Most cooler doors have built-in heaters that are designed to keep condensation from forming. These heaters run unnecessarily 100% of the time. Glass Sentry monitors environmental conditions in the store as well as door temperature to eliminate condensation without wasting energy by switching on the heaters only when needed. Glass Sentry pays for itself in just a few months!

There are a number of energy savings alteratives for the typical C-store to consider. The real difficulty lies in trying to find the best alternatives. Every company will try to push their system and justify their numbers in order to get the sale. Bottom line is that if it isn't feasible for the store in the first place, then it really isn't a solution at all.
