Other Ways to Save on your Energy Costs
1) Purchase strip curtains for walk-in units to minimize the amount of hot
air entering the cooler.
2) Do not allow staff to leave cooler doors propped open for extended periods of time.
Remind employees to turn off the lights when they exit the walk-in. Not only do the bulbs waste energy when the cooler is empty, the lighting also produces heat which causes the unit to work harder to maintain temperature. In addition, try fluorescent bulbs in the cooler. They give off less heat and are more energy efficient.
Teach managers not to set the holding temperature too low on units because that will overwork the equipment. Walk-in coolers should be kept between 35 and 40 degrees and freezers between -5 and 5 degrees.
5) Make sure all cracks are properly sealed and replace worn gaskets.
Do not stack anything around the coil; this restricts airflow and decreases the performance of your cooler.
Have the defrost frequency set at minimum requirements (every four to six hours for 20 to 40 minutes depending on the amount of traffic in your walk-in).
With a little instruction, your staff can play a significant role in taking care of your valuable equipment. These simple precautions can save you a great deal of money in energy and service bills, help to avoid costly breakdowns during peak business hours, and extend the life of refrigeration units.
