R290 intarWatt – Full INVERTER

R290  chillers

Glycol, water or brine chillers with reduced R290 load and Full INVERTER compressors.


Glycol chillers for commercial and industrial refrigeration applications with reduced R-290 load and full INVERTER compressors. Our R290 intarWatt chillers are characterised by:

  • Incorporating Full INVERTER compressors.
  • Natural Refrigerant R-290.
  • High energy efficiency.
  • Easy installation.
