PRE INSULATED pipes and fittings are insulated with high energy efficient (HE) foam and protected with a robust jacket. It is a corrosion and condensation free solution for the transport of chilled water inside residential and commercial buildings as well as data centres and for process cooling. The smooth inner surface of the thermoplastic PE pipe provides a minimum pressure loss while the low thermal conductivity of the insulation ensures reduced energy loss and running costs for a life time. The 3-in-1 construction keeps installation time to a minimum.
