This new generation consists of four heat pump models based on the GEA Grasso M screw compressors H, L, M, N newly developed for 52 bar applications. The GEA RedAstrum transfers heat to a heating carrier at temperature levels between 55 to 80 °C which can be utilized in any industrial processes or fed into a district heating network.
Highlights & Technical Features:
- Optimum performance
- Compact footprint, comes in one piece
- Natural refrigerant Ammonia (R717)
- Maximum design pressure up to 52 bar(a)
- Single screw compressor / single stage operation
- Continuous capacity adjustment by VSD
- Heating capacity appr. 600 to 2,000 kW
- Hot water (glycol) supply up to 80°C
- Heat source (secondary refrigerant) inlet between -7 and +40 °C
- Heat source (secondary refrigerant) outlet between -10 and +37 °C
- Fully welded shell & plate heat exchanger
- Different plate materials available (acc. media requirements)
- Subcooler if required
- Combined heating and cooling possible
