Cold Room Unit

Targeting the high-humidity, frost-prone pain points of food processing workshops, the DSD-7.0/40 cold room unit adopts 6mm widened fin spacing. Paired with a 40㎡ staggered heat exchange coil, it delivers a steady 7000W cooling capacity while greatly slowing down frost accumulation on the coil surface. Equipped with a 4800W coil defrost system and 2400W water tray defrost heater, each defrost cycle takes less time, effectively reducing maintenance frequency and production downtime, and lowering daily labor costs for continuous food processing lines.

The whole unit housing is made of powder-coated aluminum sheet, which is moisture-proof, corrosion-resistant and easy to wipe clean, fully meeting the hygiene management requirements of food processing workshops. The internal heat exchange coils adopt a mechanical tube expanding process to ensure tight bonding between copper tubes and aluminum fins, maintaining stable and efficient heat transfer for a long time. The fully enclosed external rotor fan motors resist moisture erosion, making this cold room unit suitable for long-term stable operation in medium-temperature scenarios above 8℃, such as fruit and vegetable sorting, cooked food cooling and dairy temporary storage.

With a double-outlet air supply structure, two φ400 axial fans deliver a total air volume of 6800m³/h, forming a three-dimensional circulating airflow inside the workshop. The soft air distribution avoids local temperature differences and direct cold wind blowing on ingredients, preventing water loss of fresh produce and over-cooling of cooked food that would affect taste. Its standard ceiling-mounted structure fits most workshop floor heights, and the universal φ19mm inlet / φ25mm outlet connections can be quickly docked with mainstream refrigeration systems, suitable for both new construction and retrofit projects.
