Rauthermex 160mm/250mm Uno Pipe - Rehau

Rauthermex 160/250mm UNO Pipe

RAUTHERMEX is a pre-insulated PE-Xa pipe for district heating, biomass, biogas and heat pump applications. The high performance PU foam makes it ideal for large district heating over long distances where heat losses are critical. Lightweight polymer pipes such as RAUTHERMEX offer huge advantages over traditional steel pipework due to the speed and ease of installation.

The RAUTHERMEX pipes are made of high-pressure cross-linked polyethylene (PE-Xa) in accordance with DIN 16892/93, SDR 11 with an EVOH oxygen diffusion barrier in accordance with DIN 4726. The thermal insulation is made of polyurethane (PU) and the outer jacket is made of polyethylene – low density (PE-LD).

The excellent thermal insulation properties of the polyurethane foam insulation and the corrugated outer jacket make RAUTHERMEX a pipe system that keeps losses during heat transport particularly low, without lacking a high degree of flexibility.

RAUTHERMEX is available in UNO 25-160mm and DUO 25-63mm and is suitable for the following applications:

• Local and district heating
• Biomass boiler connections
• Industry and agriculture
• Ground-source and air-source heat pump connections
• Swimming pools
• Cooling equipment and ice rinks
• Outdoor facility heating

The many advantages of RAUTHERMEX pipes include:

• Excellent thermal insulation with PU foam with a lambda value of 0.0216W/mK
• New 140mm UNO is the largest polymer flexible district heating pipe on the market which can transport up to 2.5MW of heat at 80°C/50°C flow & return temperatures
• No need to compensate for thermal expansion due to bonded foam structure
• Long coils up to 570m possible, allowing for faster installations vs steel system in 12m lengths
• Uses the renowned leak-proof REHAU EVERLOC™ compression sleeve technology, used over 850 million times
• Generation II shrouds are quick and easy to install and remove the need for hot works on site.
