Alfaidro pre-insulated fittings are used for the distribution of high-temperature fluids and refrigerated fluids ensuring high levels of thermal insulation. The inner carrier pipe, also called service pipe, is a Faser multilayer PP-R pr PP-RCT reinforced with glass fiber, entirely surrounded by polyurethane foam insulation (PUR) and protected by an outer HDPE black sheath UV resistant.
All these features make this system ideal for transporting thermal and refrigeration energy over long distances from thermal power plants, heat pumps, geothermal plants, thermal plants, chillers, etc.
