This coolroom unit is engineered for medium-temperature cold rooms above 8℃ with an area of approximately 100㎡. It is ideally suited for fresh food distribution warehouses, food processing workshops, and central kitchen ingredient storage areas.

The unit features external rotor motors with a dual-outlet air structure that delivers soft, even cold air distribution rather than direct strong blasts on goods. This design effectively reduces dry loss of fresh vegetables, fruits, and raw ingredients, helping maintain their original texture and quality.

With low noise operation and three fans supporting bidirectional airflow, the unit covers a wider range and minimizes temperature dead corners near shelves and warehouse corners.

Inside the unit, staggered copper coils are processed with mechanical tube expanding technology, ensuring tight contact between copper tubes and aluminum fins for optimal heat exchange and stable cooling output.

The specially optimized 6mm fin spacing for medium-temperature conditions above 8℃ slows frost accumulation, reducing defrosting cycles and temperature fluctuations. Even with frequent door openings for replenishment and picking, the unit quickly restores temperature to the set range, maintaining a stable storage environment.

The aluminum alloy shell with plastic-sprayed surface offers excellent corrosion resistance and maintains a neat appearance in humid cold storage environments. The smooth surface resists dust and dirt accumulation, facilitating simple and efficient daily cleaning and disinfection—meeting the stringent hygiene requirements of food processing and storage scenarios.

The ceiling-mounted design conserves valuable floor space, while side-mounted inlet and outlet ports accommodate most conventional cold room pipeline layouts. Suitable for both new construction and renovation projects, the unit features relatively easy on-site installation.

For larger cold storage spaces of 120㎡ and above with higher refrigeration demands, consider the DSD-22.3/120 heavy-duty dual outlet coolroom unit for larger-capacity selection. Browse our full series of ceiling-mounted medium temperature air coolers for additional model options.
