Multi Calor Pipes



In the last ten years, aquatechnik in Sydney has been supporting the development of the multilayer technology, so to allow the introduction of the safety fittings.

The technology improvement has run over all the production phases, starting from the application of new adhesives that are more resistant to mechanical stresses, aluminium alloy plates with higher performances and easier to weld, up to the synchronisation of the entire process to assure maximum quality standards.

This new philosophy took the multi-calor composite pipes to the top of world classification, also thanks to the good balance between cost and quality.
The multi-calor pipes are classified according to UNI EN 21003, class 1; thanks to its high performances, the multi-calor is the only pipe system which can be used with the different ranges of aquatechnik fittings:

■ safety system (in PPSU – polyphenylsulfone) Available now, in Australia!
■ crimp-fitting (in galvanized brass and stainless steel)
■ com-press (in galvanized brass alloy)
■ valu-technik (heating-cooling radiant panel system, low temperatures)
The multi-calor pipes are also available in pre-insulated rolls.


■ great resistance to high working temperatures and pressures
■ chemical stability and safety to potable fluids for human consumption
■ no corrosive phenomena
■ reliability and long-time life of plants
■ malleability and ductility by manual processing
■ fluid flow-ability and lower pressure drops
■ lower thermal leakage
■ cheap installation and transportation to the working seat
■ impermeability to oxygenated fluids
■ simple and safe junctions
■ less processing waste.

The multi-calor pipes comprising of an inner layer of Pex-B can be used for all the hydro-sanitaryheating, conditioning systems and for installations with radiant panels and several applications more, allowing material saving.

Utilisation Fields

The multi-calor pipes are mainly used in the following fields:
house building:
■ conveyance nets, sanitation, heating, cooling and conditioning
systems, garden irrigation
■ conveyance nets and sanitation, heating and cooling systems,
compressed-air nets, power to hydraulic circuits of machine tools
services sector:
■ shops, laboratories, medical studies, schools, gyms, restaurants,
public utilities, hothouses, farms and so on.

Working Conditions

The multi-calor pipes can work by a max temperature of 95° C at 10 bar pressure (1,000 kPa), such as by low temperatures (less than 0° C), through the use of a special antifreeze, preventing icing inside of the pipes.

Time and money saving installations: thanks to their excellent mechanical characteristics the Aquatechnik multilayer pipes can be bent instead of employing fittings thus obtaining significant advantages from an economical point of view.Compared to metal pipes, Aquatechnik multilayer pipes have a greater resistance to chemical compounds and may undergo treatments (eg. super chlorination shock) for several years without being damaged.

Excellent flexibility: the combination of crosslinked polyethylene and aluminium guarantees excellent flexibility when bending (also when bent manually) and dimensional stability in the long term.

Reduced pressure loss: the extremely smooth internal surface, as well as preventing the formation of deposits such as lime scale, ensures reduced pressure loss also with the passage of time.

Guaranteed durability of at least 50 years: the system has guaranteed the durability of at least 50 years in compliance with product standards; in this period the product can be used at pressures of 10 bar and temperatures as high as 95°C.Barrier against oxygen and light: the butt-welded aluminium layer acts as a total barrier against oxygen and light, which in composite plastic pipes would otherwise favour algae growth and the corrosion of the metal parts that make up the system.

Lower thermal expansion: thermal expansion is approximately 8 times lower than all-plastic pipes and is similar to the expansion in metal composite pipes (It means that could easily replaces the copper due to the high performance stability and very low elongations).Non-toxic materials: the system is made up of materials that are completely non-toxic and is certified for the transport of consumable fluids and drinking water.

Light in weight: the pipes are extremely light in weight as compared with metal pipes: weight is 1/3 of a similar copper pipe and is 1/10 of a similar steel pipe.

The multi-calor pipes is produced with materials that can be completely recycled, which, at the end of their service life can be recovered. The production processes used are energy efficient and are of a low environmental impact; in terms of the environment and conservation of resources, the multi-calor pipes is in line with Green Building principles.
