RAUVITHERM

REHAU RAUVITHERM is a pre-insulated PE-Xa pipe available in UNO 25-160mm and DUO 25-63mm. Due to its low weight and high flexibility, RAUVITHERM is fast and easy to install. Connections (both tees and straight) use the RAUVITHERM shroud system, filled with highly insulating PU foam to ensure minimal heat losses at the pipe joints. RAUVITHERM also has a 5 year product warranty as standard.

Materials

RAUVITHERM district heating pipes consist of carrier pipes (PE-Xa) with a primer and oxygen diffusion barrier (EVOH), insulation made from cross-linked, closed-cell PE foam sheet (λ = 0.043 W/mK) and a PE foamed corrugated ou- ter jacket to increase the ring stiffness and flexibility. In the case of DUO pipes, the location of the two carrer pipes in relation to each other is determined by extruded foam made of PE.

Benefits

Flexibility for easy installation - Excellent flexibility due to corrugated outer jacket and closed cell insulation. Allowing for rapid installation and the ability to easily navigate over or around obstacles on site.

Robust HDPE outer jacket - to withstand demanding onsite conditions.

Size flexibility - Long coils of up to 300 metres are possible, allowing for faster and more cost-effective installations. Longer coils mean fewer accessories and connections, reducing parts and labour, the risk of leakages, and the time to install.

Excellent insulation - High insulating performance from closed cell cross-linked PE foam minimises heat loss.

Fully sealed design - The outer layer of foam is bonded to the outer jacket to prevent water ingress.

Leakproof - Uses leakproof REHAU Everloc compression sleeve technology.
