In modern retail, the visual presentation of a product plays a decisive role in the buyer’s purchasing decision. That is why the question of what is the name refrigerator display casebecomes relevant for entrepreneurs opening grocery stores, cafes or confectionery shops. In the professional environment and technical documentation, this equipment is often called simply refrigerated display case or refrigerated display case, however, there are many specific names depending on the design and purpose.
The main function of such a device is not only to preserve the freshness of products at low temperatures, but also to effectively demonstrate them. Commercial refrigeration equipment it should provide ideal temperature conditions, while simultaneously allowing the client to see the product from all sides or from the most advantageous angle. There is a division into low-temperature models for freezing and medium-temperature models for refrigerated products, which directly affects how a specific piece of equipment will be called in the supplier’s catalog.
Understanding the correct terminology helps to avoid mistakes when purchasing equipment for a store. If you ask a consultant for “freezer,” you will get the wrong device for displaying deli meats on the counter. In this article we will look in detail at how equipment is classified, how different types differ showcases and what technical nuances you should pay attention to when choosing.
Main types of commercial refrigerated display cases
The first thing you need to know is everything refrigerated display cases are divided into two large groups according to the method of access to the product: open and closed. Open models do not have doors or glass partitions at the front, allowing easy access for customers. Such devices create an air curtain that keeps the cold inside the work area. They are ideal for high-traffic supermarkets, where it is important that the customer can quickly take the desired product.
Closed display cases are equipped with glass doors or lids. This solution allows you to significantly save energy and better maintain temperature, since cold air does not mix with the warm air of the sales area. Closed models often used for storing expensive goods, delicacies or products that require strict adherence to temperature conditions, for example, children's dairy products or chilled fish.
⚠️ Attention: When choosing between open and With a closed model, take into account the humidity in the room. Open display cases can form condensation on the floor in very humid rooms if the moisture removal system does not cope.
In addition, there is a division according to temperature conditions. Medium temperature showcases (from 0 to +10°C) are intended for gastronomy, sausages, cheeses and drinks. Low temperature (up to -18°C and below) are used for frozen semi-finished products, ice cream and deep-frozen meat. The wrong choice of type can lead to damage to the product or breakdown of the compressor.
- 🛒 Open slides is a popular type for self-service in supermarkets.
- 🚪 Closed cabinets — provide better insulation and protection of the product.
- ❄️ Lari —horizontal freezers with a lid, often used for freezing.
- 🥩 Gastronomic display cases —specialized models for cutting and laying out meat products.
Design features and structure
When understanding what a refrigerator display case is called, you cannot ignore its internal structure. The basis of any unit is refrigeration unit, which can be built-in or remote. Embedded systems are compact and do not require complex installation; they are immediately ready for use after connecting to the power supply. Remote units are installed in a separate technical room and connected to the display case by pipelines, which reduces noise in the sales area and increases the cooling efficiency of large areas.
An important design element is heat exchanger the defrosting (defrosting) system. Modern models use automatic defrosting, which prevents the build-up of “fur” on the evaporator. This is critical to maintaining the stated temperature. The device body is usually made of stainless steel or galvanized metal with a polymer coating, which ensures durability and hygiene.
Particular attention should be paid to the type lighting. Showcases use special LED strips with a specific color temperature. For meat, light with a pink tint is used, for vegetables - with a green tint, and for baking - with a warm yellow spectrum. This is not just decoration, but a marketing tool that makes the product more attractive.
Why is a showcase humming?
The humming can be caused by the operation of the compressor, vibration of the tubes or improper installation. If the sound becomes sharp or a grinding sound appears, you need to check the compressor fastening and the absence of ice on the fan blades.
Classification by installation method
The dimensions and layout of the sales area dictate the choice of equipment installation method. The most common type is wall showcases. They are mounted close to the wall and take up minimal space, leaving the center of the hall free for customer movement. Such models often have one or two sides for displaying goods and can be assembled into a single line of any length.
Island display cases are used for placement in the center of the hall. They have access to the product from all four sides, which significantly increases the useful display area. Island models are often made lower so that the buyer can reach the product in the center. This is an excellent choice for promotional products or new products that need to be demonstrated as much as possible. island display cases. They have access to the product from all four sides, which significantly increases the useful display area. Island models are often made lower so that the buyer can reach the product in the center. This is an excellent choice for promotional products or new products that need to be demonstrated as much as possible.
