Innovative Solutions for Supermarket Refrigeration
Econofrost Night Covers and Promolux LED Lighting for Refrigerated Display Cases
Every supermarket relies on open display cases to attract shoppers, but those same cases also drive up energy costs and expose fresh food to conditions that shorten shelf life. At Supermarket Equipment Design, we supply two complementary technologies—Econofrost Night Covers and Promolux LED Lighting—that directly address these challenges. One focuses on saving energy and protecting cold air; the other ensures food looks the way it should while slowing the effects of harmful light.
Both products are used worldwide by retailers who understand that operational efficiency and product integrity go hand in hand. By pairing energy-efficient refrigeration solutions with lighting engineered for food safety, stores create a shopping environment that lowers costs and inspires customer confidence.
Econofrost Refrigerated Display Case Night Covers
Nighttime Energy Protection for Open Coffin and Multi-Deck Cases
When the lights go out at closing time, open refrigerated cases continue working hard against warm store air. Econofrost Night Covers were designed to solve that problem. Once pulled down, they form a shield that holds cold air inside the case, easing the load on compressors and cutting unnecessary energy use. Retailers typically report 37–50% lower refrigeration costs per hour of cover use, making Econofrost one of the most reliable energy-saving tools in food retail.
Unlike quick fixes, Econofrost covers are engineered for durability. They use strong, heat-reflective materials that perform night after night, across produce, dairy, meat, deli, beverage, and floral departments. For chains managing dozens—or even hundreds—of locations, the consistency of performance is just as valuable as the savings.
Why Econofrost Works
Temperature Stability and Reduced Product Loss
The secret to Econofrost is its ability to stabilize the environment inside a refrigerated case. By creating a thermal barrier, the covers slow down the impact of ambient heat and moisture, keeping temperatures closer to ideal storage conditions. The result is less product shrink and spoil overnight, especially in sensitive categories like meat and produce.
It’s not just about energy savings—it’s about operational security. Retailers using Econofrost find that their cases recover faster in the morning, equipment requires less maintenance, and food departments run with fewer interruptions. In an industry where downtime and product loss can be costly, that stability makes a measurable difference.
Econofrost Product Line
Flexible Options for Every Store Format
Every supermarket is different, which is why Econofrost manufactures a variety of cover designs. Cassette-style retrofits are a popular choice for stores upgrading existing cases without major modifications. Non-cassette models provide an affordable solution for smaller cases or independent grocers. For larger, multi-deck cases, motorized systems offer convenience and speed, while lockable models add security in high-traffic areas.
Each style is built to last, using reinforced materials and tested for daily commercial use. By offering a range of options, Econofrost gives retailers the ability to standardize energy-saving practices across every case type—without compromising fit or function.
Promolux LED Lighting for Refrigerated Displays
Lighting Designed Specifically for Fresh Food
Most LEDs are built for brightness, not for food. Promolux LED Lighting for Refrigerated Display Cases is different—it was developed specifically for supermarkets. Its high color rendering index ensures that meat, seafood, dairy, produce, and bakery items look exactly as they should: fresh, natural, and appealing. Customers see vibrant reds, crisp greens, and warm golden tones that inspire confidence in product quality.
Beyond appearance, Promolux also protects food. Standard case lighting often emits wavelengths of harmful light that accelerate oxidation, causing discoloration and premature spoil. Promolux filters out those damaging wavelengths, creating a safer lighting environment that both displays food attractively and helps extend shelf life.
The Promolux Difference
Balanced Spectrum Technology for Better Merchandising
What sets Promolux apart is its unique spectrum design. Instead of flooding displays with harsh or unfiltered light, Promolux uses a balanced spectrum that highlights natural color while minimizing damage. That balance keeps foods looking fresher for longer, reduces waste, and creates a more trustworthy shopping experience.
For store managers and merchandisers, the value is clear: better product presentation leads to stronger sales, fewer markdowns, and reduced product losses. By adopting food safe display lighting, retailers protect their inventory and their brand reputation at the same time.
