Low GWP Chillers
The US, California, Canada and EU have implemented regulations to restrict refrigerants with high Global Warming Potential (GWP). Regulation effective dates vary, but in response to them SMC is introducing chillers with lower GWP refrigerants, either R454C (GWP 146) or CO2 (GWP 1) which are dramatically below new thresholds. These new chillers are offered in several categories and are designed to match performance, dimensions, port size and layout of legacy designs.
HRSF, Medium Capacity, General Purpose Chiller
HRSF medium capacity chillers offer cooling capacities of 1.3~5.9 kW. Coolant and refrigeration circuits are included in a compact package. The refrigeration circuit can be air or water cooled. Air cooled models use a single fan which operates at 68 dB(A) or less. Water cooled models can connect to facility water. Set temperatures are PID controlled, while the system is monitored for multiple alarms. Additional features include a heating function, serial communication, and a range of optional accessories.
- Cooling capacities, kW: 1.3, 1.9, 2.4, 3,2, or 5.9 (60Hz)
- Temperature range setting: 5~40°C
- Temperature stability: ±0.1°C
- Power supply requirement: single-phase 200~230 VAC (50/60Hz)
- Refrigerant: R454C (GWP 146) (Not available for air transport)
- Circulating fluid: Tap or de-ionized water, or 15% glycol aqueous solution
HRRF, Rack Mounted Thermo Chiller, Low GWP Refrigerant
The HRRF is a temperature control device mountable in a 19-inch rack. Rack mounting recovers desktop or floor space, permitting stacking of related devices and mobility, depending on the rack style. Recirculating fluid removes heat from the process source, which is then removed from the fluid by an air or water cooled refrigeration circuit. Air cooling employs an internal fan, while water cooling requires facility cooling water. Coolant temperature stability is ±0.1°C within a set temperature range of 5 to 35°C. This device is self-contained with coolant and refrigerant circuits, fan or water cooled heat exchanger, electronic controls, pump, tank and power supply.

HRSF, Large Capacity, Air Cooled, General Purpose Chiller
HRSF large capacity chillers offer cooling capacities of 15.7 and 20.5 kW. Coolant and refrigeration circuits are included in a compact package.
