Provision of geothermal energy

Energy-efficient heating and cooling with GEOZENT

Thermal energy from the ground is available free of charge almost everywhere for resource-saving heating but also as cooling technology for cooling down buildings. For more than 15 years, Zent-Frenger Energy Solutions has been working on technologies for thermal energy generation from geothermal energy near the surface. A key building block for using this is the geothermal heat pump, which we produce project-specifically as a complete energy centre in the power ranges 50-1,500 kW in our plant in Heppenheim, Germany.

The large-scale heat pump system offers a broad range of functions for all commercial applications with heating and cooling, dual operation, natural operation and hot water preparation (suitable for large commercial buildings). The additional use of waste heat increases the efficiency of the plant.
