GA ACF 60 Hz
Gas-powered absorption chiller
Low-energy consumption cooling.
Benefits
- Reduce cooling costs, including electricity consumption. HFC-free gas absorption chillers ensure continuous operation and low maintenance thanks to compressor-free technology.
- Cooling with extremely low electricity consumption.
- Available in Natural Gas or Propane versions.
- Single-phase power supply. Only 0.75 kW electrical power consumption for a 5 TON modular chiller.
- Proven savings: up to 86% less electricity consumption. Peak electrical demand is reduced to less than 0.75 kW, eliminating the need for large and costly back-up generators.
- Uses a natural refrigerant: ODP = 0 | GWP = 0 | HFC-free | PFAS-free.
