High-Quality Materials

Excellent Thermal Resistance
All insulated tube and pipe products are fabricated with high grade insulation with a thermal resistance up to 120°C.
Wear Resistant Outer Covering
Tough embossed outer covering is easy to tape and prevents damage during installation.
In addition, PE foam has good pressure resistance and it's not easy to be teared, especially at the hanging point.
Wear Resistant Outer Covering
Applicable to New Refrigerant “R32”!!
※Some of limited size are non-applicable.

Upgrade Working Efficiency

Improved Installation Efficiency
Easy to bend and cut, Paircoil (PC) can easily be separated by hand. No tools or cutting are necessary.
Length Markings
For 20m & 30m Coil, consecutively numbered length marking are clearly printed at 1 meter intervals on insulation surface to indicate remaining length.
Length Markings

Concealed Installation
For concealed pipe installations, thicker insulation types (20mm/25mm) are available to further reduce sweating.
