Product Highlights

DiversiTech SOS-1 - Condensation Overflow Safety Switch

The SOS electronically senses water near the inside wall of the PVC drain tubing. By locating the SOS with its body away from the normal flow, it can be used to detect a possible overflow condition when the PVC drain line becomes full with water. The condensate drain line is normally mostly empty with a small amount of water flowing in the lower parts of the horizontal section. The sensor component of the SOS prevents false alarms by covering only part of the tubing, meaning a low volume of flowing water does not activate the switch.
