Modular Pre-Fab Cam-Lock Cold Room Panels
Modular cold storage systems (also called prefabricated or modular cold storage systems) are a key solution for modern cold chain storage. Unlike traditional brick-and-mortar cold storage, which takes a long time to build and can't be moved, these systems

Main features
Five Core Components of a Complete System
A complete prefabricated cold storage system mainly consists of the following major modules, which are prefabricated and integrated in the factory:
1. Storage Enclosure System (Insulated Panels)
• Wall Panels: Usually made of polyurethane (PU) double-sided color steel sandwich panels (high-end options include stainless steel or embossed aluminum panels). They achieve seamless assembly through tongue-and-groove design with built-in eccentric hooks (protrusion limits).
• Doors: Equipped with electric roll-up doors, sliding doors, or manual doors with anti-freeze heating wires. The edges have high-elasticity seals to prevent cold air leakage.
2. Refrigeration Power System (Cooling Core)
• Outdoor Units: Include compressors (fully enclosed scroll, semi-hermetic piston, or screw types), condensers, and receivers. Major brands like Gree and Sanhua promote integrated modular refrigeration units, pre-assembled with valves and pre-charged with refrigerant, so no on-site welding is needed.
• Indoor Evaporators: Ceiling-mounted air-cooled units are commonly used to quickly circulate and cool the air inside the storage.
3. Electrical and Smart Control System
• Equipped with a microcomputer automatic control cabinet (PLC), with standard IoT GPRS/Wi-Fi modules.
• Functions include automatic temperature control, automatic temperature and humidity recording, automatic defrosting (electric or water), and remote fault alerts.
4. Piping and Expansion System
• Includes precision control components like thermostatic expansion valves (or electronic expansion valves), solenoid valves, driers, sight glasses, and shock-absorbing pipes.
5. Auxiliary Facilities and Safety Systems
• Air curtains (to reduce cold loss when doors open), moisture-proof/explosion-proof LED lights designed for cold storage, internal emergency exit door locks, and pressure-equalizing windows.
| Modular Assembly | All warehouse panels follow building modules and can be assembled on site with hooks, no civil construction needed | Super short construction time (usually a small warehouse can be delivered in 3-5 days) |
| Detachable and Relocatable | The warehouse can be disassembled anytime, moved to a new site and reassembled, or expanded on the original site | High asset retention, suitable for rented sites or business adjustments |
| High Space Utilization | Inside the warehouse, you can partition as needed, even design it as a combined dual-temperature warehouse (like refrigerated + frozen) | Flexibly meets different temperature storage needs for various goods |
| Efficient Insulation and Energy Saving | Polyurethane foam core has a very low thermal conductivity and great seal at joints | Low running costs, minimal temperature fluctuations, high food preservation quality |
• Temperature requirements: Cold storage (0~5℃ for fruits and vegetables), freezer (-18~-23℃ for meat and frozen goods), or quick-freeze storage (below -35℃).
• Size and layout: The length, width, and height of the site. Check if partitions are needed for dual-temperature storage.
• Cooling source selection: For small storage, it’s best to go with an easy-to-use all-in-one unit or a standardized split unit; for medium to large storage, choose parallel units or screw compressors based on energy-saving needs.
