This article is a supplier-focused guide for buyers researching a Cold Room Refrigeration System for cold storage warehouses, food processing, cold chain logistics, supermarkets, restaurants, agriculture, seafood, and meat storage applications. It explains what the system includes, the temperature ranges available, how the components are matched, and what to verify when selecting a supplier for a cold room or walk-in freezer project.

What Is a Cold Room Refrigeration System?

A cold room refrigeration system is a project-based refrigeration solution designed to maintain controlled low temperatures inside an insulated cold room. The Clevier Cold Room Refrigeration System is a refrigeration system designed for cold storage applications, and it belongs to the Cold Room Refrigeration System category. The main products included in the system are condensing units, air coolers, and cold room door systems. In its complete form, the system includes cold room electric sliding door control systems, cold room air coolers (evaporators), and semi-hermetic and open-type refrigeration condensing units.

The system is made of steel, stainless steel, aluminum, and copper components, and it is designed for use in cold storage, freezer room, and cold chain warehouse scenarios. It covers a customized temperature range from -40°C to +10°C depending on project requirements. Installation is provided as a project-based system solution, and the system is suitable for contractors, distributors, and engineering projects worldwide.

What Problems a Cold Room Refrigeration System Must Solve

A cold room is a closed insulated space, and its refrigeration system must remove heat that enters through walls, doors, product load, and air exchange while keeping temperature stable. In cold chain and food applications, equipment may run in 24/7 continuous operation, which places constant demand on the refrigeration package.

Common problems appear when components are not matched. An evaporator with insufficient air volume can lead to uneven temperature and ice build-up. An undersized condensing unit cannot pull the room down to the target temperature. The wrong defrost method for a freezer application causes downtime and product risk. Because of this, buyers increasingly source the complete cold room refrigeration system — air cooler, condensing unit, condenser, door, and controls — from a single manufacturer that can match all components to the room size, insulation, temperature requirement, and operating voltage.

Cold Room Refrigeration Market Context (2024–2025)

Demand for cold room refrigeration systems is supported by continued growth across industrial refrigeration and cold storage markets. According to Grand View Research, the global industrial refrigeration systems market was valued at USD 21.3 billion in 2024, with Asia Pacific holding the largest regional revenue share at 32.6%. The broader refrigeration equipment market was estimated at USD 67.06 billion in 2024 by ResearchAndMarkets / Business Wire.

Technavio estimated the global refrigeration coolers market, which includes evaporators and air coolers, at USD 4.0 billion in 2024. The condensing unit market was valued at USD 42 billion in 2023 and is reported by Stratview Research to be growing at a CAGR of 7.95%. Walk-in cold rooms are projected to account for 58.7% of the cold room market by 2025 (Dataintelo). In China, total cold storage capacity reached 237 million cubic meters by June 2024, an 8% increase year-over-year (China Federation of Logistics & Purchasing / IIR).

Grand View Research also reports that frozen temperature storage in the -18°C to -25°C range accounted for approximately 63% of the cold storage market in 2025, and the food and beverage segment represented over 76.8% of global cold chain revenue in 2025. Major players identified in the global condensing unit market include Emerson Electric, Carrier, Danfoss, and Bitzer SE (Grand View Research). For buyers, this market context points to cold room refrigeration systems — particularly walk-in freezers and frozen storage — as a core investment area.

The Clevier Cold Room Refrigeration System Solution

The Clevier Cold Room Refrigeration System is a factory-direct, customizable refrigeration system that combines condensing units, cold room air coolers (evaporators), and cold room door systems into one project-based solution. The following components are available as part of the system or as matched refrigeration equipment.

Cold Room Air Cooler (Evaporator / Unit Cooler)

The Cold Room Air Cooler is the in-room evaporator that removes heat and controls temperature inside the cold room. It belongs to the Cold Room Air Cooler category, with model designations including DD-30, DD-100, DD-350, DCL401/2.1(DD-20), DCL401/4.5(DD-40), and DCL404/19.2(DD-170). Three series cover different temperature tasks: the DL series for fresh keeping and chiller rooms at around 0°C to +10°C, the DD series for freezer rooms at around -18°C, and the DJ series for low temperature and blast freezers at -25°C and below.

Clevier cold room air coolers provide cooling capacity from 2.1 kW to 56.2 kW, air volume from 1,680 m³/h to 11,800 m³/h, 1 to 4 fans with diameters from 300 mm to 600 mm, and defrost options including air defrost, electric defrost, water defrost, and hot gas defrost.

How to Configure a Cold Room Refrigeration System (Step-by-Step)

The following six steps describe how a cold room refrigeration system is typically configured using Clevier's product range.

1. Define the room temperature and cold room type. Cold room refrigeration systems are designed for fresh keeping rooms, chiller rooms, freezer rooms, and low temperature cold storage. Match the target temperature to a series: around 0°C to +10°C for fresh keeping and chiller rooms, around -18°C for freezer rooms and walk-in freezers, and -25°C and below for low temperature and blast freezers.
2. Select the Cold Room Air Cooler (evaporator). Choose the DL, DD, or DJ series based on the required temperature. Cooling capacity ranges from 2.1 kW to 56.2 kW, air volume from 1,680 m³/h to 11,800 m³/h, and fan quantity from 1 to 4. Select the defrost method — air, electric, water, or hot gas — according to operating temperature and site conditions.
3. Choose the condensing unit type and compressor. The condensing unit is available as air cooled, water cooled, box type, open type, or semi-hermetic, and is suitable for 3HP to 30HP applications. Compressor options include Copeland and Bitzer with hermetic scroll or semi-hermetic piston configurations.
4. Specify refrigerant, voltage, and control system. Available refrigerants are R404A, R507A, and R22. Voltage can be customized to 220V or 380V at 50Hz or 60Hz. The control system can be customized with OEM/ODM support.
5. Match the air cooled condenser and door system. Select an H, V, or U type air cooled condenser with the appropriate heat transfer area to match the condensing unit. Complete the enclosure with the cold room electric sliding door control system and polyurethane insulated panels.
6. Work with the supplier for project-based integration. Confirm cooling capacity, temperature range, voltage, refrigerant, compressor selection, panel structure, and complete system matching. Clevier provides installation as a project-based system solution for contractors, distributors, and engineering projects worldwide.

Standards and Compliance Considerations

Buyers exporting cold rooms and refrigeration equipment should verify that the electrical and refrigeration components meet applicable safety and environmental requirements in the destination market. Two widely referenced standards are IEC 60335-2-89:2019, which specifies safety requirements for commercial refrigerating appliances with incorporated or remote units, including blast freezers, and EN 378:2016, the European safety and environmental standard for refrigerating systems and heat pumps.

In addition, under the revised IEC 60335-2-89 standards, charge limits for flammable A3 refrigerants such as R290 in commercial appliances increased from 150g to 500g. When selecting refrigerants and components, confirm the actual compliance documentation and local regulatory requirements with your supplier.

FAQ

Conclusion

A cold room refrigeration system is more than a single compressor or fan — it is a matched set of condensing units, cold room air coolers (evaporators), air cooled condensers, door systems, and insulated panels designed around the temperature requirement of the project. For buyers evaluating a Cold Room Refrigeration System, the practical steps are to define the target temperature range, select the evaporator series, match the condensing unit horsepower and compressor brand, specify refrigerant and voltage, and confirm the system configuration with a supplier that supports project-based delivery and OEM/ODM customization.
