3 or 5 layer EVOH PERT pipe for underfloor heating system,
3layer EVOH PERT size 20*2.0mm
5layer PERT EVOH PERT size 20*2.3mm
PE-RT with EVOH oxygen barrier pipe is composed of 3 or 5 layers,
the EVOH oxygen barrier can effectively prevent oxygen permeability
therefore eliminate bacteria growth inside the pipes to ensure
clean water and better sanitation, as well as prevent the metal
parts in the system from corrosion to ensure a much longer service.
