By installing night covers on supermarket, deli, or cafe, vertical or semi-vertical display cases; you can reduce energy use due to reduced refrigeration, air conditioning, and heating loads.
The concept is straightforward. Insulated night curtains or retractable thermal shields are slid into place when the supermarket closes down for the night; preventing the refrigeration of the entire facility. This halts employees in these establishments from having to empty the contents of refrigerated cases, into the facility’s main coolers every night.
The energy savings is more than worth the cost associated with the procurement of the night covers themselves.
The installation of insulated night covers will dramatically increase the efficiency of vertical & horizontal refrigerated display cases.
The best known design of night covers consists of woven aluminum covers that can be factory installed or retrofitted onto existing display cases.
The back of the cover is coated with a fire retardant and the fabric is perforated for breathability and to prevent the accumulation of condensation. The aluminized night cover provides an insulated thermal barrier which is designed to be easily rolled up so they are out of the way when the store is open.
There are Secondary benefits associated with the use of aluminized night covers insulated covers including prolonging the shelf life and appearance of perishable products, reduced condensation, a tremendous reduction of produce losses due to drying and wilting, far less warming and melting, and added protection against short term power outages.
The use of aluminized night cover technology provides major savings in all grocery type stores where night covers are currently in use. These money saving covers, when installed correctly; can be deployed on meat, cheese, milk product, beverage, deli, floral, and produce coolers, coffin coolers, and display cases.
The use of night covers prevents warm air from infiltrating into the case, prevents cold air spillage, and reflects radiated heat away from the cooler. These features produce a money saving cooler with more stable case temperature; reducing daily produce trim and spoilage by as much as 75%.
American Traffic Doors installed 10 insulated aluminized night covers on meat, cheese, milk products, and beverage, deli, floral, and produce coolers; back in June of 2016 at a Trader Joes’ facility in northern California, who reported an average energy savings of 30% per month; per cooler; in a six month period of time.
One might think that in order to save allot of money; you have to spend allot of money. This could not be further from the truth. The fact is that when installed correctly; a standard four foot wide aluminized night cover can pay for itself in approximately two month’s time.
The entire concept of this item is to reduce the actual paid manpower who has been emptying the open refrigerated showcases and coffin coolers into the facility’s main walk-n or drive-in cooler; and letting the aluminized night cover do all the heavy lifting-so to speak. This is coupled with the night cover’s ability to keep the refrigerated food fresher, longer.
When it comes to refrigerated food items; and increasing compressor life by it not turn on as often; aluminized night covers prove to be a win, win scenario.
This goes along with the old statement: “Anytime you keep the cold in and the warm out; you save unbelievable money”.
Average Monthly Energy Savings as reflected on your monthly power bill, per refrigerated showcase or coffin cooler: 25-30%
