Evaporator Refrigeration

The DSL-42.9/210 is a mega-scale double-outlet evaporator refrigeration unit built for large high-temperature cold storage facilities, including regional cold chain wholesale hubs and bulk fresh produce central warehouses. Equipped with four axial fans, a 210㎡ heat exchange area and 4.5mm optimized fin spacing, it delivers a steady 42900W cooling capacity, effectively eliminating cold dead spots and ensuring even temperature distribution across every corner of oversized storage spaces.

Energy expenditure makes up a large portion of recurring costs for large high-temperature cold storage facilities. Conventional air coolers typically deliver lower heat transfer efficiency and run higher energy consumption due to suboptimal fin design and frequent extended defrost cycles. This evaporator refrigeration unit adopts 4.5mm aerodynamically optimized fin spacing to cut airflow resistance, paired with high-purity copper heat exchange tubes to maximize thermal efficiency. Its balanced dual-circuit defrost system also minimizes energy waste during defrost cycles, helping operators significantly cut long-term electricity expenses.

Cold storage facilities handling fresh produce or located in coastal regions often struggle with coil corrosion and moisture-related component failures, which increase maintenance workload and cause unexpected downtime. This evaporator refrigeration unit features anti-corrosion treated aluminum fins, fully sealed fan motors and a moisture-resistant cabinet structure. It maintains stable, consistent performance even in high-humidity storage environments and salt-spray coastal areas, extending equipment lifespan and reducing overall maintenance investment.
