A common application use for Senasys snap disc thermostats is freeze protection. We received a new application from a car wash company, who need a way to insure their equipment doesn’t freeze. They need to make sure the temperature is high enough in the bill boxes and automated cashier to help with moisture removal and keep the touch-pad circuits warm. They also have to make sure that the CCTV camera housings aren’t freezing and the cameras are fog free.
