Waterkotte Launches Serial Production of R290 Geothermal Heat Pump Industrial Line 8060.7

Waterkotte has commenced serial production of the Industrial Line 8060.7 geothermal heat pump, using R290 refrigerant with a rated capacity of 60 kW. By the end of 2026, the company plans to expand the range with the 8120.7 model, offering a capacity of up to 120 kW per unit, extending the series range to 120 kW.

Applications and Specifications

The heat pump is designed for multi-storey residential buildings, commercial, and industrial facilities. The heat source is groundwater or a ground mass (soil). The unit provides heating, cooling, and domestic hot water preparation in both new and retrofitted buildings with elevated capacity requirements. In cluster mode, multiple units operate together to achieve a higher total output.

Safety and Controls

The R290 refrigerant has a global warming potential (GWP) of 0.02. The built-in safe ventilation system eliminates the need for a separate machine room in accordance with DIN 378: a radial fan creates a continuous, sensor-controlled underpressure exhaust that, in the event of a leak, directs escaping refrigerant outdoors. The control concept allows independent regulation of the refrigeration and hydraulic circuits, which, according to the company, ensures a more continuous operating mode. Controls are managed through a full-graphic system with software and a built-in web interface for remote monitoring. A heating circulation pump is integrated into the design; dimensions are compact, and the floor footprint is minimal.

Production

Assembly takes place at the company's plant in Bochum. In addition to equipment for the German market, this facility will produce heat pumps with capacities above 30 kW for other companies within the Nibe group.
