What to Verify in a Cold Storage Project: Certifications, Specifications, and EPC Scope

Short answer: Before approving a cold storage investment, buyers should verify the project certification basis, temperature range, panel specification, refrigeration equipment parameters, and the exact scope of installation and commissioning services. A certified EPC contract can simplify this process because design, equipment supply, installation, and after-sales maintenance are handled by one responsible party.

Problem Definition: Why Cold Storage Projects Miss Specification and Compliance Requirements

Buyers evaluating cold storage installation often compare square meters, tonnage, and price before checking whether the proposed design can actually hold the required temperature. In practice, a cold storage project is a combination of insulation boards, refrigeration compressor equipment, evaporators, condensing units, structural drawings, electrical supply, and on-site installation labor. If these elements are not specified together, the project may face temperature instability, higher operating costs, and delayed commissioning.

Another common issue is incomplete certification evidence. A supplier can say that its cold storage equipment is certified, but a serious buyer should ask which standard applies, which body issued the certificate, and which product scope the certificate covers. For a food-related facility, this is not paperwork. It affects food safety, project acceptance, and the ability to sell or rent the facility later.

When comparing cold storage design companies and cold storage installation companies, the practical question is not only how a cold storage is priced but also what is delivered: cold storage design drawings, refrigeration equipment, insulation panels, installation guidance, commissioning, spare parts, and after-sales service.

Industry Background: Cold Storage Demand and Compliance Pressure

Cold storage demand continues to expand globally. According to Grand View Research, the global cold storage market was valued at approximately USD 185.8 billion in 2025 and is projected to reach USD 474.2 billion by 2033. Market Research Future values the cold storage construction market at USD 78.96 billion in 2024, with an expected CAGR of 7.14% through 2035. Strategic Market Research estimates the refrigeration compressor market at USD 18.6 billion in 2024, driven by rising cold chain logistics demand and energy-efficient HVAC systems.

Temperature strategy is one of the most important decisions in this market. Grand View Research reports that the frozen temperature range segment, defined as -18°C to -25°C, held the largest market share at 63.0% in 2025. This explains why many buyers request frozen storage even if their current product mix is fresh fruit and vegetables. Buyers should design for the products they store today, while leaving realistic expansion potential for frozen and quick-freezing zones.

Compliance expectations are also becoming clearer. EN 378 is the primary European safety and environmental standard for the design, construction, and installation of refrigerating systems and heat pumps, according to the European Committee for Standardization (CEN). Export-oriented buyers should review both the supplier quality certificate and the relevant regional standards for the final destination.

A documented quality system and correct regional standards together reduce the risk of rejection during installation or customs clearance.

Step-by-Step Breakdown: What to Check Before Installing a Cold Storage Facility

Step 1: Define the product type, temperature band, and project scale

Cold storage design starts with the product to be stored. Fresh fruit and vegetable cold storage often uses 0 to 5°C. Frozen food commonly uses -18 to -25°C. Quick freezing can require -35 to -45°C. In HOWCOOL projects, area, height, tonnage, and temperature can all be customized, with cold storage projects ranging from a minimum of 500 tons to 20,000 tons.

Step 2: Confirm the insulation board specification

Insulation boards directly affect temperature stability. HOWCOOL configurations use polyurethane insulation board in selected models, with 150 mm thickness and 42 kg density in the HSZL-3000T. The HSZL-5000t uses PIR board at 100 mm or 150 mm. A buyer should ask for the insulation type, thickness, and density rather than accepting a generic description of a cold storage insulation board.

Step 3: Lock the refrigeration compressor equipment and refrigerant

The refrigeration compressor unit is the core equipment in the system. For export projects, voltage and frequency must match the destination. HOWCOOL systems are documented at 380-415V/3P/50Hz. Refrigerants include R507, R404A, and environmentally friendly Freon. Confirm the refrigerant type because local environmental regulations may restrict certain gases.

Step 4: Verify certification and quality-control evidence

Ask for the certification standard, certifying body, certificate number, and product scope. HOWCOOL uses ISO 9001:2015 with certificate number 06526Q01032R001, issued by Beijing China IoT Joint Certification Center. For international procurement, HOWCOOL also supports pre-shipment tests and third-party inspection, including SGS inspection.

Step 5: Review the complete EPC scope, drawings, and installation responsibilities

An EPC scope should include design, equipment supply, installation, commissioning, and after-sales maintenance. For HOWCOOL projects, the company provides steel structure drawings and refrigeration equipment, and on-site technical engineers install and debug the system. Buyers should request clear drawings before signing, including steel structure drawings, refrigeration drawings, and any air-conditioning/cold storage drawings in the EPC package. The expected construction period for projects from 1,000 to 15,000 square meters is 2 to 5 months.

Step 6: Confirm lead time, MOQ, and after-sales service

For OEM cold storage projects, HOWCOOL offers a lead time of 30 to 45 days, a monthly capacity of 100 units, and a minimum order quantity of 500 tons. The HSZL-3000T configuration includes spare parts for two years. HOWCOOL also provides lifetime technical service as part of its after-sales commitment.
