UNAVELD: Polyethelene, PERT-AL-PERT & 5 Layer Pipes

Suitable for sanitary and underfloor heating applications

UNAVELD pipes are manufactured in Germany and come with all the necessary certifications. They are suitable for water supply and heating systems (underfloor heating), solar and forced circulation systems, as well as for drinking water networks. UNAVELD pipe production process is certified according to DIN EN ISO 9002. Continuous research and development combined with a specialised personnel and high-tech manufacturing machines, ensure a lifespan of over 50 years.

Product Features

Hose Type50m & 100m coils

Hose MaterialPolyethelene, 5-Layered and Multi-Layered

Temperature Tolerance (°C)up to +100°C

Operation Pressureup to 20 bar

UNAVELD PE-RT Polyethelene Pipes

UNAVELD polyethylene pipes are manufactured in Germany from the high-quality primary material Dowlex. Dowlex is a polymerized ethyl octane compound with additional bonds, ensuring higher strength. Thus, greater strength and flexibility are achieved, as UNAVELD polyethylene pipes can withstand a pressure of 6 bar at + 95°C.

UNAVELD pipes are Type II and meet all requirements according to DIN 16833 / ISO 10508 for PE-RT. Manufactured from high density polyethylene (HDPE), this product offers long-term resistance to hydrostatic pressure and high temperatures.

Available in outer diameters of 15, 16, 18, 22, 28 and 32 mm, wall thickness of up to 3 mm in coils of 50 m and 100 m, as well as with protection thread in red or blue.

Benefits

  • Made in Germany
  • Manufactured from Dowlex
  • Radiation technology (RT) provides enhanced resistance to high temperatures and elasticity to thermal stress (thermal memory)
  • Increased elasticity compared to all other types of PE (PEx, PE-MD, etc.)
  • Dimensional accuracy and almost zero tolerances
  • Ideal for underfloor heating systems
  • Complete range of certifications
  • Warranty: 10 years

UNAVELD PERT-AL-PERT Multilayer Pipes

The Unaveld PERT-AL-PERT Type II multi-layered aluminum pipe consists of an aluminum pipe welded with the latest high-tech coating method on an inner and outer layer of polyethylene PERT (high quality Dowlex primary material) offering high heat resistance. All layers are firmly glued together using a layer of glue over the entire surface. The unique welding technique (TIG METHOD) guarantees high reliability, as the aluminum thickness is adjusted to meet the strength and flexibility requirements of a heating installation.

UNAVELD PERT-AL-PERT multi-layered pipes consist of the following layers:

PERT outer layer (ΡΕRT TYPE II)
PERT inner layer (ΡΕRT TYPE II) without colouring substances
Aluminum (AL) layered barrier
Adhesive Layer

Available in outer diameters of 16, 18, 20 and 26 mm, wall thickness of up to 3 mm in coils of 50 m and 100 m, as well as in long bobbins of 500m.

Benefits

  • Increased resistance to high temperature (up to +100°C) and pressure (up to 10 bar)
  • Excellent flexibility due to the new generation of polyethylene PERT (the high-quality primary material Dowlex)
  • Waterproof aluminum layered barrier
  • Prevents corrosion of individual parts/components
  • Tightness to oxygen diffusion
  • Shape Persistence: It keeps the formed shape, without recoiling
  • Reducing thermal expansion caused by temperature changes
  • No sediment accumulation
  • Thermal expansion similar to metal pipes
  • Material appropriate for drinking water
  • Easy, safe and quick installation. Needs fewer connection accessories
  • Lightweight and easy to use: 3 times lighter than copper
  • Excellent durability in time
