RectorSeal has introduced another innovative product to its Safe-T-Switch product line: The patent-pending SSW Multipurpose Water Sensor. With no moving parts to break or become clogged, the SSW Water Sensor is placed directly into a metal or plastic secondary drain pan or on a floor. The SSW’s logic circuit continuously samples the sensor probes for the accumulation of water and determines if its presence is transient or permanent. When proprietary sensors detect as little as 1/16-inch of permanent water, the SSW Water Sensor automatically shuts off the HVAC system. A red LED on the unit’s top cover indicates that the SSW has been activated. The SSW Water Sensor is designed to automatically reset after the water has cleared.
