What Is a Refrigerated Display Case?

Refrigerated display cases are everywhere—but what are they? CHINENG explains.

They chill and display foods and medicines—common for dairy, meats, produce, drinks, and plated dishes in hypermarkets, convenience stores, and hotels.

Working principle

Compressor refrigeration: a motor drives the compressor; low-boiling refrigerant absorbs latent heat as it evaporates. Long life and convenient use are advantages.

Advantages

1. Food-grade stainless about 0.5–0.8 mm thick and quality copper evaporator coils formed to wide profiles.

2. Smooth, even plates look solid and last longer.

3. Copper cools better and resists corrosion better than aluminum or composite tubes; clean coils and fewer joints reduce leaks and blockages.

4. Flattening round tube to rectangular contact turns point contact into surface contact for faster cooling.

5. Built for chilled display and sales of foods and medicines.

Freshness is the core job of a refrigerated display case.
