HOUSTON–RectorSeal® LLC, Houston, a manufacturer and distributor of quality HVAC/R products, has introduced the RectorSeal HVACR (RSH) Series of surge protective devices (SPD), the industry’s only surge protection product line designed specifically for HVAC/R equipment that carries a lifetime warranty. The permanently-installed RSH Series is designed to protect all single phase, 120/240-V air conditioning, heat pumps and ductless mini-split systems (DMSS) from transient over-voltage and natural-cause surges.

Besides a lifetime product warranty, the RSH-50 and RSH-60 also surpass competitors’ connected equipment warranty by two years with an unprecedented five-year/$5,000 and five-year/$7,500, respectively, if the HVAC equipment is surge-damaged.

Both models use diagnostic LED lights. The RSH-50’s LED glows green to indicate operational status. The RSH-60 also has a green LED, plus a red LED and an audible alarm if the SPD is no longer providing protection.

The RSH Series is weather-rated under NEMA 4X and can be installed within minutes to the nearby outdoor disconnect box’s knockout access with an included 1/2-inch (12.7-mm) nipple and wired to the contactors. The RSH-50 can also be mounted inside the condenser with an included stainless steel bracket and wired directly.
