Pre-insulated copper pair coil with fire retardant insulation, for split and ducted air conditioning line sets in commercial, multi-residential and apartment work where a fire retardant lagging is specified. A liquid line and suction line are individually insulated and joined in one roll, so the pair runs out together and installs in a single pull.
Available with 9mm, 13mm or 19mm insulation thickness. The thicker options give better condensation control and thermal performance on long runs, in ceiling spaces and in humid conditions. The copper is annealed refrigeration grade tube to AS/NZS 1571 with wall thicknesses suited to R410A system pressures.
