Variety of versions by in-house-manufacturing


EMPUR® manufactures a standard range of plastic heating pipes as PE-Xa and PE-RT in dimension of 10, 12, 15, 17, 20 and 25 mm. Other dimensions are available upon request.

The heating pipes can be used for floor heating, low-temperature heating, high-temperature heating and radiator heating as well as for connecting heaters.

KLIMAPEX® PE-Xa five-layer pipe

The KLIMAPEX® PE-Xa five-layer pipe constructed using the Engel process is a premium plastic pipe for harsh building site applications. The EVOH barrier layer is guarded against damage by the external PE protective layer.

Special characteristics and materials

  • Resistant against deformations and external influences as well as tension-crack formation
  • Robust and of exceptional quality, guaranteed by in-house production and control, as well as outside verification
  • High-pressure networked polyethylene in accordance with DIN EN ISO 15875; cross-linking degree >= 70% in accordance with DIN 16892
  • Safety advantage for a consistent temperature of +95°C, short-term excess temperature (max. 2 years) +110°C, operating pressure 6 bar
We also produce the KLIMAPEX® PE-Xa five-layer pipe in a hook and loop version in-house. 

KLIMAPEX® PE-RT five-layer pipe

The KLIMAPEX® PE-RT five-layer pipe is a premium plastic pipe for harsh building site applications. The EVOH barrier layer is guarded against damage by the external PE protective layer.

Special characteristics and materials

  • Resistant against deformations and external influences as well as tension-crack formation
  • Robust and of exceptional quality, guaranteed by in-house production and control, as well as outside verification
  • Polyethylene in accordance to DIN EN ISO 22391-2 an DIN 16833 with insoluble EVOH barrier layer as per the unique HP process
  • Safety advantage for a consistent temperature of +70°C, short-term excess temperature (max. 2 years) +90°C, operating pressure 4 bar
We also produce the KLIMAPEX® PE-RT five-layer pipe in a hook and loop version in-house.

KLIMAPEX® metal composite pipe PE-RT/AL/PE-RT

Our PE-RT/AL/PE-RT pipe is a premium metal composite pipe for the OPTIMAL II dry construction system.

Special characteristics and materials

  • Diffusion-tight according to DIN 4726
  • Resistant against deformations and external influences as well as tension-crack formation
  • Safety advantage for a consistent temperature of +70°C, short-term excess temperature (max. 2 years) +90°C, operating pressure 5/6 bar
  • Smallest bending radius 5 x d (d = outer diameter)
The KLIMAPEX® metal composite pipe is optimally matched to our OPTIMAL II dry construction system.
