PURMO CLEVERFIT PE-RT/AL/PE-RT pipe with insulation 16x2 50 m/coil FRBC1620050PXR06

Multilayer pipes for heating and plumbing systems

PURMO CLEVERFIT PE-RT/AL/PE-RT pipe with insulation is a versatile solution for constructing heating and plumbing systems. The pipe’s construction, based on a combination of heat-resistant polyethylene (PE-RT) and an aluminum layer, ensures high durability and reliability. The aluminum layer prevents oxygen ingress, minimizes thermal expansion, and allows the pipe to retain its shape after installation. An additional bonding layer between the aluminum and polyethylene prevents delamination, enhancing the overall longevity of the structure.

These pipes are highly flexible, facilitating easy installation and adaptation to complex piping layouts. They are designed for use in radiant heating systems (e.g., underfloor and wall heating) as well as traditional central heating and plumbing installations. The pipes hold a PZH hygiene certificate and DVGW certification, confirming their safety and compliance with applicable standards.

Construction and Properties

The pipe consists of five layers: two outer and inner PE-RT layers, two adhesive layers, and a central longitudinally welded aluminum layer. This construction provides the following advantages:

• High-temperature resistance: Maximum operating temperature is 95°C, with a short-term maximum of 100°C.
• Pressure resistance: Withstands working pressure up to 10 bar.
• Oxygen barrier: The aluminum layer effectively prevents oxygen diffusion into the system, protecting metal components from corrosion.
• Low thermal expansion: Minimizes dimensional changes due to temperature fluctuations, ensuring system stability.
• Flexibility: Simplifies installation and adaptation to existing infrastructure.
• Hygienic properties: Materials used are neutral to potable water and resistant to chemicals, including glycol (up to 30%).
