Screw Chiller A-SK Series


Provide chilled fluid for industrial applications from a central location
with the Conair Air Cooled A-SK series central chillers.

The simple design of screw compressors provide both full load and
part load efficiencies unmatched in the industry, and results in lower
energy costs when compared to reciprocating compressors.

  • Sight glass indicates the status of dry or moist system.
  • Option of eco friendly refrigerant also available.
  • Small unit size, factory wired, easy lifting procedure, easy start up logic.

Features (click here to hide)

Rugged compressor design with only four moving parts, eliminating the need for pistons, connecting rods, wrist pins, and valves.  Less moving parts means less internal
friction and greater efficiency.

Semi hermitic screw compressors with two shaft designs with suction and discharge solder connection, integrated check valve, integrated pressure  relief valves, flanged
on oil separator, oil filter, and oil sight glass.

All chilled water contact surfaces are non ferrous for protection against corrosion.  All wetted surfaces are stainless steel, copper, or other non ferrous metal.

Small unit size, factory wired, easy lifting procedure, easy start up logic.

Stainless steel shell & tube evaporator with seamless internally finned copper tubes for higher surface area.

Strainer protects the evaporator from solid contaminations in the process water.

Flow switch is used to detect flow loss as a safety precaution of evaporator when return  water flow is low.

Electronic expansion valve is used to regulate the flow of refirgerant in the evaporator as per the load of system to maintain the suction superheat.

Finned and tube heat exchanger with internally grooved imported copper tubes having higher surface area suitable for high ambient condition.

Removeable cartridge type filter dryer to ensure moisture free system and quick change features.

Sight glass indicates the status of dry or moist system.

Pressure switch protects the compressor agaisnt low and high pressure.

Monitoring of suction and discharge refrigerant pressures.

Antifreeze protection to safe guard the evaporator & compressor against low temperature.

Option of eco friendly refrigerant (R134a) also available.

Helical screw design results in part load performance.

Latest heat transfer technology results in increased condenser and evaporator tube efficiency.

 Reduced rotor clearance results in reduced leakage between the high and low pressure cavities during compression.

Resistant to liquid slugging, this compressor design can handle amounts of liquid refrigerant that would severly damage a reciprocating compressor.
