Kilfrost GEO Plus is a next-generation, non-toxic low viscosity heat transfer fluid developed to optimise the performance, reliability, and safety of closed-loop ground and water source heat pump systems. Designed for demanding environments, it combines exceptional thermal efficiency with robust system protection, helping operators to achieve lower running costs and reducing environmental impact.
Certified for safety
In addition to offering all the proven benefits of Kilfrost GEO, GEO Plus is certified to the US NSF standard for incidental food and beverage contact (NSF Non-food Compounds HT1 Registration No. 158939). This certification gives added assurance for applications where safety is critical.
Kilfrost GEO Plus’s advanced formulation uses bio-derived base fluids listed as GRAS (Generally Recognised as Safe) by the FDA, along with rheology modifiers and ASTM D1384-05 proven corrosion inhibitors. The result is a low-viscosity fluid that flows more easily through the system, reducing energy requirements associated with pumping, and delivering greater efficiency than traditional mono propylene glycol (MPG) based fluids.
Kilfrost GEO Plus is engineered to maintain long-term stability, resist degradation, and protect system components, ensuring optimal performance throughout its service life.
