The RD-Series (rectangular metal) and Series PD-Series (round PVC) are enclosure solutions for protecting multiple linesets in the rooftop VRF system market.
The RD-Series comprises roll-formed rectangular sheet metal lineset duct and fittings. It features a proprietary, anti-corrosive, and chromium-free ZAM coating (Zinc, Aluminum and Magnesium). Based on a 3/8 x 3/4-inch lineset with 1/2-inch insulation on both lines, the series features: RD-300, RD-450, RD-600 and RD-900.
The PD-Series of weather-resistant PVC lineset enclosures can stand-alone use on smaller projects, or be a complementary transition piece. It’s available in three sizes–the PD-90–3.5-inch diameter; PD-120–4.7-inch diameter; and PD-140–5.5-inch.
