When choosing commercial refrigeration equipment for a supermarket, grocery store, convenience store, or other food retail business, you may come across two common options: plug-in and remote refrigerated cabinets.
But what exactly is a plug-in refrigerated display cabinet, and how does it work?
A plug-in refrigerated display cabinet has its own integrated refrigeration system. Unlike remote refrigeration equipment, it does not normally require connection to a separate external refrigeration system.
This makes plug-in refrigeration a practical option for many retail applications, particularly when businesses need self-contained refrigeration equipment that can be installed and operated independently.
In this guide, we explain what plug-in refrigeration is, how it works, its main benefits, the different types available, and what you should consider before choosing a plug-in refrigerated cabinet.

What Is a Plug-In Refrigerated Display Cabinet?
A plug-in refrigerated display cabinet is a commercial refrigeration unit with its own built-in cooling system.
The refrigeration components are integrated into the cabinet, allowing the equipment to provide cooling without being connected to a separate central refrigeration system.
Plug-in refrigerated cabinets can be used in a variety of commercial environments, including:
- Supermarkets
- Grocery stores
- Convenience stores
- Food markets
- Retail stores
- Small and medium-sized commercial food businesses
The exact cabinet type depends on the products being displayed, available space, required temperature, and store layout.
How Does a Plug-In Refrigerator Work?
The basic principle of a plug-in refrigerated cabinet is relatively straightforward.
The cabinet contains its own refrigeration components, which remove heat from the refrigerated space and maintain the required temperature.
The general process includes:
- The refrigeration system removes heat from inside the cabinet.
- The refrigerant circulates through the refrigeration circuit.
- The evaporator absorbs heat from the refrigerated area.
- The condenser releases the removed heat.
- The cabinet maintains the appropriate temperature for the products being stored or displayed.
Because the refrigeration system is integrated into the cabinet, the unit can operate independently without requiring connection to a separate central refrigeration system.
Plug-In vs. Remote Refrigeration
The biggest difference between plug-in and remote refrigeration is the location of the refrigeration system.
Plug-In Refrigeration
With a plug-in cabinet:
- The refrigeration system is integrated into the cabinet.
- The cabinet operates as a self-contained unit.
- It does not normally require connection to an external refrigeration system.
- Installation can be simpler for suitable applications.
- Individual cabinets can operate independently.
Remote Refrigeration
With a remote cabinet:
- The refrigeration system is located separately from the cabinet.
- The cabinet connects to an external refrigeration system.
- Multiple cabinets can be integrated into a larger refrigeration infrastructure.
- It can be particularly suitable for larger supermarket and hypermarket projects.

Neither system is automatically better than the other.
The right choice depends on your store size, number of cabinets, available infrastructure, installation requirements, product range, and long-term refrigeration plans.
What Are the Advantages of Plug-In Refrigerated Cabinets?
Plug-in refrigeration offers several practical benefits for businesses that need self-contained commercial refrigeration equipment.
1. Self-Contained Refrigeration
One of the biggest advantages is that the refrigeration system is integrated into the cabinet.
This means the cabinet does not normally need to be connected to a separate central refrigeration system.
For businesses that require individual refrigeration units, this can make the planning process more straightforward.
2. Simpler Installation for Suitable Applications
Because the cooling system is built into the cabinet, plug-in equipment can have fewer external refrigeration infrastructure requirements than a remote system.
The exact installation requirements still depend on the equipment and project, but the self-contained design can be convenient for many retail applications.
3. Flexible Placement
Plug-in cabinets can provide flexibility when arranging refrigeration equipment within a store.
Businesses can select individual units according to their product categories and available space.
This can be particularly useful when refrigeration requirements are limited to specific areas of the store.
4. Independent Operation
Each plug-in cabinet has its own refrigeration system.
This means different cabinets can operate independently according to their individual requirements.
For smaller stores or businesses that do not need a centralized refrigeration system, this can be a practical approach.
5. Suitable for Different Retail Applications
Plug-in refrigeration is available in several cabinet configurations, allowing businesses to select equipment according to their products and store layout.
Common options include multidecks, counters, freezers, and S.V. multidecks.
What Types of Plug-In Refrigerated Cabinets Are Available?
Plug-in refrigeration is not limited to one cabinet design.
The right equipment depends on what you are selling and how you want to display it.
Plug-In Refrigerated Multidecks
Plug-in multidecks provide vertical refrigerated display space and can be suitable for supermarkets, grocery stores, and other retail environments.
They can be used for products such as:
- Dairy products
- Chilled beverages
- Packaged foods
- Fresh products
- Ready-to-eat foods
Their vertical layout allows businesses to display multiple product levels while making products easy for customers to see and access.
For businesses looking for this type of equipment, plug-in refrigerated multidecks are an important option to consider.
Plug-In Refrigerated Counters
Refrigerated counters can combine refrigerated storage with a practical counter-style configuration.
They can be useful in food retail environments where staff require convenient access to refrigerated products or where a counter configuration works better with the store layout.
Plug-in refrigerated counters can be considered when a self-contained refrigeration solution is preferred.
Plug-In Refrigerated Freezers
If your business sells frozen foods, you will need refrigeration equipment specifically designed for frozen products.
Plug-in freezers have an integrated refrigeration system and can provide a practical solution for businesses that need individual freezer units.
They can be used for products such as:
- Frozen vegetables
- Frozen meals
- Ice cream
- Frozen meat

The equipment should always be selected according to the required temperature range and product specifications.
Plug-In S.V. Multidecks
S.V. multidecks provide another configuration for commercial refrigeration applications.
They can be considered when the store layout, product range, and display requirements call for a specific multideck design.
The best configuration depends on the individual project and the products that need to be displayed.
When Should You Choose a Plug-In Refrigerated Cabinet?
Plug-in refrigeration can be a suitable option when you need self-contained refrigeration equipment without connecting each cabinet to a central refrigeration system.
It may be worth considering when:
- You are opening a small or medium-sized store.
- You need individual refrigerated cabinets.
- A central refrigeration system is not available.
- You want flexibility in cabinet placement.
- You need refrigeration for specific areas of a store.
- You want different cabinet types for different products.
- You are adding refrigeration equipment to an existing store.
For larger supermarkets with many refrigeration cabinets, however, a remote system may also be worth considering.
The decision should be based on the complete refrigeration project rather than cabinet type alone.
Is Plug-In Refrigeration Suitable for Supermarkets?
Yes, plug-in refrigeration can be used in supermarkets, but suitability depends on the size and requirements of the project.
A supermarket with a limited number of refrigerated cabinets may find plug-in equipment convenient because each cabinet has its own cooling system.
Larger supermarkets with many refrigerated cabinets may instead consider remote refrigeration as part of a centralized system.
Before making a decision, consider:
- Number of refrigerated cabinets
- Store size
- Available technical space
- Product categories
- Required temperature ranges
- Energy consumption
