Keeping a commercial HVAC system up and running efficiently can take a lot of work. But there are products on the market that ensure the system is functioning as it should by watching and directing system operation. The AquaGuard AG-3180E Plenum Rated Micro Pan Sensor by Resource Conservation Technologies is one such product that monitors what is occurring with the HVAC system and takes action when there’s a problem.

The condensate sensor is mounted directly in the primary drain pan, which, said Tammy White, inside sales manager, Resource Conservation Technologies, makes it ideal to be used with commercial package units. The bonus secondary sensor features water detection LED and easily installs in the metal or plastic secondary drain pan. Both sensors continuously monitor any condensate overflow in the primary and secondary drain pans and automatically shut off the system and activate an alarm if any overflow is detected in as little as 1/16 inch of water in either drain pan.

White said the company researched the product for two years, and some of the company’s most active contractors and customers tested and approved it.

Contractor-Friendly Features

While the pan sensor is designed to perform various functions, the company also designed features that make a contractor’s job easier, too. The low-profile design of the primary and secondary sensors make installation easier in tight commercial or residential spaces, said White.

Another feature that makes installation easier, said White, is that “The micro sensor features fully adjustable mounting clips that can be set at any desired condensate overflow height in the pan. The technician has flexibility for each installation and type of unit using the AG-3180E.”

Thanks to the secondary sensor mounting bracket, that sensor can be mounted in multiple ways and offers ease in cleaning and/or drying of the bonus sensor, said White.

Dale Vernatter, comfort advisor, John C. Cassidy Air Conditioning Inc., Riviera, Fla., agreed the product is easy to install and said it is reliable as well.
