The GeoCollect® Absorber modules are designed to absorb valuable energy from the earth surrounding them. Owing to their special surface properties and their filling with a water/glycol mixture, this is done safely and efficiently and an installation depth of 1 to 2 metres is absolutely sufficient. To ensure that the surrounding earth can regenerate adequately and regularly, appropriate dimensioning must be observed. The water/glycol mixture serves as heat transmitter and transports the energy from the earth to the thermal pump.
