CALPEX is a bonded pre-insulated, self-compensating and flexible piping system suitable to transport low temperature hot water from a heat source underground losing minimal heat.
The advanced insulation technology with polyurethane foam and the sustainability of the system make CALPEX a long-lasting solution. CALPEX can be laid out in a quick and uncomplicated way and remains operational for decades: an investment that more than pays for itself in the long term.
CALPEX can be used in District Heating, Central Heating & Sanitary applications. It will carry water from Gas/Oil Boilers, Wood Pellets Boilers, Heatpumps, Hot Water Cylinders and many other applications
Features:
Water ingress is hardly worth thinking about with CALPEX because a bond is created between the inner tube and the insulating foam due to a 97% closed cell structure. This closed cell structure therefore will not allow water to ingress through the insulation in the event of damage to the outer protective cover unlike some similar products on the market.
The quality of a low temperature system lies in the heat insulation. The insulation of the CALPEX pipe consists of fine-pored polyurethane foam that is blown using pentane. With a low volume and thin insulation, this achieves an excellent Lambda value of 0.0216 W/mK making CALPEX the best insulated pipe available on the market. The low heat loss saves heating costs and reduces energy consumption over the long term.
