RectorSeal® Corp., Houston, a manufacturer and U.S. distributor of HVACR products, has introduced a line of Engineered HVACR products to design professionals through a nationwide network of bid/spec manufacturer's representatives.

Designated portions of three RectorSeal product lines — Big Foot Systems, SlimDuct, and Aspen Pumps — will be marketed through bid/spec reps in the United States. The brands' more standardized, shelf item products will continue to be sold through traditional HVACR wholesale distribution channels, according to Gerry Spanger, director of HVACR engineered product sales.

"The products accommodate discerning engineers and architects that design projects all the way down to equipment mounts, lineset ducting, condensate pumps and all the other basic accessories which ensure a professional, high-performance installation," said Spanger. "If basic accessories aren't specified, the installer chooses products and methods based solely on price, or omits them altogether, which results in poor aesthetics and/or equipment performance that ultimately affects the engineer's reputation."
