This cold room indoor unit is tailored for medium-temperature cold rooms above 8℃ with an area of approximately 160㎡, perfectly suited for large food processing raw material warehouses, fresh produce distribution hubs, and central kitchen bulk storage zones. Equipped with 4 external rotor motors and featuring a dual-sided air outlet structure, it delivers wide-coverage, soft and uniform cold air that avoids direct strong blast on stored goods. This effectively reduces dry loss of fresh vegetables, fruits, and dairy products while maintaining consistent freshness across all shelf positions. The low-noise operation ensures it will not disrupt the daily working environment even when installed adjacent to processing or sorting areas.

Inside the unit, staggered copper coils are processed with mechanical tube expanding technology, creating tight and seamless contact between copper tubes and aluminum fins for fully efficient heat exchange and stable cooling output. The 6mm wide fin spacing is specially optimized for medium-temperature working conditions above 8℃, effectively slowing down frost accumulation on the fin surface. This reduces the frequency of defrosting cycles, minimizes temperature fluctuations inside the cold room during defrosting, and maintains a stable storage environment even with frequent door openings during cargo loading, unloading, and batch sorting operations.

The cold room indoor unit features an aluminum alloy shell with a plastic-sprayed surface, providing excellent corrosion resistance and maintaining a neat appearance even after long-term operation in humid cold storage environments. The smooth surface is less prone to dust and dirt buildup, making daily cleaning and disinfection simple and efficient while meeting strict hygiene management requirements of food processing and storage scenarios. The standard ceiling-mounted design saves valuable floor storage space, and side-mounted inlet and outlet ports fit most conventional cold room pipeline layouts. It is compatible with both new cold storage construction projects and existing warehouse renovation projects, offering strong engineering adaptability.

A: Yes. The DSD-29.8/160 model is designed for around 160㎡ medium-temperature cold storage above 8℃. Its 4-fan dual outlet structure can achieve full and uniform coverage of large-span warehouses, which is very suitable for food processing raw material warehouses, bulk fresh produce storage and other medium-temperature scenarios.

A: Using one large-capacity dual-outlet unit saves more installation space and reduces pipeline connection points, lowering later maintenance costs. Its overall airflow distribution is more uniform, avoiding temperature differences caused by multiple independent units, and the operation is more energy-efficient under the same total cooling capacity.

A: The aluminum alloy base material has good rust and corrosion resistance, and the plastic-sprayed surface further enhances its adaptability to humid environments. It is not easy to peel or rust after long-term use, and the smooth surface is convenient for regular cleaning and disinfection, which can meet the long-term use needs of food-grade storage scenarios.

A: For standard models, bulk orders of conventional specifications can be delivered within 15-20 working days after payment confirmation. If the project has special customization requirements, the specific delivery cycle can be confirmed according to your actual needs.

A: We provide a 1-year standard warranty for all products. During the warranty period, we provide free replacement of defective non-human-damaged parts, and we also offer lifelong technical consultation and guidance, including installation guidance, daily maintenance training and fault troubleshooting support.
