5-layer PE-RT technology for maximum performance
Underfloor heating tube
Our PE-RT (Poly Ethylene Raised Temperature) tube consists of five layers. The first and fifth layers are made of PE-RT type 1. The second and fourth layers are adhesive layers for attaching the third layer, the EVOH layer. This layer is located approximately in the middle of the pipe and ensures that the tube is impermeable to oxygen. This is in full compliance with the DIN 4726 standard.

Customised solutions in composite, stainless steel and steel
Manifolds
Our manifolds are developed and assembled entirely in-house. They are available in steel, plastic and stainless steel. The assembly process takes place for the most part on a fully automated, robotised assembly line. This enables us to guarantee consistent, high quality and high production output.
U-Tube Systems offers a suitable distribution solution for virtually every situation. Whether you need separate systems with heat exchangers (TSA) or hybrid distributors, we always provide a solution that fits your project.
In addition, we can engrave your logo using an integrated laser module to optimally express your brand identity.
