CALPEX-R (A) is Calefactio’s transluscent cross-linked pex pipe. It is designed for use in radiant heating and snow melting systems. They are built with an anti-oxygen barrier that limits oxygen diffusion through tubing walls to less than 0,10m3/day at 104°F, thus protecting system components. This tubing meets DIN4276 norm criteria and conforms to SDR-9 dimensions. CALPEX-R (A) is designed to resist a maximal pressure of 160PSI @ 73,4°F (23°C), 100 PSI @ 180°F(82°C) and 79 PSI @200°F (93°C). CALPEX-R (A) can be used in potable systems as it is certified NSF14. The CALPEX-R (A) tubing is compatible with propylene and ethylene glycol.
