R290 Sigilus

R290 chiller

Chiller in silent air-condensed construction with glycol, water or brine and a low charge of R290.

Description

R290 Sigilus 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 or glycol as the secondary refrigerant for cold transport. These chiller plants are characterised by:

  • A tropicalised design for ambient temperatures of 45°C.
  • 100% factory tested equipment.
  • Acoustically insulated scroll compressor.
  • Built-in hydraulic unit (optional).
