Technology
What are high-efficiency chillers with natural refrigerant?
Air-to-water chillers (industrial chillers) that produce chilled water for air conditioning and industrial processes using propane (R290), a natural refrigerant. All of them include an isolated compressor module with ATEX extraction and an R290 leak detector, and can take an optional heat recovery unit.
The SILVER, with inverter screw compressors, covers 308 to 768 kW. The PURPLE, designed for industrial processes, and the PURPLEi, with inverter and EC fans, range from 30.5 to 291 kW and produce water down to −8 and −10 ºC. The PURPLE FC adds direct free cooling to chill water without running the compressors in winter and mid-season.

Selection criteria
When to choose high-efficiency chillers with natural refrigerant
- Industrial process cooling, including sub-zero temperatures (down to −10 ºC)
- Installations with year-round cooling demand, where free cooling cuts consumption
- Projects that require a natural refrigerant instead of fluorinated gases
- Installations that can use the heat recovered from the unit to produce hot water (optional heat recovery)
