POLYMELT ECOSAN PIPES: THE IDEAL PIPE SYSTEM FOR HOT & COLD POTABLE WATER
POLYMELT pipes made of PP-R and PP-RCT are manufactured according to DIN EN ISO 15874, EN ISO 21003 and DIN 8077/78 and fulfil their quality requirements. Not only the ideal system for potable water but also for compressed air systems, agriculture and horticulture, Industries (e.g. transportation of aggressive media like acids, alkaline solutions, etc.), heating installations, shipbuilding and other media/applications upon request.
ECOSAN FITTINGS
The PP-R-metal connection of the ECOSAN fittings excels by its leakproofness and resistance to torsion. This connection withstands decades of operational loads without any difficulty. Thanks to the specific geometry of their inserts, which are made of high-grade brass, the moulded parts meet the highest safety standards and guarantee safe laying.
Applications of POLYMELT ECOSAN PP-R and PP-RCT pipe systems
The ECOSAN installation system fulfils a variety of demands made on supply lines. It is suitable for universal use in new buildings, refurbishment, repairs.
In drinking water installations for cold and hot water pipes in residential buildings, hospitals, hotels, office buildings, schools, etc., for example:
- Service connections
- Boiler connections
- Water distributing systems
- Rising lines
- Floor-level distribution
- Fittings
as well as piping networks for:
- Rainwater systems
- Outside pipe laying
- Compressed air systems
- Agriculture and horticulture
- Industries, for example the transportation of aggressive media (acids, alkaline solutions, etc.), taking into account its resistance to chemical agents
- Heating installations
- Shipbuilding
- Further media and possible applications upon request.
ECOSAN is not suitable for:
- Industrial gases
- Flammable liquids and gases
- Coolants/refrigerants
The POLYMELT ECOSAN piping system is suitable for:

Cold water

Hot water

Compressed air

Potable water

Note: heating element temperature 250 to 270 °C. Instructions for socket welding can be found in DVS brochure no. 2207, Section 11, “Socket welding with a heated tool – welding of thermoplastic plastics and pipelines made of polypropylene (PP)”. ECOSAN socket welding is performed according to these guidelines. In this process, pipes and fittings are welded overlapping. The end of the pipes and fittings are heated using a welding device and are subsequently connected. Please find all technical details in our technical manual.
