DUNHAM-BUSH

Air Cooled Scroll Chillers

(ACDS Series)

Cooling capacity from 10~180 TR (35~633 kW) for 50 Hz & 60 Hz units

  • Using environmentally sound HFC-410A refrigerant
  • Reliable Tandem or Trio scroll compressors with high EER
  • Motor protection via embedded PTC sensors, protects motor overheating caused by overload, low refrigerant flow and incorrect motor rotation
  • Compact and high efficiency brazed plate heat exchanger evaporator, allowing lower pressure drop on water side

Helios Air Cooled Screw Chiller (ACHX-A)

Cooling capacity from 80~282 TR (281~992 kW)

  • Multiple compressors models with independent refrigerant system per compressor provide redundancy and superior part load efficiency
  • Operates with environment friendly refrigerant R134a with zero ODP
  • Economizer consists of plate type heat exchanger, expansion valve and solenoid valve. Increased cooling capacity by increasing sub-cooling and improve efficiency

Water Cooled Scrolled Chillers (WCS Series)

Cooling capacity from 12 - 62 TR (42 - 218 kW)

  • Scroll hermetic type compressor with EER, with thermostat fitted to prevent thermal overload
  • Scroll compressor delivers higher efficiency, fewer required components increases reliability and quieter operation
  • Evaporator with high efficiency inner-fin tubes design for compactness and weight reduction

Water Cooled Screw Chillers (WCFX-E Series)

Cooling Capacity from 60 - 1000 TR (211 - 3517 kW)

  • Economizer increased cooling capacity by means of the sub-cooling circuit, or 2-stage refrigerant expansion
  • Vertical Screw Compressors design guarantees rotor lubrication which rotor bearings are submerged in oil whenever compressor is in operation
  • Unique Patented Twin Screw compressor technology offers efficiency improvement, high reliability and lower sound level

Variable Speed Water Cooled Screw Chiller (WCFX-V Series)

Cooling Capacity from  133~747 TR (467 - 2627 kW)

  • Unique Patented Twin Screw compressor technology offers efficiency improvement, high reliability and lower sound level
  • Economizer increased cooling capacity by means of the sub-cooling circuit, refrigerant is sub-cooled at economizer before entering evaporator
  • Flooded type evaporator with shell-and-tube type heat exchanger

Centrifugal Chiller (DCLC Series, DCLCD, DCLCT Series)

Cooling Capacity from 300~4000 TR (1055 ~14068 kW)

  • Semi-hermetic compressor and motor are direct gear driven for reliable operation
  • Dual lock design on evaporator vessel's tube sheets ensure better sealing and minimizes the possibility of leaks between water and refrigerant system
  • Copper tubes with enhanced profile and grooves for best heat transfer efficiency
