X-PERT S5 White Paper

 

Ultimate System Protection

The five-layer design ensures that the EVOH oxygen barrier is protected and remains intact, safeguarding your radiant heating system. X-PERT S5® comes with a limited lifetime warranty.

 

Unsurpassed Flexibility

X-PERT S5® saves you time and money even at low temperatures, which improves installation efficiencies.

 

Reduce pressure loss & deposit formation

Roth X-PERT S5® pipe has excellent smoothness.

 

Environmentally Friendly
Unlike any other heat pipe, X-PERT S5® is fully recyclable.

 

PE-RT pipes have been used in European markets for more than twenty years with exceptional results. Roth X-PERT S5® pipe is made with DOWLEX™ 2344 Polyethylene Copolymer Resin, which offers the traditional benefits of polyethylene resin along with excellent high temperature resistance. The result is the next generation of radiant heating pipe.

 

Roth X-PERT S5® pipe delivers excellent long-term hydrostatic design strength, without the need for cross-linking. This increases flexibility, resulting in potential installation savings. Roth X-PERT S5® also has excellent surface smoothness for improved flow properties and is produced using state of the art equipment .

 

The five-layer pipe consists of a layer of ethylene vinyl alcohol polymer (EVOH) sandwiched between two layers of Polyethylene Copolymer Resin and two layers of adhesive. This structure provides the outstanding long-term hydrostatic design strength demanded by hydronic heating applications. The outer layer of Roth X-PERT S5® also provides a protective shield for the oxygen barrier. This ensures that the radiant heating system has the best protection available against oxidation due to oxygen permeation of the piping system.

 

Roth X-PERT S5® pipe is the ideal choice for domestic and industrial radiant heating systems in North America.
