The walk-in freezer or cooler is the heart of every supermarket, restaurant, and convenience store. Temperature control of your perishable items is the key to providing customers with a safe, delicious product. However, refrigeration and cooling costs can quickly inflate your electricity bill, especially in areas with high temperatures. While new models come equipped with features that enhance productivity, many businesses continue to use well-worn, older models that have served them adequately in the past. Thankfully, there are many ways to ensure that your current walk-in freezer or cooler is operating with maximum efficiency.
1. Night Covers
Adding covers to open cases will trap refrigerated air, keeping the product much colder for longer periods. In fact, night covers reduce electricity use by up to 40 percent, and temperatures will remain much colder even after the covers are removed.
2. Strip Curtains
Adding strip curtains to your walk-in cooler will keep cold air in and hot air out, allowing people to move in and out with as little temperature disturbance as possible. This will greatly reduce the strain on the compressors while extending product shelf life by up to 50 percent.
3. Fluorescent Lighting
Another way to help increase the efficiency of your freezer is to replace incandescent bulbs with fluorescent lights. Incandescent lighting generates heat and is far less effective than ENERGY STAR compact fluorescent lamps (CFLs). Switching to CFLs can reduce energy use by 75 percent.
