JANSEN geotwin

The new generation of ground source heat loops

As standard, JANSEN geotwin ground source heat loops are manufactured from notch-resistant, high-quality PE 100 RC material of the latest generation with innovative production technologies.

Optionally they can also be manufactured from high-temperature resistant PERT material. The heat loop base welded on in the factory is delivered with an individual factory certificate in accordance with EN 10204. Each heat loop can be identified by its serial number; this number is used for complete traceability from the raw material used to the site. The unique, patented double-pipe winding gives the JANSEN geotwin its name and offers various advantages such as:

Quick, straightforward reel mounting
Even unwinding
External pipe ends
Very little space required
Detachable heat loop base
Reinforced sides
Sleeve-mandrel welding
Hydraulically optimised channel
Pipes made of PE 100 RC of the latest generation
