Compatibility Everhot barrier PEX is compatible with the following systems listed by popularity: PEX with oxygen barrier offers an effective and low cost solution for protection of ferrous parts in hydronic and radiant heat systems against rusting and corrosion.Р В РІР‚СњР В РІР‚С›nother type of radiant heat tubing is PEX-AL-PEX. Without the oxygen barrier, only components made from non-corrosive material (such as stainless steel, brass, bronze) can be used in the system, subsequently increasing the costs of its initial installation and further maintenance. For cost reasons, many of components in a typical radiant/hydronic heating system - from circulator pumps to heating elements and piping of the boiler are either cast iron or ferrous and are subject to rusting when in contact with oxygen. The oxygen diffusion barrier coating of this radiant heat PEX prevents the oxygen in the atmosphere from permeating the pipe walls into the water to avoid over-saturation of the water with oxygen. More about Oxygen Barrier PEX Tubing The most common type of tubing used for radiant heat applications is the oxygen barrier PEX. The visual difference between these types is the glossy surface of the oxygen barrier PEX. This simple mechanism protects cast iron components of the heating system from rusting and contributes to higher operating efficiencies and longer lifespan of the parts. Non-Barrier PEXPrimary difference between Non-Barrier and Oxygen Barrier PEX is external coating of special polymer (EVOH), which purpose is to prevent gradual diffusion of O2 (oxygen) molecules into the water circulating in the heating system.
