GA ACF HR 60 Hz
Gas absorption chiller-heater with heat recovery
Cooling and simultaneous production of free hot water thanks to heat recovery.
Benefits
- Cooling that saves you money, even in electricity use. Gas absorption chillers, HFC-free, which guarantee operational continuity and reduced maintenance as they do not use compressors.
- Cooling with negligible electricity use.
- Natural Gas or Propane.
- Single phase. Only 0.75 kW electric consumption for a 5 TON modular chiller.
- Real savings: electricity -86%. Drastic reduction of electric demand charge (less than 0.75 kW electric consumption) and no need for big and expensive back-up generators.
- Natural refrigerant: ODP = 0 | GWP = 0 | HFC and PFAS free.
Applications
- Ideal for hotels, wellness and sports centres.
- Can be used in post-heating circuits connected to air handling units.
