Heat pumps with environmentally friendly refrigerant R744 (CO2)

High temperature heat pumps from ENGIE Refrigeration

Our high temperature heat pumps work exclusively with the future safe use and environmentally friendly refrigerant CO2 (R744) and provide hot water temperatures of up to 110°C under the use of various heat sources, e.g. outside air, process heat.
Low heating return temperatures in the so-called transcritical CO2 recycle process result in lower energy loss than conventional heat pumps with a subcritical cycle.
Heating processes such as drinking water preparation and process water heating allow low return temperatures and can therefore be implemented with higher-performance CO2 heat pumps.

Technical Info and their advantages
  • solid construction, a robust industrial design with high quality components
  • effective power control is realized with a frequency converter or in stages through compressor shutdown
  • programmable logic control (SPS) with a comfortable touch panel, integrated in the control cabinet takes care of the control and regulation
  • only power electrical connection, cold or hot water connections and the control centralized system are necessary on site

 

CO2 as refrigerant
  • Climate neutral and environmentally friendly
  • without environmentally hazardous decomposing products
  • no additional contribution to the greenhouse effect (GWP=1)
  • does not contribute to ozone layer destruction(ODP=0)
  • no leak control mandatory
  • no disposal and recycling requirements
  • no availability restrictions
  • no taxes = long-term cost-effectiveness
  • low safety requirements - Safety class A1
  • non-toxic, non-flammable, thermally stable material-compatible
  • natural production
