PEX-AL.-PEX and PERT-AL.-PERT MULTI-LAYER FITTINGS

The heatPEX� multi-layer fittings are available in diameters from 16 to 63mm. The pipes can be used in multiple applications: central heating, underfloor and wall heating and hot/cold water systems. The pipes are highly resistant to pressure and temperature, wear, boiler scale, have minimum linear expansion, are resistant to oxygen diffusion, low weight, high plasticity and are easy to install.

Complete heatPEX� system comes with high quality clamp couplings made of brass resistant to dezincification . The system is pressed using TH type jaws.

PEX-a PIPES /Dz 16 mm - Dz 160 mm/

he heatPEX� pipes are applied in internal fixtures in the diameter range from 16 to 160 mm. The pipes are made of PEX-a cross-linked polyethylene, modified using Engel�s method. PEX-a pipes are available in the following types:

saniPEX pipe PN10/95°C, SZEREG SDR 7,4
heatPEX pipe PN6/95°C, SZEREG SDR 11 / with EVOH anti-diffusion barrier.

The pipes are mainly used in connecting individual apartments to divider fixtures, for underfloor heating, for risers and horizontal fixtures.
