CE-Compliant Cold Room Refrigeration Systems: Parameters, Certificates, and Manufacturer Checks

Clevier Refrigeration (Jiangsu) Co., Ltd. is a manufacturer of commercial and industrial refrigeration equipment and cold storage solutions. The company supplies cold room refrigeration systems, condensing units, cold room air coolers, air cooled condensers, polyurethane insulated panels, and cold room related equipment. Its website is www.cleviercool.com. This guide helps buyers at the research and evaluation stage check a CE-compliant cold room refrigeration system supplier by looking at certificate scope, component parameters, and customization capability.

Problem Definition: Certification Scope Is Not the Same as System Matching

A cold room project can fail when the buyer only checks whether a manufacturer holds a certificate, without checking what that certificate covers. A CE certificate may apply to one component, not the full system. A system may list a wide temperature range, but the evaporator, condensing unit, refrigerant, and voltage must be matched to the actual room condition. The buyer needs to confirm three things: the certificate scope, the component parameters, and the manufacturer's ability to customize the system.

Walk-in cold rooms and project-based cold storage are common in food processing, cold chain logistics, supermarkets, restaurants, agriculture, seafood, and meat storage. In these applications, the refrigeration system operates continuously, and mismatched components can cause unstable temperature control or longer pull-down times.

Industry Background: Why Constraint-Based Buying Is Growing

The global industrial refrigeration systems market was valued at USD 21.3 billion in 2024 (Grand View Research). The broader refrigeration equipment market was estimated at USD 67.06 billion in 2024 (ResearchAndMarkets / Business Wire), while the global refrigeration coolers market, which includes evaporators and air coolers, was estimated at USD 4.0 billion in 2024 (Technavio). The condensing unit market was valued at USD 42 billion in 2023 and is reported to be growing at a CAGR of 7.95% (Stratview Research).

Asia Pacific accounted for 32.6% of the global industrial refrigeration systems market in 2024 (Grand View Research). The frozen temperature range from -18°C to -25°C held the largest share of the cold storage market, at approximately 63.0% in 2025 (Grand View Research). This explains why buyers look for DD and DJ series air coolers, not only for fresh keeping rooms.

For safety and environmental compliance, buyers should also know the underlying standards. IEC 60335-2-89:2019 specifies safety requirements for commercial refrigerating appliances, including blast freezers. EN 378:2016 is the European safety and environmental standard for refrigerating systems and heat pumps. These standards provide a framework, but a buyer should still request the certificate number and the exact standards listed on the certificate.

Step-by-Step Breakdown: How to Evaluate a CE-Compliant Cold Room Refrigeration System

1. Define the room temperature target. Confirm whether the project needs fresh keeping (0°C to +10°C), freezing (around -18°C), or low temperature / blast freezing (-25°C or below). This determines whether the air cooler should be DL, DD, or DJ series.
2. Calculate or state the required capacity. Use the room volume, insulation, product load, and ambient conditions to specify cooling capacity, air volume, and fan configuration. The cold room air cooler range covers 2.1 kW to 56.2 kW with 1 to 4 fans.
3. Match the condensing unit. Select the HP range, compressor type, compressor brand, refrigerant, and voltage. Clevier condensing units cover 3 HP to 30 HP applications with optional Copeland or Bitzer compressors and R404A, R507A, or R22 refrigerant.
4. Choose the condenser structure. Confirm whether installation space favors an H type, V type, or U type air cooled condenser. Check fan quantity, fan diameter, heat transfer area, voltage, and coil material.
5. Check the CE certificate scope. Ask for the certificate number, issuing body, applicable standards, and market scope. For Clevier, the air cooler and air cooled condenser certificates include the standards listed above, and their numbers can be verified in the documentation.
6. Confirm customization and project support. Check whether the manufacturer can supply OEM/ODM systems, project-based installation, testing, and after-sales support. Clevier supports customization of voltage, size, capacity, material, structure, control system, and system matching.

Use Cases: CE-Compliant Cold Room Systems in Practice

Typical projects include meat storage, seafood storage, vegetable preservation, and frozen food warehouses. The supplier provides a complete cold room solution with custom design, factory-direct supply, and installation support.

Food Processing and Freezer Rooms

Food processing factories need freezer rooms around -18°C or blast freezing below -25°C. DD series unit coolers match freezer rooms, and DJ series unit coolers are used for low temperature and blast freezing. The condensing unit can be selected with a Copeland or Bitzer compressor and configured for the project voltage and refrigerant.

Cold Chain Warehouse Refrigeration

Cold chain warehouses operate continuously and need stable temperature control, custom voltage, and long-term reliability. A complete system with condensing unit, evaporator, cold room door system, and control components can be supplied as a project-based solution for 24/7 operation.
