Advantages of Multilayer Systems

Multilayer systems stand out for their efficiency and ease of installation in domestic water and heating systems.

High Resistance to Temperature and Pressure
: MT multilayer systems are designed to operate in cold water, domestic hot water, heating and HVAC installations with service temperatures of up to 95°C and working pressures of up to 10 bar. This capacity allows the system to be used in applications where thermal stability and mechanical strength are key factors in ensuring the safety and long-term reliability of the installation.
Lower Expansion and Greater Dimensional Stability
: The intermediate aluminium layer significantly reduces the linear expansion of the pipe compared with other conventional plastic systems. This helps maintain the shape of the installation without deformation, reduces mechanical stress and facilitates installation along long runs.
In addition, the shape memory of the multilayer pipe makes installation easier for professionals and improves the overall stability of the hydraulic circuit.
Protection Against Corrosion and Oxygen Diffusion
: The aluminium barrier integrated into the pipe prevents oxygen from entering the circuit, helping to protect radiators, manifolds, valves and other metal components of the installation. Unlike other materials, multilayer pipe does not suffer from corrosion, scaling or deterioration associated with continuous exposure to water.
Faster and Safer Installation
: MT multilayer fittings allow fast connections to be made using press or compression systems, reducing installation times and improving productivity on site. MT press fittings feature a double certified EPDM seal and stainless steel sleeves to ensure long-lasting leak-tightness, even under continuous operating conditions. To complete the system, MT offers manual pressing tools compatible with multilayer and PEX pipes from Ø16 to Ø32 mm, equipped with interchangeable jaws and compatible with the U profile. The range includes models with a rotating head and extendable handles, making work in confined spaces easier and allowing installations to be completed more comfortably, quickly and accurately.
Full Compatibility Between Components
: The MT range has been developed as a complete system in which pipes, fittings, valves and tools work together to ensure maximum compatibility and installation safety.
This simplifies both initial installation and future extensions or maintenance work.

Applications of the multilayer systems

Los sistemas multicapa MT están diseñados para trabajar en instalaciones de agua fría y caliente sanitaria, calefacción, climatización y redes hidráulicas de distribución.

Instalaciones de fontanería y agua caliente sanitaria (ACS)
: Multilayer systems are one of the most widely used solutions in plumbing installations for homes, residential buildings, hotels, educational facilities, and commercial buildings. Their resistance to pressure and high temperatures allows them to be used safely in cold-water and domestic hot-water systems. The low thermal expansion of multilayer piping facilitates installation in crawl spaces, suspended ceilings, and recessed runs, while the compatibility between fittings, valves, and piping helps reduce installation time and simplify future maintenance operations. Furthermore, as this system is approved for potable water, it is suitable for new construction, renovation, and comprehensive remodeling projects where a reliable installation capable of continuous use is required.
Radiator and Underfloor Heating Systems
: The MT multilayer system is designed for use in heating circuits subjected to high temperatures and continuous operation. Thanks to its aluminum barrier, it prevents oxygen diffusion into the system, helping to protect radiators, manifolds, valves, and other metal components from corrosion. Its dimensional stability and thermal resistance make it a suitable solution for radiator heating systems, single-pipe and two-pipe installations, as well as underfloor heating circuits where the reliability of connections is a critical factor. The availability of press fittings and specific valves allows for the configuration of complete heating circuits tailored to the needs of single-family homes, residential buildings, and commercial projects.
Heating, Ventilation, and Air Conditioning (HVAC) and Refrigeration Systems
: Multilayer systems are also used in HVAC and refrigeration systems where it is necessary to ensure stable performance in the face of temperature fluctuations and prolonged operation. The combination of multilayer piping, press fittings, and valves simplifies the installation of hydraulic circuits for HVAC systems using fan coils, terminal units, air-source heat pumps, and other hydraulic HVAC solutions. Its ease of installation, combined with the compatibility of its components, optimizes the assembly process and facilitates future expansions or modifications to the system.
Water Systems and Water Distribution
: The versatility of the multilayer system allows it to be used in water distribution networks within residential buildings, industrial facilities, commercial premises, and public facilities. The mechanical strength of the piping, combined with the reliability of the press and compression fittings, helps ensure uninterrupted service even in installations subject to heavy use. In addition, the wide range of multilayer valves, transition fittings, and connection solutions makes it possible to design complete hydraulic systems with a high degree of compatibility among components, facilitating both initial installation and long-term maintenance.

Frequently asked questions

What are the advantages of multilayer pipe compared with copper or plastic pipes?

Multilayer pipe combines the advantages of metal and plastic in a single solution. It offers lower expansion than conventional plastic pipes, corrosion resistance, protection against oxygen diffusion and faster installation using press or compression systems.

What types of installations are multilayer systems recommended for?

Multilayer systems are suitable for cold water, domestic hot water (DHW), radiator heating, underfloor heating, HVAC and hydraulic water distribution networks in homes, residential buildings, commercial premises and industrial installations.

Is multilayer pipe suitable for drinking water?

Yes. The MT multilayer system has certifications for use in cold and hot drinking water installations, complying with the requirements applicable to these types of applications.

Are MT multilayer valves and fittings compatible with different pressing profiles?

Yes. The Series 642 press fittings and valves are universal and compatible with TH, H, U and RFz profiles, making them suitable for a wide range of tools used by professional installers. The Series 647 press fittings and valves are compatible only with U and RFz profiles.

What is the difference between press fittings and compression fittings?

Press fittings create a permanent connection using pressing tools, allowing fast and secure installations. Compression fittings create a detachable mechanical connection, making them particularly useful for maintenance, repair or extension work on existing installations.

What tools are required to install multilayer press fittings?

To make multilayer press connections, pressing machines compatible with the fitting profile must be used. MT offers manual and automatic pressing tools for multilayer and PEX pipes from Ø16 to Ø32 mm, with interchangeable jaws and models featuring a rotating head to facilitate installation in hard-to-reach areas.
