Save up to 80% on your Energy-Hungry Glass Display Doors

Proper Case Management is Easily the Lowest Hanging Fruit in Your Store!

It’s no secret that one of the largest operating costs in the supermarket industry is energy. In a typical store, refrigeration represents more than 50% of the energy used. A big part of that expense is the continuous operation of the anti-sweat heaters utilized by your refrigerated display doors, regardless of humidity levels, to prevent condensation.

Until Now…

Our patented dew point and frame temp sensors work together to provide continuous monitoring of humidity and temperature. By utilizing both of these sensors, the ControlTec AS-20z Case Manager System is able to pinpoint exactly when condensation will occur and adjust individual door heater cycles to prevent condensation before it starts.
