carryover rate.

• Double casing structure with high strength inner ribs ensures Lower sound level.

Oil Separation & Recovery system:• Chiller is provided with additional Secondary oil separator to minimize the oil carry over.

• Unique Oil separator design ensures high filtration efficiency at varying load conditions & low pressure

drop.

• Oil Supplied by pressure differential hence oil pump is not required.

Electronic Expansion Valve (EXV) – Precise and Efficient Control

EXVs are used to maintain a precise �ow of refrigerant to the evaporator, under both full-load

and part-load operation of the compressor. It can precisely control superheat at the outlet of the

evaporator with faster response, irrespective of the wide variation in capacity. EXVs are an

improvement over conventional thermostatic expansion valves and enable reduction of energy

loss and hence, improve overall efficiency of chillers.

The EXV operation is controlled by an electronic controller module, which is user-friendly and

provides multiple application options. It is provided with battery back-up so that in case of a

power failure, EXV can close positively and stop any liquid �ood-back to compressor.

Water-cooled Condenser

Advanced design tools like HTRI are used in water-cooled screw chillers for sizing of heat

exchangers. The unit is made compact with advanced high heat �ux tubes and designed for

optimum performance.

• Doubly Enhanced & highly efficient finned copper tubes

• Impingement Protection at Hot gas Inlet ,eliminates vibration, noise

• Two or Three water passes available

• Removable water heads

• Victaulic Groove Water Connections

• Relief valves

• Manufacturing of shell from high-grade steel

• Condenser design as per ASME section VIII Div 1


5

Flooded Chiller – Maximising efficiency

The evaporators are manufactured using imported

and highly efficient, compact ridged inner-finned

copper tubes, which are mechanically expanded for

better fitment.

Chillers are fabricated and pressure-tested, as per

relevant standards for pressure vessels. Each chiller

model design is validated by special design software

and optimized for efficiency, refrigerant / water

velocities and pressure drops.

Micro-computer Control Panel

Advanced micro-computer control is a standard feature on all

Voltas Screw Chillers. This maintains all analog and digital inputs to

achieve precise control of the operational and protective

functions of the unit. Direct Digital Control (DDC) allows

fingertip user interaction. The easy-to-use, push-button key board

and menu-driven software provides access to operating

conditions, control set points and alarm history, displayed on a

alpha-numeric LCD.

User-friendly Operation Modes

• Programmed Auto Mode: Auto-start and stop are programmable for an entire year. This

minimizes operator interface and facilitates auto-restart on power restoration after load

shedding or grid supply failure.

• Auto Mode: Start-and-Stop of the unit is controlled manually by a single button. Subsequent

operation of the unit is fully automatic through microcomputer control.

• Test-service Mode: Facilitates testing of the unit under supervision.

• Remote mode (for Hardware BMS): Facilitates switching the unit on/off from a remote location

through Hardware BMS. Panels are provided with three additional digital outputs and one

digital input (start key) hardware BMS, as a standard scope of supply.

• BMS Compatibility with Modus/BACnet


Display Information

Easily accessible measurements include the following parameters:

• Entering / Leaving chilled water temperature

• Entering / Leaving cooling water temperature

• Number of compressor starts

• Suction pressure

• Remote / Local operation option

• Discharge pressure.

• Oil level fault indication.

• System voltage

• Compressor ON / OFF status

• Compressor current for each compressor.

• Compressor load percentage for each compressor

• Compressor elapsed run time for each compressor.

• Discharge gas temperature.

System Protections

The following system protection controls will automatically act for protecting the

chiller under abnormal conditions, and ensure system reliability and safety.

• Low suction pressure

• Compressor over current, for each compressor.

• High discharge pressure.

• High winding temperature.

• High discharge gas temperature.

• Freeze protection

• Sensor error

• Chilled water �ow

• Single phase and phase reversal.

• Low oil level

• Over / under current and current imbalance

• Anti recycle

• Preventive maintenance due trip

• Over / under voltage and voltage imbalance.

Diagnostic Displays

The diagnose mode provides for easy trouble – shooting.

• Unit trips 50 hours prior to completion of 8000 hours, as a precautionary measure, for

preventive maintenance.

• Alarm history of last 10 trips with date, time and causes of failures.

• Protection trips for various vital parameters.

Adaptive Control

• Discharge / suction pressure limiting is done by unloading. This offers the advantages of chiller

running unloaded, instead of tripping.

• In case the compressor current increases above set valve, the microcomputer senses the

increase and signals the computer to unload, thus maintaining current within set value.

Voltas countrywide after – sales service

• A nationwide service network backs every unit.

• After the initial warranty period, Voltas offers annual maintenance service schemes.

Smooth sine wave improves motor efficiency

Voltas's magnetic bearing inverter centrifugal chiller adopts high-speed

motor to directly drive the 2-stage impeller structure. We eliminate speed-up

gears and 2 radial bearings to reduce mechanical loss and improve energy

efficiency. Compressor is compact and reliable. Volume and weight of the

compressor is only 40% of the same capacity conventional compressor.

Speed-up wheelwork is eliminated. Without the high-frequency noise of

gears, compressor's operating sound is much lower. That is 8dBA lower

than that of a conventional unit.

Two-stage compression and the patent diffuser technology have greatly expanded the unit's operating range. It can

operate stably when entering cooling water temperature is 12-35°C. It can realize stepless regulation at 10-100%

load.

Conventional inverter centrifugal chiller adopts variable rotation speed + guide vane to adjust cooling capacity and

will begin to turn down the guide vane at 50-60% load, which is not energy-efficient. In comparison, Voltas

permanent magnet synchronous inverter centrifugal chiller can adjust its rotation speed at 25-100% load, which can

reduce the throttling loss of guide vane and improve energy efficiency.

Pr oduct Feat ur es

Two-stage compression with flash gas ecomonizer is more efficient when compared to single-stage

compression. The refrigerating efficiency is improved by 5-6%. It has lower running speed, higher reliability, and

longer service life. In addition, two-stage compression enables large flow angle for impeller outlet, large surge

margin and wider operating range.

Voltas VLCCE Series Magnetic Bearing Inverter Centrifugal chiller was developed by Voltas. It

is a permanent magnet synchronous inverter centrifugal chiller that adopts magnetic

bearing technology. Its cooling capacity is 100 RT – 1100RT. The application of permanent

magnet synchronous motor (PMSM), 2 stage compression, motor direct-drive impeller, and

4-quadrant inverter has greatly improved the chiller’s energy saving performance.

Meanwhile, magnet bearing is adopted for oil-free operations. The reliable microcomputer control system, group control

technology and building communication interfaces have also contributed to the fine operation quality. It is applicable for

Hotels, office buildings, business clubs, etc.

Voltas Magnetic Bearing Inverter Centrifugal Chiller

The essential part of the chiller is the magnetic bearing centrifugal compressor that consist of impeller, motor, magnetic

bearing, displacement sensor, bearing controller and motor driver. It utilizes magnetic field to keep the rotor suspended so

that there won’t be mechanical friction during rotation. By using magnetic bearing, lubricating system is no longer necessary

in a refrigerating compressor. Thus, central air conditioners are more energy-efficient.

Voltas has a wide range of Products and equipment for the various applications meeting high standards of quality, efficiency,

reliability and industrial norms. With in-house Engineering and Manufacturing of major components like Compressors,

condensers, chillers, pressure vessels and automation components, we offer complete customize solution to fulfill all

expectations of customer for reliable operations of the system. With ISO 9001:2015 standard certified factories, Voltas

possesses total capability on the manufacturing of the chillers.
