Emmeti PE-Xa Floor Coil Piping

Emmeti PE-Xa Floor Coil Piping

PE-Xa Floor Heating Barrier Pipe

Emmeti PE-Xa is a durable, quality plastic pipe ideal for use with In-Slab floor heating applications. PE-Xa holds its form and rigidity with good stiffness, making it ideal for use in slab and inscreed applications where the piping is attached directly to the concrete steel Reo prior to pouring and may be exposed to impacts during installation.

PE-Xa piping is made using simple three layer construction. This simple construction allows rapid heat dissipation to the slab. It has an inner layer of PE-Xa (Cross linked Polyethelene), an adhesive layer and then an outer oxygen barrier layer of EVOH (Ethylene Vinyl- Alcohol Resin). As slabs are heated to a lower temperature more rapid heat dissipation improves the efficiency of the system.

The outer EVOH layer prevents permeation of oxygen through the tubing which eliminates corrosion of the metal components in a heating system such as mixing valves, boilers etc.
