What advantages does it have over traditional cold cabinet doors? Invisible circuit, aesthetically pleasing; ultra-clear glass, no color difference and high transmittance, enhancing product presentation; safe low voltage, shock-proof; energy-saving, reducing manual wiping.
Who manufactures it? Dongguan Mingda Glass Co., Ltd., founded in 2007, with 19 years of specialty glass experience, holding 31+ patents, and participating in drafting the industry standard T/UNP 249—2024 "Electric Heating Coated Glass".
In the fresh food retail and cold chain display industry, fogging and condensation on cold cabinet glass doors have always been a pain point affecting customer experience and product sales. Leveraging 19 years of specialty glass R&D experience, Mingda Glass introduces the "Refrigerated Cabinet Glass Door Customization" service. We integrate invisible ITO conductive film heating technology into ultra-clear tempered glass, not only giving the cold cabinet doors automatic defogging and defrosting functions but also elevating the product display effect to a new height through high transmittance and minimalist frame design.
The product is widely used in supermarkets, convenience stores, fresh food stores, bakery shops, and pharmaceutical cold storage. We provide one-stop customization services from size measurement, hole design, voltage and power matching to frame material selection, helping commercial cold chain equipment manufacturers and end merchants create clear, beautiful, and energy-efficient display windows.
1. The "Face" Problem of Refrigerated Display Cabinets
Whether it is a beverage cabinet in a supermarket or a meat display cabinet in a fresh food store, the clarity of the glass door directly determines the customer's desire to buy. However, due to the huge temperature and humidity differences inside and outside the cabinet, traditional glass doors are highly prone to the following problems:
- Fogging and condensation: Water mist condenses on the glass surface, preventing customers from seeing the products inside and seriously affecting the display effect.
- Water droplet contamination: Condensate gathers and drips, not only soiling the products but also causing water accumulation inside the cabinet and breeding bacteria.
- Frequent wiping: Store staff need to constantly wipe manually, increasing workload and easily scratching the glass.
- Surging energy consumption: Ordinary glass has poor insulation, causing the compressor to start frequently and electricity bills to remain high.
Mingda Glass's refrigerated cabinet glass door customization solution is born precisely to completely end these industry pain points.
2. Core Technology: Making the Cold Cabinet Door "Heat" Itself
2.1 Ultra-Clear Tempered Substrate, Ultimate Transparency
Uses ultra-clear tempered glass with extremely low iron content, achieving a light transmittance of over 91%, with a pure base color and no green tint. Compared with ordinary float glass, it can more realistically restore the original colors of the products, making fresh meat, fruits, vegetables, and beverages look fresher and more attractive.
2.2 Invisible Conductive Film Heating and Defogging
A nanoscale transparent conductive film is integrated into the glass interlayer or surface. After power-on, the conductive film generates uniform heat, keeping the glass surface temperature always above the ambient dew point, fundamentally preventing water vapor condensation. The conductive film is completely invisible to the naked eye, without affecting the transparency and aesthetics of the glass.
2.3 Smart Low-Voltage Temperature Control
Uses 12V or 24V safe voltage power supply, with no risk of electric shock even if the glass is broken. Equipped with a micro temperature and humidity sensor, it automatically starts heating when humidity exceeds the standard, and automatically cuts off power when the set temperature is reached, saving energy and electricity, with extremely low daily power consumption.
Ultra-clear glass transmittance ≥91%, overall visible light transmittance ≥85%, heating power 80-150W/m², operating voltage 12V/24V safe low voltage, defogging time ≤3 minutes, service life over 10 years.
