Uponor MLC multi-layer system

Uponor MLC multi-layer system - an innovative solution for modern installations

The Uponor MLC multi-layer system is a breakthrough solution in the field of sanitary and heating installations.   It combines the advantages of plastic and metal, providing exceptional durability and flexibility.   At Onninen we offer a full range of products from this line. Our customers value them for their reliability and ease of installation.

MLC pipes consist of five layers. The aluminum core is surrounded by layers of polyethylene. This construction guarantees dimensional stability and corrosion resistance. The system works well in both new buildings and renovations. We often use it in apartment buildings and office buildings.

Key Elements of the Uponor MLC Multi-Layer System

The system consists of various components. The base is white MLC pipes with diameters of 16-110 mm. You can also choose from Uni Pipe Plus pipes 16-90 mm. For demanding applications, we recommend Uni Pipe Plus insulated pipes 16-25 mm. They are supplemented by connectors and fittings:

• S-Press elbows 16-63 mm
• PPSU elbows 16-63 mm
• S-Press Adapters 16-20mm
• S-Press wall elbows 16-25 mm
• Bellows valves DN 50 PN 16

All system elements are compatible and create a coherent whole.   This ensures tightness and trouble-free operation for many years. In our practice, we rarely encounter failures of these installations.
