Refrigerated, low-temperature door cases have heaters in the door and door frames designed to keep condensation and moisture from the building and leaking onto the floor. As store temperature and humidity (dew point) in the store environment fluctuate based on climate zone and the time of the year, during closed periods, reducing the amount of time the heaters need to be on. Instead of simply running all the time, we can install controls to cycle these heaters on and off only as often as required to remove moisture. With the proper sensors and control components, you can put these savings in the bank, not your utility bill, and still have a safe store with no moisture condensation on your doors.
