How do supermarket display cases solve the problem of fogging, especially in high humidity environments, to maintain visibility and aesthetics?

There are several common strategies that can be used to solve the problem of fogging in supermarket display cases:

One technique is to apply a special anti-fog coating to the glass or plastic surfaces of display cases. These coatings prevent moisture from condensing, reducing fogging and ensuring proper visibility.

Many display cabinets are equipped with ventilation structures that help maintain airflow and reduce internal humidity. By controlling the humidity range, fogging can be minimized.

Some display cabinets include integrated heating elements, often placed close to glass or plastic surfaces. The heat generated with the help of these factors raises the temperature slightly above the dew coefficient, thus preventing condensation and fogging.

Well-insulated display instances effectively maintain the temperature difference between the inside and outside, reducing the potential for condensation. By keeping the housing surface oriented toward room temperature, fog accumulation can be avoided.

In some cases, primarily in very humid environments, a dehumidifier can be used to remove excess moisture from the air surrounding the display cabinets. This reduces the standard humidity levels within grocery stores, thereby reducing the likelihood of fogging.

These technologies are often used alone or in a mixture, depending on the unique design and functionality of the display case and the environmental conditions of the grocery store. By employing these strategies, supermarkets can ensure that merchandise is clearly visible and create an attractive purchase experience for customers.
