The DJ-3.4/20 ceiling type air cooler is a medium-temperature evaporator designed for food cold rooms, fresh produce warehouses, and commercial cold storage applications. Delivering stable 3400W cooling capacity and uniform airflow distribution, it maintains consistent storage temperatures while reducing product dehydration and temperature fluctuations, meeting the reliable refrigeration needs of food processing plants and cold chain logistics projects.
Food and fresh produce stored in medium-temperature cold rooms are highly sensitive to unstable temperatures and uneven cooling. Poor airflow distribution can lead to partial frost buildup, increased energy consumption, and accelerated product spoilage. The DJ-3.4/20 air cooler is engineered to provide balanced airflow throughout the cold room, helping to extend product shelf life and maintain consistent quality.
This unit adopts high-quality copper heat exchange tubes and optimized fin structure, featuring excellent anti-corrosion and rust-proof performance to adapt to long-term high-humidity working conditions in cold rooms. It supports mainstream environmental refrigerants and matches standard refrigeration systems with ceiling installation for space saving. The overall structure is simplified for easy daily cleaning and routine maintenance, running stably with reasonable energy consumption in daily operation.
