FRANK GET-X geothermal probes

Geothermal probes made of cross-linked polyethylene PE-X offer ideal protection against point loads, slow tear growth and external damage.
FRANK GET-X probes are manufactured from proven FRANK SurePEX pipes made of peroxidically cross-linked polyethylene and a factory-welded probe foot. During the production of SurePEX pipes using the Engel process, more than 2,000 bar of pressure cross-links the molecule chains to one another during extrusion. This homogeneous type of cross-linking makes the pipes resistant to stress cracks.
The GET-X probe is perfectly suited to use in heat stores and in connection with solar heat.
