At SHHAG, we believe that existing refrigeration equipment still holds great value when upgraded with the right technology. Instead of replacing complete cabinets, many supermarkets can improve efficiency, reduce operating costs, and modernize store presentation through professional retrofit solutions. Our latest old cabinet renovation project is a perfect example of how an open display refrigerator can be transformed into a more energy-efficient and attractive refrigerated merchandising system.
The customer was operating several open refrigerated display cases in a busy supermarket dairy section. These cabinets had been in service for years and were still structurally reliable, but like many traditional open coolers, they faced common operational challenges:
High energy consumption due to constant cold air loss
Unstable internal temperature during peak shopping hours
Increased compressor workload and maintenance pressure
Reduced product freshness caused by temperature fluctuations
Limited visual organization and less premium appearance
Higher sensitivity to store ambient temperature changes
The supermarket wanted a cost-effective solution that could improve performance without interrupting operations for a full equipment replacement.
After evaluating the cabinet dimensions and operating environment, our team proposed a custom old cooler upgrade by installing SHHAG manufactured glass door systems onto the existing open refrigerated cases.
The project included:
Precision measurement of existing cabinet structure
Customized glass door frame design
Tempered insulated glass doors
Self-closing hinge system
Slim profile handles
Magnetic gasket sealing system
Integrated LED lighting compatibility
Professional on-site installation support
By converting the open case into a closed glass door refrigerator, the supermarket gained the benefits of modern refrigeration technology while keeping the original cabinet body.
Before the retrofit, the display case was fully open, allowing cold air to escape continuously into the store environment. This caused unnecessary energy waste and made the cabinet work harder to maintain cooling temperatures.
After the installation of our glass doors, the entire unit was upgraded into a clean, modern, and highly functional closed merchandiser. Products remained clearly visible, while the cabinet could now preserve cold air more effectively and operate with greater stability.
The visual difference was immediate. The refrigerated aisle became more organized, more premium, and more attractive to customers.
One of the biggest advantages of adding glass doors to open coolers is reducing cold air loss. With doors closed between customer access, the refrigeration system runs more efficiently and uses less electricity.
Glass doors help maintain a more consistent internal temperature, which is especially important for dairy products, beverages, and fresh foods that require reliable cooling conditions.
Reduced energy use and less compressor strain can lower long-term operating expenses and extend the service life of existing equipment.
Clear glass doors create a structured, premium presentation. Customers can easily view products while the store benefits from a cleaner and more modern look.
Retrofitting old cabinets is a smart environmental choice. Instead of discarding usable refrigeration units, businesses can upgrade existing assets and reduce waste.
SHHAG specializes in refrigeration glass door systems for supermarkets, convenience stores, and commercial cold storage applications. Our solutions are designed for both new equipment manufacturing and old cabinet renovation projects.
We provide:
Custom sizes for retrofit applications
High-quality insulated glass
