An evaporator, Compressor, Condenser and Expansion unit are the main components of a chiller unit. Every chiller system contains a refrigerant.

• Air-cooled chillers: Air-cooled chillers are among the most commonly used refrigeration systems for commercial and industrial facilities.
  • Lower installed cost and maintenance due to its simple construction.
  • No handling problem with air
  • Used for low capacity
  • No problem in disposing of used air
  • Tower and mechanical room not required.
  • Adapt to most climates.

• Water-cooled chillers:
  • Used for large capacity, especially industrial plants
  • Can operate on lower condensing temperature
  • Higher efficiency
  • Longer life
  Both Air chillers and Water chillers are very alike components. The predominant difference between Air &Water chillers is the way of ejecting unwanted heat.

• Chiller Compressions: It uses a mechanical compressor to force a refrigerant around the cooling system. Sometimes compression is paired with refrigerated air driers to get rid of potentially harmful Moisture in the chilled air

• Screw compressor chillers:
  • Can use in both water- and air-cooled chillers
  • Best choice for small, medium cooling loads
  • Manufactured using high-grade material procured
  • The male and female rotors are rotating in the opposite directions they draw air between them.

• Reciprocating compressor chillers:
  • Good for small application
  • Low/no consumption power while unloading
  • Simple construction makes operation easy
  • Operates over a wide range of pressure
  • Easy maintenance

• Centrifugal compressor chillers:
  • Good for high-pressure applications
  • Low maintenance and running cost
  • Does not require a special foundation
  • Can be 1500 HP or larger

• Scroll compressor chillers:
  • Best for large-scale air-conditioning applications
  • Less noise and vibration
  • Fewer moving parts and less torque
  • More efficient than standard compressors
