Cold Room Refrigeration System: Components and Supplier Guide

A cold room refrigeration system is a coordinated set of refrigeration components that maintains a controlled temperature in cold storage spaces. It typically includes a condensing unit, a cold room air cooler (also called a cold room evaporator or unit cooler), and a cold room door system. This guide explains how these components work together and what buyers should evaluate when looking for cold room refrigeration system suppliers.

Defining the Problem: Matching Components to the Cold Room

A cold storage project depends on components being matched to the room’s operating temperature and application. The condensing unit rejects heat, the cold room air cooler removes heat from the room, and the door system controls how much warm air enters. If these parts are not matched, the room may not reach temperature, energy use can rise, and the compressor may cycle too often. This is why procurement questions about cold room refrigeration system suppliers usually begin with product composition rather than brand alone.

Industry Context: Cold Storage Demand and Refrigeration Equipment

Cold storage demand is increasing across food processing, cold chain logistics, and supermarket distribution. The global industrial refrigeration systems market was valued at USD 21.3 billion in 2024 (Grand View Research). The global refrigeration equipment market was estimated at USD 67.06 billion for 2024 (ResearchAndMarkets via Business Wire). The condensing unit market was valued at USD 42 billion in 2023 and is growing at a reported CAGR of 7.95% (Stratview Research). The global refrigeration coolers market, covering evaporators and air coolers, was estimated at USD 4.0 billion in 2024 (Technavio).

Regional and segment data also show where demand is concentrated. Asia Pacific accounted for 32.6% of the industrial refrigeration systems market in 2024 and led the condensing unit market with a 70.22% revenue share in 2023 (Grand View Research). China’s total cold storage capacity reached 237 million cubic meters by June 2024, an 8% increase year over year (China Federation of Logistics & Purchasing / IIR). Walk-in cold rooms are projected to hold a 58.7% market share within the cold room market by 2025 (Dataintelo). The frozen temperature range of -18°C to -25°C held the largest share of the cold storage market, approximately 63%, in 2025 (Grand View Research). Food and beverages accounted for over 76.8% of global cold chain market revenue in 2025 (Grand View Research).

The Cold Room Refrigeration System from Clevier

Clevier Refrigeration (Jiangsu) Co., Ltd. is a manufacturer specializing in commercial and industrial refrigeration equipment and cold storage solutions. Based in Wujin District, Changzhou City, Jiangsu Province, China, Clevier supplies cold room refrigeration systems, condensing units, refrigeration units, cold room air coolers, evaporators, air cooled condensers, polyurethane insulated panels, and cold room related equipment.

Clevier’s Cold Room Refrigeration System is a product category that includes condensing units, air coolers, and cold room door systems. It is designed for cold storage, freezer room, and cold chain warehouse scenarios. The system is made of steel, stainless steel, aluminum, and copper components. Depending on project requirements, the system can be configured for temperatures from -40°C to +10°C, with 220V or 380V power supply options and OEM/ODM customization.

The company also provides complete refrigeration solutions for food processing, cold chain logistics, supermarkets, restaurants, agriculture, seafood, meat storage, and other industries.

Step-by-Step Selection Process

The selection process can be organized into six steps. Each step corresponds to a component that Clevier manufactures or matches in its system offering.

Step 1. Define the temperature range and room type

Clevier’s cold room air coolers are available in three series: DL, DD, and DJ. The DL series is designed for fresh keeping and chiller rooms around 0°C to +10°C. The DD series is designed for freezer rooms around -18°C. The DJ series is designed for low temperature and blast freezer applications at -25°C and below.

Step 2. Select the condensing unit

The refrigeration condensing unit category includes air cooled, water cooled, box type, and open type configurations. Model designations include Air Cooled Condensing Unit, Semi-hermetic Condensing Unit, Box Type Condensing Unit, and Water Cooled Condensing Unit. The unit is suitable for 3HP to 30HP refrigeration applications. Compressor options include Copeland and Bitzer, with hermetic scroll or semi-hermetic piston configurations. Refrigerants can be R404A, R507A, or R22, and voltage can be customized to 220V, 380V, 50Hz, or 60Hz.

Step 3. Match the cold room air cooler / evaporator

Model designations include DD-30, DD-100, DD-350, DCL401/2.1(DD-20), DCL401/4.5(DD-40), and DCL404/19.2(DD-170). Fan diameter ranges from 300mm to 600mm, fan quantity from 1 to 4, air volume from 1,680m³/h to 11,800m³/h, and cooling capacity from 2.1kW to 56.2kW. Defrost can be provided by air defrost, electric defrost, water defrost, or hot gas defrost according to different temperature requirements. The housing can be made of galvanized steel, stainless steel, or aluminum plate.

Step 4. Configure the condenser

For the condenser side, Clevier’s air cooled condenser series are H Type, V Type, and U Type. They are built with copper tube, aluminum fin coil, and steel housing. Heat transfer area is approximately 22-400m² depending on model. Fan configuration is 1-4 fans with 300mm-600mm diameter, and voltage can be customized.

Step 5. Integrate the door system and controls

The cold room refrigeration system also includes cold room electric sliding door control systems, cold room air coolers (evaporators), and semi-hermetic and open-type refrigeration condensing units. Installation is provided as a project-based system solution, meaning the components are matched and delivered as a package for contractors and engineering projects.

Step 6. Use OEM/ODM options for project-specific matching

Clevier supports OEM/ODM customization including cooling capacity, temperature range, voltage, refrigerant, compressor selection, panel structure, and complete system matching. This is relevant for distributors and contractors who need a branded or project-specific configuration.

Use Cases

Clevier’s cold room refrigeration equipment is intended for the cold storage warehouse industry, food processing industry, and seafood and meat processing industries. Typical application scenarios include cold storage warehouses, food processing plants, meat storage, seafood storage, fruit and vegetable storage, supermarkets, restaurants, and cold chain logistics. The system is designed for fresh keeping rooms, chiller rooms, freezer rooms, and low temperature cold storage, including blast freezing applications.

The system is suitable for contractors, distributors, and engineering projects worldwide.
