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 quick 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.
