Calpex system, the most efficient on the market.
Highest insulation capacity compared to competitors on the market
CALPEX is a patented flexible, continuous and self-compensating low temperature piping system with the world's best lambda value of 0.0199 W / m*K. This exceptionally low value is tested and confirmed annually by an accredited testing institute. 
This record figure has made it possible to exceed the previously thought lower physical thermo-conductivity values for polyurethane by a significant amount. CALPEX is therefore becoming the trigger for another significant increase in the energy efficiency of pre-insulated piping systems for the heating and cooling market.
