Made from renewable raw materials

Made from renewable raw materials

Due its physical design and storage properties, the geoKOAX heat exchange probe requires much less protection from frost than conventional probes. 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. Biodegradable materials, which have been approved for food use, are used to prevent 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 10 Vol-%, as it contains sufficient anti-corrosion agents.
