Flexipipe 2 in 2 Insulated DN16

Our pre-assembled pipe systems with their high-temperature and UV-resistant insulation material are an ideal choice for your solar thermal system. The insulated double tube is a flexible, quick installation system to connect solar collectors to the pump station and to the storage cylinder. The system is lightweight and space-saving, which results in easy handling, even in confined spaces. Flow and return pipes are marked clearly and can easily be separated. Thus, collectors with a large distance between connectors can be connected quickly and economically.

2in2 is the way to reduce installation time whilst ensuring a leak-free installation. Two closed-cell elastomeric foam extrusions of high-temperature resistant EPDM are reliably protected against mechanical damage by a tough protective sheath.
