Made from renewable raw materials

Due its physical design and storage properties, the GEOKOAX ground heat exchanger requires much less freeze protection than conventional U-bends. This increases conductivity. The frost protection of the GEOKOAX biological heat carrier fluid CORACON GEKO E is based 100 % on renewable raw materials, while conventional brine fluids are based on fossil monoethylene glycol or monopropylene glycol. CORACON GEKO E contains biodegradable materials, which have been even approved for food use, to prevent system corrosion.

Conventional liquids

We offer CORACON GEKO N, a liquid for application in less sensitive areas. This brine can be used with a proportion of as little as 17 Vol-%, as it contains sufficient anti-corrosion agents.
