DJ-8.9/55 is engineered for medium-large aquatic & meat ultra-low temperature quick-freezing workshops with design temperature at -25℃. Equipped with 8900W rated cooling power and 55㎡ nominal heat exchange area, it features exclusive 9mm wide fin spacing specially tailored for heavy-frost high-humidity environment, slowing frost accumulation speed and reducing frequent stop-for-defrost downtime to sustain uninterrupted batch freezing production.

 

Conventional mid-size quick-freeze rooms often suffer upper-lower temperature difference and local incomplete freezing caused by unreasonable airflow layout. This unit matches two Φ500 low-temperature resistant axial fans and streamlined inner flow guide structure to realize homogeneous cold air coverage across the whole chamber, shortening product core freezing cycle and improving finished product qualification rate.

 

All aluminum fins adopt hydrophilic anti-corrosion coating treatment while outer shell goes through high-temperature electrostatic plastic spraying; seamless copper coil undergoes anti-oxidation pre-treatment as standard craft. The layered anti-corrosion structure effectively resists salt mist and condensed water erosion in damp seafood processing environment, greatly prolonging whole machine service cycle and cutting later-period corrosion maintenance cost.
