Description
DJ140 Robust Quick Freezing Cold Room Evaporator
DJ-23.9/140 is a professional ceiling air cooler designed for -25℃ large-scale quick-freezing workshops for meat and aquatic products. It features 23900W nominal cooling capacity and 140㎡ heat exchange area. Adopting DJ series standard 9mm wide fin spacing, the unit effectively resists heavy frost accumulation in high-humidity environments, reduces frequent defrost shutdowns and ensures stable continuous operation for mass production.
Oversized quick-freezing warehouses easily suffer from temperature stratification and local poor refrigeration. Equipped with four large-diameter low-temperature resistant axial fans and optimized streamlined ducts, this unit delivers large air volume and long air supply distance. It achieves full-space cold air coverage, balances indoor temperature and guarantees uniform freezing quality of bulk goods.
The whole machine adopts high-quality steel plate with electrostatic spraying for excellent anti-corrosion performance. The heat exchange coil is processed by precision mechanical tube expansion to make copper tubes closely fit with aluminum fins. All finished products pass strict nitrogen pressure test before delivery, effectively preventing refrigerant leakage and extending the overall service life of the equipment.
