Cold Room Cooling Unit
Product Overview
The DSD-3.7/22 dual outlet cold room cooling unit is a compact refrigeration device specially designed for small food processing workshops, fruit and vegetable fresh-keeping rooms, and commercial kitchen cold storage with an area of approximately 22㎡. With a nominal cooling capacity of 3700W and two 350mm external rotor fans delivering 2×2290m³/h bidirectional gentle airflow, it achieves uniform temperature distribution in small spaces without strong direct cold air blasting, maintaining stable storage conditions above 8℃ and preserving the original quality of fresh ingredients.
Key Advantages
Small food processing workshops and fresh-keeping operation areas generally face three easily overlooked operational challenges: frequent personnel movement and heat dissipation from processing equipment cause continuous local temperature fluctuations that affect ingredient processing quality; single-outlet cooling equipment with strong airflow accelerates water loss of fresh ingredients and reduces product taste; excessive equipment operating noise interferes with the on-site working environment.
This cold room cooling unit adopts a double-sided soft air supply structure matched with low-noise external rotor motors, which balances regional temperature while avoiding direct air blowing on ingredients, maintaining a quiet and comfortable operation environment for the workshop.
Food Processing Adaptation
In terms of adapting to food processing scenarios, this cold room cooling unit features an aluminum alloy shell with plastic spraying treatment, providing excellent corrosion resistance and a smooth surface that resists dust and dirt accumulation, meeting the hygiene requirements of food operation workshops. The 6mm fin spacing design reduces frost accumulation under working conditions above 8℃, and the flat fin surface facilitates regular cleaning and disinfection, effectively preventing bacterial growth caused by dirt accumulation and adapting to the long-term humid operation environment of food processing.

Frequently Asked Questions
Q: Is this dual-outlet cooling equipment suitable for installation in food processing workshops?
A: Yes. Its aluminum shell with plastic spraying treatment has good corrosion resistance and a smooth surface that is easy to clean and disinfect, which can meet the hygiene requirements of food operation and processing scenarios, and is very suitable for temperature control in food processing workshops and fresh-keeping operation areas.
Q: What benefits does the soft bidirectional air supply bring to ingredient storage and processing areas?
A: The gentle two-way airflow avoids direct cold air blasting on fresh ingredients, effectively reducing water loss and dry consumption of vegetables, fruits and fresh meat; at the same time, it will not cause strong cold discomfort to on-site operators, creating a more comfortable working environment.
Q: Is an additional defrost heater required when the storage temperature is above 8℃?
A: This model can operate normally without additional defrost heaters when the storage temperature is above 8℃. If the storage temperature is lower than 8℃, it is recommended to install a matching electric defrost heater to ensure stable and efficient long-term operation of the equipment.
Q: Do you provide OEM customization services for this refrigeration equipment?
A: Yes, we support OEM services including LOGO printing and multi-language nameplate customization for all our refrigeration products.
Q: What information is needed to get an official detailed quotation?
A: We will send you the quotation within 8 hours after receiving detailed parameters including refrigeration capacity, voltage, refrigerant and working conditions.
