Local and district heating
Stations consist of many components such as pipes, elbows, fittings such as ball valves and control valves, pumps and many more. Our DH system has been specially developed for this variety of shapes. The range comprises 6 shapes each for the socket and flange area as well as pipes and bends in nominal widths DN15 to DN125.
The material of the DH system is uncoated black rigid polyurethane foam, which can be used at temperatures of up to +130°C. At higher temperatures, you should use a more highly cross-linked polyisocyanurate rigid foam, which is available via the AL system.
The sheathed insulation makes installation and adaptation to the station components very easy. The material is easy to saw, drill and carve. Pipe passages, spindle openings, pipe outlets and drains are quickly made. We recommend insulating the fittings of the station first, then the bends and finally the open pipe sections.
Our technicians will be happy to answer any questions you may have. We also organize workshops for processing this system. If you are interested, please get in touch with our sales contacts.
