Screw Chiller

Screw Chiller

Hems Infratech Pvt. Ltd. offer a comprehensive range of Screw Chiller includes Air Cooled Screw Chiller and Water Cooled Screw Chiller. These Chillers are energy efficient and robust in construction and are developed with latest technology. They include optimized screw compressor, highly efficient DX cooler, condenser, highly efficient copper tubes are also incorporated in the chiller. The units have a very low input kW/TR and are tested in our state-of-the-art test lab to validate the performance.

Screw Chiller:

We are engaged in offering our clients a wide gamut of Screw Chiller that is best known for its quality. Our range meets international quality standards and performs efficiently under heavy loads. Our chillers are comprised with Automatic Capacity Control System and Screw Compressors with Single and Twin Screw arrangements and with required fittings. These chillers are available with variety of Low / Medium temperature range. Moreover, these are available with various specifications and capacities as per the needs and demands of the clients.

Standard Features:

  • Wide operating map for applications ranging from comfort cooling to ice making
  • Two refrigerant circuits improve part load efficiency
  • Single main rotor compressor means inherently quieter operation than dual rotor compressors
  • Compact size fits through a 3-foot door for lower installed costs
  • Solid state starters with less compressor stress and vibration
  • Fixed speed design compressor results in lower drive and first installation costs
  • Tight clearance with ground screw rotors and high precision bearings
  • Minimize installation cost with one of the smallest footprints in the market
  • Minimize operational costs with low repair and maintenance costs
  • Standard components for relative ease of service by less-skilled technicians


We offer Air cooled Screw Chillers that are manufactured with high quality raw material to meet international quality standards. The chillers are designed for ambient temperatures of up to +50 degree centigrade. The fluid temperatures can go down to -30 degree centigrade. The range of capacities starts from 175 kW to 1575 kW. Our range of chillers is highly acknowledged by our clients because of its salient features that include high quality, best performance, high efficiency, reliability, etc.


  • Low voltage control circuits with leakage rate at less than 0.1%
  • Hermetically sealed compressor motor
  • Automated controls may be tested before start-up
  • Password protected extensive service menu with built-in diagnostic capabilities
  • Alarm and alert files maintain the last 25 time and date stamped messages in memory
  • Configuration data backup with non-volatile memory
  • Thermistor type temperature sensor with quick connects in each water nozzle
  • Modular construction with Refrigerant filter isolation valves
  • Can be dismantled and reassembled with Single point electrical connection

Hems make water cooled chiller features as highly efficient and reliable heat exchanger Flooded type (optional)/ dry type evaporator and shell & tube condenser, with unique heat exchanger structure and optimum copper pipe combination, enhance the heat emission and exchange efficiency greatly.

Advanced twin screws compressor with optimum structure can realize automatic step less or 4 steps capacity control to achieve high efficiency. Running noise is low thanks to low friction area inside the compressor. The compressor has a long lifetime profiting from high performance of interior oil segregator.
