Composite pipes
The white Danfoss FH composite pipe is 100% impervious to air, temperature resistant and highly flexible. It consists of an aluminum pipe which is covered inside and out with a Polyethylene (PE-RT) layer. All layers are permanently bonded with each other through a layer of adhesive.
The octene side chains of the molecular structure of the PE-RT give it a similar effect to that of the cross-linked PE, which provides excellent Long Term Hydrostatic Strength at high temperature without crosslinking the material.
The Danfoss FH composite pipes are manufactured in such a way that the aluminum layer prevents the pipe from going back to its original form. This makes the pipes easy to install and the aluminum core ensures a long lifetime of your floor heating installation due to oxygen tightness.
The Danfoss FH composite pipe is used, in accordance with ISO 21003
PE-RT pipes
The Danfoss PEXa pipe is a high quality floor heating pipe with an EVOH oxygen barrier. All layers are permanently bonded with each other during the production process. PEX-a (peroxide) pipes give greater flexibility than PEX pipes cross-linked by other systems. They can be cold bent and curved very easily and without special tools, saving joints and installation time. The EVOH oxygen anti-diffusion barrier is a thin layer of ethylene vinyl alcohol copolymer which prevents permeability of the pipe to oxygen diffusion. This construction eliminates problems with addition of oxygen to the flow water and the resulting corrosion of metal parts in the installation, extending the working life of the whole installation. 5-layer piping made of cross-linked polyethylene and produced by the peroxide method, with oxygen anti-diffusion barrier, according to the requirements of European standard EN 1264-4. Pipe cross linking degree >70 % according to ISO 15875.
