Demonstration of a Hybrid Air Heater Combining a Gas Burner-Based Hot-Air Generator and a Heat Pump

「To improve the efficiency of hot-air supply for applications such as paint drying, the company began demonstration testing in October 2016 for the development of a "Hybrid Air Heater" combining a gas-fired hot-air generator manufactured by ㈱桂精機製作所 and a heat pump manufactured by ㈱前川製作所. A heat pump offers higher energy efficiency than a gas-fired hot-air generator when hot air and chilled water are used simultaneously and at temperatures of up to approximately 80°C. A gas-fired hot-air generator is a device that efficiently produces hot air at temperatures of approximately 200°C by burning gas, which a heat pump cannot produce.」
