R290 chillers

Indirect commercial and industrial refrigeration systems:

Sigilus R-290 | Chillers
Is the range of chiller in silent air-condensed construction for commercial refrigeration applications, using a low propane charge as the primary refrigerant contained in the chiller, and water, glycol or brine as the secondary refrigerant for cold transport.

intarCUBE R-290 | Chillers
Water, glycol or brine chiller for commercial and industrial refrigeration applications with reduced
R-290 load, in footprint construction with built-in hydraulic unit.

intarWatt R-290 | Chillers
Water, glycol or brine chiller for outdoor industrial refrigeration applications.

NEW Full INVERTER R-290 | Chillers
New glycol chillers for commercial and industrial refrigeration applications with reduced R-290 load and full INVERTER compressors.
