High-Temperature CO2 Heat Pump Can Increase COP of Spray-Drying Systems by 60–75%
GEA has been studying integrating high-temperature CO2 heat pumps with conventional heaters to preheat the process air of spray-drying systems since 2019.

The Annex 58 high-temperature heat pump project has reviewed systems supplying temperatures over 100°C and found refrigerants like CO2, water, hydrocarbons, helium and ammonia being used.
