Instantor Pex-Al-Pex
Instantor Pex-Al-Pex
The Instantor PERT EVOH multilayer pipe is engineered specifically for underfloor heating and low temperature heating systems. Manufactured to UNI ES ISO 22391, the pipe combines the flexibility and thermal stability of PERT with a highly effective EVOH oxygen-barrier layer.
It’s 5-layer structure ensures excellent resistance to continuous heating cycles, reduced thermal expansion compared with standard single-layer plastics, and long-term reliability. The EVOH barrier prevent oxygen ingress into the heating circuit, protecting system components such as manifolds, pumps and valves from corrosion.
Key Features
Flexible Pipe
Lightweight yet robust, the pipe is designed to retain its shape after bending, allowing for quick installation and precise positioning.
Butt Welded Construction
Engineered with a seamless butt-welded finish, delivering exceptional strength and long-term reliability. Fully resistant to oxygen ingress and water vapour, ensuring system integrity.
Highly Durable
Built to perform under demanding conditions, withstanding continuous operating temperatures of up to 95°C without compromising performance.
Versatile Applications
Ideal for underfloor heating systems, potable water distribution, and a wide range of general plumbing uses
