Ecology:

• Choosing environmentally friendly refrigerants: R417A, R1234ze or R290These refrigerants are environmentally safe and meet modern standards.
• High leaving water temperature:
  • Ground-water heat pump DUAL 75 kW with refrigerant R407, R417A: up to +60°C.
  • Ground-water heat pump DUAL 75 kW with refrigerant R1234ze: up to +65°C.
  • Ground-water heat pump DUAL 75 kW with refrigerant R290 (on special order): up to +70°C for heating and up to +75°C for DHW.
• No additional electric heating elements are required to increase the water temperature.
• The use of geothermal energy allows for the reduction of the carbon footprint and the extraction of up to 75% from energy from renewable resources.

Flexible installation guide:

• The compact heat pump housings facilitate installation even in confined spaces.

Benefits of the DUAL 75 kW geothermal heat pump

1. High reliability:
   • The dual-compressor construction ensures stable and durable operation even under intensive use.
