Each solution is designed with durability, precision control, and long-term operational efficiency in mind.

🌿 1. Preservation Cold Room: Keeping Freshness at Its Peak

Focusun’s Preservation Cold Rooms are ideal for the storage of fruits, vegetables, dairy, and beverages that require a stable temperature between 0°C and 15°C. These units prioritize humidity control, airflow design, and uniform temperature distribution, ensuring that produce retains its natural texture, color, and shelf life.

Whether it’s a supermarket, hotel kitchen, or farm distribution center, our fresh-keeping rooms are built using modular PU panels, efficient refrigeration units, and smart PLC/HMI interfaces, allowing users to manage their storage conditions with ease.

Applications: Fresh food logistics, supermarkets, florists, restaurants, agricultural co-ops
Optional Features: Antibacterial coatings, remote temperature monitoring, dual-zone controls

❄️ 2. Refrigerated Cold Storage: Reliable Cold Chain for Perishable Goods

Designed to maintain temperatures from -5°C to -18°C, our Refrigerated Cold Storage Rooms are the backbone of most cold chain systems. These rooms are widely used to store meat, seafood, dairy, frozen packaged food, and pharmaceuticals.

Focusun provides both static and dynamic cold storage options, with features such as energy-saving condensing units, low-temperature insulation panels, and multi-point temperature sensors. The systems are compatible with racking solutions and forklift operations for industrial-scale logistics.

Applications: Distribution centers, food factories, cold chain logistics hubs, pharmaceutical warehouses
Core Advantages: Energy-efficient scroll or screw compressors, CO₂/NH₃/R404A systems, automated defrost, HACCP compliance

⚡ 3. Blast Freezer Room: Rapid Freezing, Maximum Protection

For food processing facilities, fisheries, and frozen food manufacturers, freezing speed is critical. Focusun’s Blast Freezer Rooms are engineered for ultra-low temperature environments (down to -45°C) that enable fast freezing within hours, locking in product freshness, texture, and nutrition.

We utilize high-capacity condensing units, powerful axial fans, and rapid heat-exchange evaporators to ensure that products are frozen evenly and quickly. Our blast freezers meet international food safety standards and are adaptable to various volumes and production schedules.

Applications: Slaughterhouses, seafood processors, frozen food factories
System Highlights: Dual-compressor configurations, time-programmed freeze cycles, smart alarms, rapid temperature pull-down

☀️ 4. Solar-Powered Cold Rooms: Off-Grid Cooling for Remote Locations

Addressing cold chain challenges in remote, power-deficient, or off-grid regions, Focusun has developed Solar-Powered Cold Rooms — an eco-friendly and autonomous solution powered by photovoltaic panels + battery storage + DC refrigeration technology.

This system is ideal for rural agricultural centers, vaccine preservation programs, and humanitarian food supply chains. It offers up to 24 hours of autonomy without sunlight and requires minimal maintenance.

Applications: Off-grid villages, developing regions, emergency cold chain operations, mobile medical camps
Advantages: Renewable energy source, reduced carbon footprint, portable and scalable

🚛 5. Containerized Cold Rooms: Mobility Meets Efficiency

For clients seeking flexible, plug-and-play cold storage, Focusun’s Containerized Cold Rooms offer mobility, fast deployment, and robust performance. These units are built into 20-foot or 40-foot shipping containers, pre-installed with insulation, refrigeration systems, and electrical controls.

They are ideal for temporary storage at construction sites, mobile seafood markets, disaster relief, or expanding storage capacity during peak seasons. All systems are factory tested, ensuring immediate readiness upon delivery.

Applications: Pop-up distribution centers, seasonal cold storage, logistics backup, disaster relief
Advantages: Easy relocation, modular expansion, plug-and-play installation, weather-resistant design
