Structural Design & Core Features
Modular High-Density PU Insulation Structure
The main structure features premium plug-in Polyurethane (PU) insulation panels utilizing an eccentric cam-lock system for rapid assembly and airtight sealing. Packed with high-density PU foam and reinforced with anti-corrosion double-sided panels, the thermal conductivity is exceptionally low. This structural design reduces cooling loss and lowers energy consumption by over 15% compared to traditional onsite builds, boasting a service life of over 10 years.
Flexible High-Mobility Engineering
Engineered with heavy-duty caster wheels and a robust industrial brake mechanism, this cold storage unit can be rolled across flat surfaces smoothly without digging trenches or pouring concrete foundations. When operational requirements change or space becomes limited, the entire cold room can be rapidly redeployed, making it an asset for multi-scenario use and temporary site management.
Heavy-Duty Anti-Slip Cement Fiber Floor
The interior flooring is built with a heavy-duty 18mm cement fiber board that safely handles high load capacities, foot traffic, and material carts. It provides a non-slip, wear-resistant surface that stands up to humid, high-moisture environments while remaining incredibly easy to clean and sanitize.
Heavy-Duty Cold Room Door with Safety Escape Lock
The custom-thickened insulated cold storage door is equipped with low-temperature resistant EPDM rubber gaskets for a reliable thermal break. For maximum operational safety, it integrates an internal safety escape release mechanism, allowing anyone inside to open the door easily in emergencies. The exterior features a rugged mechanical key-lock system to secure high-value inventory.

Advanced Refrigeration & Intelligent Control
  • Plug-and-Play Monoblock Refrigeration Unit: Featuring a highly integrated, pre-charged drop-in refrigeration system, it eliminates complex onsite piping and professional copper-welding. Factory tested and calibrated, it runs straight out of the box. Powered by top-tier brand compressors, the unit offers fast pull-down times, low vibration, and quiet operation.
  • Microcomputer Smart Thermostat: Take complete control with an intuitive digital interface that manages automated temperature control, scheduled smart defrost cycles, and instant system fault or over-temperature alerts—minimizing manual supervision.
  • Energy-Saving Air Curtain System: Positioned directly above the cold room door, the automatic air curtain creates a powerful, invisible air barrier whenever the door opens. This dramatically cuts down cold-hot air exchange, prevents inner condensation and frost buildup, and stabilizes the interior climate.

Core Product Advantages
  • Zero Civil Infrastructure Required: Deploy immediate commercial refrigeration without civil construction permits, brick-and-mortar builds, or dedicated equipment rooms.
  • Exceptional Energy Efficiency & Low Opex: The combination of precision cam-lock PU panels, an integrated air curtain, and a high-EER monoblock unit ensures ultra-low daily operating costs.
  • Precise Climate Control for Ingress Security: Constant uniform airflow leaves zero thermal dead zones, protecting the quality of your perishables. Added security locks and safety releases give you total peace of mind.
  • Durable & Low-Maintenance Asset: Standardized components, reliable brand compressors, and anti-corrosive materials reduce downtime and ensure long maintenance intervals.
  • High Adaptability Across Markets: The adjustable temperature profile allows you to seamlessly switch between fresh produce preservation, meat freezing, and medical cold chain storage.
