Robur (booth 4135) has announced its new line of Gas Absorption Heat Pumps. This new generation of heaters and chiller-heaters, developed and perfected by Robur, provides cooling and/or heating from a single unit operating on natural or propane gas. Peak heating efficiency higher than 135% (when compared to heat energy consumed on HHV; 150% on LHV) is possible. Minimal electricity is required (versus the traditional electrical system) by using a single gas burner that produces both hot and chilled water simultaneously. An extremely low fuel co,nsumption in the heating mode is possible due to the recovery of energy from the air, water or ground. Robur.
