The connection to the earth's energy source will be guaranteed through the FRANK Geothermal System. Geothermal probes are installed vertically into the ground as shown above.
A cold heat transfer medium circulates through the probes, absorbs the geothermal energy from the ground and dispenses it to a heat pump. The heat pump increases the provided temperature via a thermodynamic process and delivers the heat to a buffer tank for heating and hot water.

Heat pumps transform geothermal energy by using 1 kWh of electricity into 5 kWh of usable heat, e.g. you can cover 100% of your heat requirements by 20% energy input.

The geothermal probes from FRANK are delivered completely assembled. The foot of the probe is welded with special developed welding equipment and inspected personally.

As a third party, the Governmental Institute for Material Testing [Staatliche Materialprüfanstalt Darmstadt] ensures, the production of the probes is according to the corres- ponding SKZ-guideline HR 3.26.

Our probes meet all the current norms.

PKS-Thermpipe

By using the PKS-Thermpipe®-System, industrial and private buildings can be heated cost-effectively with energy from sewage and geothermal power of the pipeline zone.

A novel plastic spiral pipe allows using the energy potential of soil and sewage simultaneously, making this system independent of irregular waste water discharges.

The temperature of sewage averages around 20 °C throughout the year. Even moderate lengths of pipelines can be sufficient to supply modern buildings with enough energy.

Available in lengths of 3 and 6m,
DN 300 to DN 2000
