Air Cooled Screw Chiller R134a

Blue Star, India's Largest central airconditioning company has been providing expert cooling solutions for over six decades. it has been manufacturing a wide range of chillers for over two decades. Drawing from this expertise, Blue Star presents a wide range of air cooled screw chillers with environment-friendly R134a refrigerant.

These chillers are manufactured at Blue Star's own ISO 9001 certified factory with the chiller test bench certified by Airconditioning, Heating and Refrigeration Institute(AHRI). Blue Star screw chillers are equipped with effective capacity control, They provide excellent efficiency making them ideal for varying load applications such as office spaces, hotels, hospitals, malls and multiplexes.

Air Cooled Screw Chillers from Blue Star are available in two series:

The salient features of these compressors are:


Refrigerant liquid-to-liquid plate type heat exchanger is provided for the Economiser system. The liquid refrigerant is sub-cooled to enhance the capacity, thereby reducing specific power consumption (IKW/TR) and enhancing the Coefficient of Performance(COP).


The shell and tube evaporator has been built using imported, internally enhanced and highly efficient finned copper tubes and has been optimised for refrigerant and water velocities. The expansion of the tube is done with torque controlled process.

Air Cooled Condenser

Liquid Injection

The refrigerant suction gas cools the winding of the semi-hermetic screw compressor motor.During the part load operation where the suction gas circulation is less, as a precaution, liquid refrigerant is injected into the suction side of the compressor to cool the motor winding. This is done to keep the motor winding temperature within limits. it is provided as a standard feature to enhance the life of the compressor.


The chiller is incorporated with 5-lobe, bird-wing design fans. This profile optimises the noise level as well as power consumption against the required airflow and static pressure.

Spring Isolators

Specially designed spring isolators are supplied along with the units to minimise the transmission of vibration.
