RectorSeal Offers HVAC/R Industry's
Only Commercial Rooftop Lineset Protection Duct.
Slimduct RD-Series and PD-Series Lineset Ducting Systems
offer the most aesthetic and economical method to protect
multiple linesets used on HVACR equipment.
Corp., Houston, a leading manufacturer and U.S. distributor of
quality HVAC/R products, introduces the SlimDuct RD-Series and
the PD-Series, the world's only commercial rooftop ducting and
support systems that are designed exclusively for multiple
linesets as used with variable refrigerant flow (VRF)
multi-split systems or any other conventional air-conditioning
and refrigeration systems.
The RD-Series and PD-Series are the most practical, economical,
durable and professional solutions for protecting the multiple
linesets commonly used on rooftop VRF systems, a mature industry
in Asia which is quickly emerging in North America. Both series
save more than 75-percent in labor when compared to the
alternative of custom-fabricated galvanized sheet metal lineset
ducting or other labor-intensive fabrications.
The RD-Series comprises 20-gauge, roll-formed rectangular sheet
metal lineset duct and fittings. It features a proprietary,
anti-corrosive, scratch-resistant hot-dipped and chromium-free
ZAM® coating (Zinc, Aluminum and Magnesium) that provides a
superior, more durable and lighter weight alternative to
galvanized steel. Widths for the RD-300, RD-450, RD-600 and
RD-900 are 12, 18, 24 and 36-inch respectively and all are
5-1/8-inches high. Based on a 3/8 x 3/4-inch lineset with
1/2-inch insulation on both lines, the RD-Series can accommodate
the following number of linesets: RD-300 (8), RD-450 (12),
RD-600 (19) and RD 900 (25).
The PD-Series is designed for smaller installations which do not
warrant the larger metal lineset duct. It also serves as a
transition to protect the lineset from where it exits the VRF
condenser until it enters the RD-Duct. The PD-Series differs
from the RD-Series in that it consists of UV, fire and
weather-resistant ivory-colored extruded PVC round duct in 2
sizes only, PD-90 (3.5-inch diameter), & PD-120 (4.7-inch
diameter), and is available in 39 inch & 60 inch lengths.
Because of its sleek profile, smooth surface and neutral color,
the PD series is perfectly suitable for use indoors to conceal
and protect unsightly exposed linesets, drain lines and cables.

Similar to the
RD-Series, each size comes with a selection of fittings, 90 & 45
degree ells, couplers, tees, wall flanges, end caps and mounting
brackets which can be customized to suit any lineset configuration.
Other features of the RD-Series and PD-Series include:
· According to third-party tests performed by the Building Center of
Japan and Japan's Civil Engineering Research Center, the RD-Series
is certified more corrosion-resistant than galvanized steel.
· Both series carry a two-year warranty.
· Both series can also be used vertically or horizontally to protect
linesets associated with any air conditioning, refrigeration or
industrial cooling process equipment.
· RectorSeal offers free design services through their Japanese
trained technical support personnel.
· On rooftop systems when the top of the RD-Series duct (Type RWK)
has to be used as walkways, a reinforced heavier gauge cover plate
with a non-skid surface is available as a special order option.
· RectorSeal stocks the full range of PD-Series as well as the
RD-300, RD-450, & RD-600 sizes. The RD-900 size is available only on
· The RD-Series is available only through RectorSeal’s network of
accredited bid/spec representatives. The PD-Series is also available
through these bid/spec reps, however it is also freely available
through most wholesale HVAC/R distributors.
