Econofrost night covers for supermarket refrigeration
Field-proven retrofit that cuts energy, protects merchandise, and stabilizes cases
Econofrost night covers are designed for open refrigerated display cases in supermarkets, convenience stores, and food retail. The covers create a reliable thermal barrier that helps retain cold air inside the cabinet, keeps warm aisle air out, and shields products from harmful lights during non-trading hours. Retailers deploy them to lower energy use, reduce compressor cycling, and improve morning pull-down, all without replacing existing cases. The result is practical savings on utilities and shrink, plus steadier case performance across a chain portfolio. Core benefits documented by the brand include energy savings, shelf life support, outage resilience, and low total cost of ownership, which makes these covers an easy addition to corporate energy programs and store operating standards.

We help teams build the business of their dreams
Today’s retail food industry faces new and unprecedented challenges. freezer case night coverConcern for the environment and dwindling energy reserves means that energy costs remain consistently high. This is in addition to the demand for sustainable practices across the industry.
Retailers dealing with refrigerated goods utilize a great deal of energy as they attempt to extend shelf life and sustain the freshness and appearance of their perishable products.
Approximately 60% of a given retailer’s energy bill is devoted to the operation of its refrigeration system.
It is therefore both economically and environmentally beneficial for these businesses to adopt proactive measures in energy conservation.


Refrigerated display case night covers
How the thermal barrier supports vertical, island, and coffin formats
Open cases move a lot of conditioned air into the aisle whenever the store is closed, which forces refrigeration to work harder the next morning. Econofrost night covers limit that loss. By closing the case face, cold air circulates properly around the load while heat and harmful lights are deflected away. The effect is a steadier microclimate inside multideck vertical cases, island and coffin cases, and grab-and-go merchandisers used in grocery and c-store formats. Case temperatures see less drift overnight, compressors face less demand at start-up, and product appearance remains closer to “just stocked.” This simple mechanical control of air exchange is the reason night covers are a standard retrofit for retailers who must keep legacy equipment productive without capital-heavy case replacements.

Sustainable Technologies are Profitable Technologies
One of the most critical technologies available today is the use of reflective blinds over cold cases during closing hours. These nightshades keep essential refrigerated air circulating inside the display case while reflecting ambient light and heat away from the perishable product. This means that the temperatures within the refrigerated showcase remain consistent – prolonging the shelf life of the merchandise and maximizing profits.
In addition, these covers reduce the workload of the compressors and significantly lower the amount of energy consumed by refrigerated display cases.
Econofrost Covers an Industry Leader in Sustainable Technologies
Econofrost thermal curtains are a leading technology in the food retail industry. Only Econofrost blinds are made of a highly specialized woven aluminum fabric that is breathable, foodsafe, and durable.
Energy-saving refrigeration night covers
Measured reductions in kWh with smoother morning recovery
Third-party testing and brand documentation report meaningful electricity savings when covers are used consistently after hours. Southern California Edison testing found 36% energy reduction for every hour the covers were in use, and the product documentation notes cases can hold stable product temperatures long after opening, which eases morning recovery and reduces load spikes. Across a store, the accumulated hours translate into predictable utility savings and less run time on compressors and evaporator fans. These gains compound when covers are fitted to all major open cases in meat, dairy, produce, deli, beverages, and floral, making night covers a straightforward way to chip away at refrigeration’s outsized share of a supermarket’s bill.

Econofrost night covers can be installed or retrofitted in any size or model of refrigerated display case.
The covers are rolled down over the open surface of the showcase during closing hours and then discreetly retracted into their casings during operation hours. The thermal barrier remains, lasting up to 15 hours once the curtains have been rolled away.
Uncover The Benefits of Installing Econofrost Nightshades Today
By utilizing Econofrost aluminum shields, retailers will discover that less merchandise is damaged by temperature fluctuations and exposure to ambient light and heat. This means fewer discount, re-packaging, and discard costs for any retailer. Add to this an expected savings on every energy bill and it is clear that Econofrost refrigerator blinds are a wise investment for any refrigerated goods retailer.


Meat, dairy, produce, deli, and floral case night cover
Department-specific advantages that extend shelf life and reduce shrink
Departments that merchandise sensitive items benefit most from stable overnight conditions. Meat case night covers help limit discoloration and moisture loss that push shoppers away. Dairy case night covers maintain colder case air around milk and yogurt, supporting flavor and quality. Produce case night covers help greens and cut fruit retain appearance by reducing heat load and exposure to harmful lights. Deli case night covers preserve texture and color in sliced meats and salads, while floral refrigeration night covers protect bouquets from wilting so arrangements look sale-ready at open. The common thread is simple: less temperature drift and less light stress overnight means better appeal in the morning, fewer markdowns, and less trim labor.
Retrofit compatibility and product options
9000, 9600, XL, 7000, and 4000 magnet series for new builds and legacy cases
Econofrost offers several series so operators can match covers to case type and installation method. The 9000 retrofit cassette and 9600 non-cassette are widely used on multidecks and coffin cases. The XL Series is purpose-built for Hussmann INSIGHT and EXCEL models, while the 7000 Series and 4000 Magnet options provide additional mounting and service approaches for environments that need fast, clean installs. Model pages outline widths and drop lengths suitable for common supermarket case modules, and the OEM listing details simple field retrofit in many scenarios. This range allows chains to standardize across varied fleets without re-engineering fixture lines.


Materials and construction for retail duty
Woven aluminum on polyethersulfone, sealed for hygiene and long service life
The cover fabric is a woven aluminum laminated to a polyethersulfone backing and sealed with a polyethylene clear coat. This stack-up provides strength, hygiene, and flame spread resistance, with sealed edges that help resist dirt and stains and allow easy cleaning with mild detergent. The design is intended for daily cycles in high-traffic stores, with spring and brake assemblies that retract smoothly and withstand repeated use year after year. The materials choice is central to performance: aluminum reflects store heat and harmful lights, the backing adds durability in the food zone, and the clear coat simplifies sanitation, which together help the cover maintain its thermal function over long service intervals.
Power-outage protection and continuity
Rapid response that holds cold air in and buys time when it matters
When an outage or brownout occurs, a fast pull-down of night covers is a practical way to retain cold air and slow temperature rise. Econofrost’s guidance highlights a 3–6 hour window of added holding time when covers are deployed promptly, which can be the difference between salvageable inventory and a full loss. Case studies and brand posts describe incidents where stores avoided spoilage during extreme heat by closing cases with covers until power returned. For facility and ops teams, this becomes part of the response playbook alongside generator plans and temperature logging, and it can pay for the installation in a single event.


Sustainability and total cost of ownership
Lower operating cost today with measurable environmental gains over time
Night covers reduce the work refrigeration systems need to do, which lowers electricity consumption and equipment wear. Less energy use, steadier case temperatures, and reduced shrink tie directly to store P&L and sustainability metrics. The brand positions covers as a low-capital way to advance energy and waste goals while improving case performance, and the thermal-barrier function supports these outcomes by reflecting a significant portion of external heat and limiting air exchange at the case face. For chain operators who manage thousands of feet of open merchandisers, this retrofit scales cleanly across regions and case types and integrates with other conservation efforts.
