"Put your frozen and medium temp equipment under your stringent control."

The ControlTec AS-20 uses a revolutionary dew point sensor to control Anti-Sweat heaters in glass display doors. Instead of running these heaters 24 hours a day, seven days a week, we can determine when they will condensate and automatically turn the heaters on before condensation begins and back off again when not needed!
