Description
RFJ Large-airflow DD-22.3/120 Air Cooler for Large Cold Storage
DD-22.3/120 overhead evaporator is developed for large-scale industrial frozen warehouses and centralized food cold chain facilities running at -18°C. With 22300W rated cooling capacity and 120㎡ heat exchange area, it supplies stable uniform refrigeration to reduce goods dehydration and constant temperature fluctuation, ideal for large meat processing plants and wholesale frozen storage projects.
Large-size cold rooms commonly face uneven air circulation leading to partial over-freezing or insufficient cooling and shortened shelf life of stored commodities. Optimized multi-fan matching and internal flow channel of DD-22.3/120 realize full-space balanced airflow, efficiently fix temperature stratification trouble and preserve original freshness of frozen products.
This evaporator features standardized pipe interface and internal coil layout, which is compatible with R22, R404A, R507 and multiple low-GWP environment-friendly refrigerants. It can perfectly mate with semi-hermetic and scroll compressors from mainstream brands, greatly improving flexibility for customers' existing refrigeration system upgrading.
