Chances are your walk-in is an absolute necessity. When one of your walk-ins goes down or is not temping, you can lose hundreds or thousands of dollars in product. The biggest problem is you don’t know there is an issue until it is too late. There are systems available that can notify you or your staff in real time when one of your units starts to warm up. Imagine: instead of finding a warm cooler and ruined product, you just receive an email or a notification on your smartphone to fix your walk-in before it’s an issue.
