Mini Cold Storage (Walk-in Cold Room) scale from 5m³ to 50m³ (capacity 1 ton – 10 tons) This is the optimal preservation solution for restaurants, clean food chains, school canteens, agricultural cooperatives, seafood purchasing facilities, and pharmaceutical laboratories. Instead of using multiple energy-consuming and frequently malfunctioning household freezers, a modular, integrated cold storage system expands storage space up to five times and provides precise temperature control. +2°C to +8°C (cool storage) or -18°C to -22°C (freezer) and save more than 35% in electricity costs each month.
🏢 Tan Long General Contractor's Module Standardization Capabilities
Inheriting technology from large-scale cold storage projects with tens of thousands of pallets (NECS 102,642 pallets, AJ Total, Meito Vietnam, Saigon Food), Tan Long has standardized its line of modular industrial mini cold storage units:
- Camlock-mount PIR panel enclosure: Quick assembly within 24-48 hours, and can be easily disassembled and relocated when moving business premises.
- Imported complete compressor unit: Using Copeland (USA), Bitzer (Germany), or Danfoss compressors with integrated inverter technology, the noise level is low, below 50 dB.
- 24-month manufacturer's warranty: Our team of engineers provides 24/7 technical support nationwide.

2. Should You Buy a Used Mini Cold Storage Unit at a Cheap Price?
Many business owners, in an attempt to save on initial costs, have opted to purchase used mini cold storage systems that are being liquidated on the market. However, based on Tan Long's practical maintenance experience, the risks that arise after 3-6 months of use are often very costly:
- Old PU/EPS panels are aging and absorbing moisture: The insulation foam absorbs moisture, losing its heat retention capacity, causing condensation and ice formation on the casing, forcing the compressor to run continuously 24/7 without interruption, doubling the monthly electricity bill.
- The old compressor has lost pressure (worn pistons/bearings): Frequent incidents include coil failure, overheating causing relay tripping, or refrigerant leaks, leading to a sudden surge in warehouse temperature and potentially damaging entire batches of food or pharmaceuticals inside.
- The cost of repairs exceeds the cost of buying a new one: Investing in a new, technically sound modular system provides businesses with complete peace of mind, sustainable depreciation over 10-15 years, and savings of millions of dong in electricity costs every month.
3. Superior Design Features of Tan Long Mini Cold Storage
- Camlock flush-mounted door lock: The panels are joined together perfectly using a pre-molded Camlock hexagonal locking system embedded within the insulation foam, without exposed screws, preventing heat loss and making disassembly extremely convenient when relocating the warehouse.
- T-Light cold storage doors with anti-jamming feature: High-elasticity rubber seals on all four sides, automatic lifting hinges when opened, and a safety lock with an internal emergency exit latch (preventing the risk of people getting trapped in a cold room).
- Smart microcontroller control panel: Integrated phase loss, phase reversal, and overcurrent protection relays; Dixell/Elitech temperature display with extremely low temperature setting error of only ±0.5°C.
4. Cost Estimate Table for the Construction of a B2B Mini Cold Storage Warehouse
| Component Items | Technical Standards Meet the Standards | Estimated Proportion |
|---|---|---|
| Condensing unit compressor | Copeland / Danfoss / Bitzer complete unit, quiet airflow cooling fan. | 40% – 45% |
| Insulated casings & Special doors | PIR panel 75-100mm, Colorbond antibacterial steel, Camlock lock. | 30% – 35% |
| Ceiling-mounted air conditioner | Industrial evaporator with large fins, automatic defrosting using electric resistance. | 15% – 18% |
| Electrical cabinets & accessories | Dixell controller, deep-soundproof LED lights, Cadivi insulated wiring. | 8% – 10% |
