IVAR Alpex Isol disc 20 x 2; 6 mm, 806341050

Product detailed description

This PEX-AL-PEX pipe is commonly used in residential and commercial buildings for domestic hot water (DHW) distribution systems. It is installed in radiant heating systems, underfloor heating, and central heating applications where thermal efficiency and long-term durability are essential. The pipe is designed for use in systems where the working temperature remains at +95°C continuously. Installers typically handle this product in new builds, renovations, and system upgrades, ensuring compatibility with existing fittings and system requirements.

The insulation jacket provides thermal protection and reduces heat loss, making it suitable for both heating and potable water systems. The cross-linked polyethylene (PEX) and aluminium layer ensure flexibility and resistance to thermal expansion, while the polyurethane foam insulation ensures a compact and efficient installation. The grey insulation jacket with a protective layer prevents mechanical damage and environmental exposure.

The operating temperature of +95°C and PN 10 pressure rating are key for determining the suitability of this pipe in DHW systems. These parameters ensure the pipe can handle continuous hot water flow without degradation. The insulation thickness of 6 mm contributes to energy efficiency and minimises condensation risk in unheated spaces.

Installation and connection

The pipe is connected using IVAR.TA or RA series fittings, or press fittings from the IVAR.PT or PPSU series. The connection process involves cutting the pipe to the required length, ensuring a clean cut, and inserting it into the fitting. A press tool is used for PPSU fittings, while TA and RA series use crimping or push-fit methods. It is essential to verify that the pipe is free from kinks and that the insulation jacket is undamaged before installation. Common mistakes include incorrect cutting, which can lead to leaks, and improper crimping, which can cause fitting failure over time. Always follow the manufacturer's guidelines for tool settings and connection procedures.

Compatibility and accessories

This pipe is specifically designed to work with IVAR.TA, RA, and PPSU series fittings. For press connections, the IVAR.PT series is also compatible. When planning an installation, ensure that the correct fittings and tools are available. Accessories such as pipe cutters, crimping tools, and press tools are required for a successful installation. No alternative products are listed for this model.

Technical background for designers

The PEX-AL-PEX construction combines cross-linked polyethylene with an aluminium layer, providing high flexibility and resistance to thermal expansion. The insulation jacket is made of polyurethane foam with a low-density polyethylene (LD-PE) protective layer, ensuring thermal efficiency and mechanical protection. This pipe is suitable for both heating and potable water systems. The service life and efficiency depend on correct installation, system pressure, and temperature conditions. The insulation thickness and material contribute to long-term performance and energy savings.

Service and operation

Routine maintenance is not required for this pipe, but periodic checks for leaks, insulation damage, or fitting loosening are recommended. Ensure that the system pressure and temperature remain within the specified limits. No specific service intervals are provided in the brief.

Frequently asked questions

Can IVAR Alpex Isol 20 x 2 be used for both heating and potable water?
Yes, this pipe is suitable for both radiator heating and drinking water systems, provided the operating conditions remain within the specified parameters.

Is it possible to order this pipe in smaller lengths than 50 m?
No, the IVAR Alpex Isol 20 x 2 is only available in 50 m reels. Smaller monosizes are not offered for this model.

What is the recommended connection method for this pipe?
The pipe can be connected using IVAR.TA or RA series fittings with crimping or push-fit methods, or with IVAR.PT or PPSU series press fittings. The choice depends on the system design and available tools.

Can this pipe be used with other brands of fittings?
It is recommended to use IVAR.TA, RA, PT, or PPSU series fittings for compatibility and system integrity. Using non-IVAR fittings may compromise the connection and system performance.
