HEAT INSULATION

Heat loss calculation: For the calculation of the heat losses for PEX single and double pipes, for the conductivity of the pu-foam is a mean value of 0.022 W/mK assumed. 

SHROUD SYSTEM

If your installation need couplers or tees. We offer a new CLICK shroud system guarantees highest quality on construction site, without time-consuming bonding, shrinking or screwing, with secure connection technology and best thermal insulating properties.
