DJ-5.1/30 is purpose-built for -25℃ ultra-low-temperature blast freezing workshops of aquatic and fresh meat processing plants, delivering steady 5100W rated cooling power with 30㎡ nominal heat exchange area. Adopting DJ exclusive 9mm wide fin spacing, the unit effectively prevents fin blockage from dense frost under continuous high-humidity freezing surroundings, sustaining uninterrupted long-cycle production without frequent shutdown for defrost.

 

Medium-sized quick-freeze chambers frequently suffer uneven cold circulation leading to inconsistent core temperature of raw seafood and meat. Equipped with two Φ400 low-temperature resistant axial fans and streamlined internal flow channel layout, this evaporator forms concentrated directional cold airflow to shorten freezing cycle and eradicate local under-freezing defects in compact freezing space.

 

The evaporator's inner-groove copper coil and standardized pipeline structure are pre-engineered to fit various refrigerants, covering traditional R22, R404A, R507 as well as new low-GWP eco refrigerants like R290 and R454C. It can seamlessly match semi-hermetic piston and scroll compressors, making it an ideal replacement option for old cold storage system renovation and cutting customers' equipment upgrading investment.
