Get more cooling and DHW out of your dollar

Utilizing the Robur Gas Fired Chiller with Free Hot Water Recovery will provide you with the flexibility you need in a chilled water system while lowering your annual costs for cooling and domestic hot water production and/or process hot water.

1. Heat recovery during cooling operation, providing a valuable free source of hot water production up to 176°F while reducing the need of energy consumption from water heaters or boilers.
2. Utilization of a gas burner and “thermal compressor” to provide flexible chilled and hot water production which drastically lowers electric demand charge costs and peak loads.
   Only 0.75 kW (Single Phase) per 5 tons of cooling.
3. Simultaneous production of chilled and hot water for a variety of application types whether it be commercial, industrial or residential needs.
4. Environmentally friendly system that incorporates a truly green refrigerant with No Ozone Depletion Potential and Zero Global Warming Potential, low Nox, and even reduces CO released into the atmosphere.
5. No mechanical compressors which means that the life expectancy of the Robur system is twice that of typical electric equipment.

Utilizing the Robur ACF60-HR for gas fired cooling and free hot water production can save you thousands.