There are also built-in options that are mounted into existing furniture or retail islands. They allow you to create a unified store interior design. However, when ordering such models, you need to know in advance the exact dimensions of the niche, since standards may differ from different manufacturers.
- 🏢 Wall-mounted - save space along the walls.
- 🏝️ Island - provide 360-degree access and high capacity.
- 🔧 Built-in —create a unique interior design.
- 📐 Corner —special modules for connecting lines at an angle of 90 or 135 degrees.
Specialized models for different products
Universal solutions do not exist, so the market offers highly specialized showcases. For example, confectionery models are distinguished by the presence of air humidifiers to prevent baked goods from getting too dry, and straight glass walls for a better view of the cakes. Meat display cases are often equipped with a ventilation system that prevents the cut of the product from weathering and preserves its presentation longer.
For drinks and dairy products they are used slides with inclined shelves. This design allows products to “slide” forward as they go down, making display easier and creating a feeling of abundance. Fish display cases may have a specially shaped ice bed or drainage systems for melt water, since fish is often stored directly on ice chips.
⚠️ Attention: Do not use a meat display to store fish or vice versa. Odors can be absorbed into seals and plastic, and different temperature requirements will lead to spoilage of products.
Separately available display displays for pizza (pizza cases), which maintain a temperature of about +10...+12°C. This is not quite a refrigerator in the classical sense, since the task here is not to freeze, but to maintain the freshness of the dough and filling, preventing them from drying out or souring.
Comparative table of characteristics
To systematize information about what a refrigerator display case is called and how they differ, we will provide a comparative analysis of the main parameters. This will help you quickly navigate the technical specifications for equipping a retail outlet.
td>Stable, but depends on the hall
| Parameter | Open showcase | Closed showcase | Horizontal chest |
|---|---|---|---|
| Access to goods | Free, without barriers | Through the door/glass | Top through the lid |
| Energy consumption | High (air curtain) | Medium/Low | Low |
| Temperature conditions | Very stable | Ideal for freezing | |
| Operating cost | High | Average | Low |
| Best application | Fast demand goods | Expensive/sensitive goods | Frozen semi-finished products |
As can be seen from the table, the choice between open and a closed system is always a compromise between customer convenience and resource savings business owner. For goods with high margins, closed systems are better suited, and for consumer goods with high turnover - open ones.
Selection criteria and technical nuances
When purchasing equipment, it is important to pay attention not only to the name, but also to the climate class. Climate class determines at what air temperature in the room the display case will work correctly. For Russia, classes SN (from +10 to +32°C) and N (from +16 to +32°C) are relevant. If the room is colder or hotter than the specified range, the compressor may not turn off or, conversely, not turn on, which will lead to damage to the equipment.
Another important parameter is the type refrigerant. Modern green refrigerants (such as R134a, R404A or new propane blends) are better for the environment, but may require more skilled maintenance. It is also worth checking the availability of certificates of conformity and a guarantee from the manufacturer.
☑️ Check before purchase
Do not forget about the overall dimensions and the ability to pass through doorways. It often happens that showcase it is ideally selected for functionality, but it is impossible to bring it into the store premises without dismantling the doors or windows. Measure all aisles in advance and compare them with the dimensions of the packaging.
⚠️ Attention: Manufacturers may change the technical characteristics and dimensions of models without prior notice. Always check the current data in the official catalog or specifications at the time of purchase.
Frequently asked questions (FAQ)
What is the difference between a display case and a refrigerated cabinet?
The main difference is in the design and access. Showcase designed to demonstrate goods to the buyer, it has a large glass area and often an open front part. A refrigerator is a closed container with blind or glazed doors, intended primarily for storing inventory, and not for direct sale with displays.
Is it possible to use a household freezer as a retail display?
It is strictly not recommended. Household appliances are not designed for constant door opening cycles, operation in a warm retail space and intense load. Compressor The household model will quickly fail, and the temperature regime will not meet sanitary standards for public places.
How often do you need to defrost the commercial appliance? showcase?
Most modern models are equipped with a system automatic defrostingthat is triggered by a timer or sensor. However, preventive complete defrosting and washing is recommended to be carried out at least once every 3-6 months, depending on the intensity of use and type of product.
Why does the display case not maintain the temperature?
There may be several reasons: freon leakage, thermostat malfunction, condenser contamination with dust or malfunction tightness of door seals. Also, the problem may be an overload of goods blocking the air ducts.
