Up until now, the two biggest challenges with cold storage doors have always been weight, and complications with operation. These doors are known to freeze shut, thus increasing the precious time and effort required to access the critical environment of your temperature controlled containers. Heavy cold storage doors also cause energy drain on both automatic door operators and personnel alike, they contribute to lower operating speeds and longer exposure time.
Increasing exposure time causes the system to work much harder to maintain a safe temperature threshold, and also requires much longer reset times to compensate for thermal transfer. Longer reset times will often leave your personnel standing outside, waiting to enter or exit your temperature controlled containers. The worst case scenario is that exposure times get too high, or personal is shut out for too long, temperatures can rise to dangerous levels beyond the capacity of your system to compensate in a timely fashion. This is not an option for facilities entrusted to the storage of medical vaccines, ready to eat foods, and other highly temperature sensitive inventory. Any break in the cold chain can result in spoilage of an entire freezer, and an entire facility’s supply can be ruined. Subtle energy drains due to the amount of torque required to move the doors and the longer reset times also result in higher energy cost over time as well. [...]
