Variable-frequency Screw Refrigeration Unit
High-efficiency variable-frequency screw compressors; energy-saving and stable
View Details →Model: ANC-K Series (25 HP – 60 HP)

Water-cooled units built with German Bitzer low-temperature semi-hermetic screw compressors for duties from -35°C to -20°C (low-temperature rooms, blast freezers, ice making); single, dual and triple parallel configurations with economizers, oil separators and oil coolers for stable performance.
Medium/low-temperature screw units built with German Bitzer low-temperature semi-hermetic screw compressors, widely used in low-temperature rooms, blast freezers, ice-making equipment and freezing processing; evaporating temperature -35°C to -20°C using R22.
Model numbers begin with ANC, e.g. ANCDJ25DF: ANC is the brand identifier, DJ denotes a low-temperature single screw unit, 25 indicates horsepower, D denotes low temperature, and F denotes air-cooled condensing (S for water-cooled); dual parallel series include 2BL and triple parallel series 3BL.
Low-temperature screw compressor, oil separator, oil cooler, oil circuit components, condenser (water-cooled units only), liquid receiver, liquid-line filter, sight glass, economizer assembly, suction filter, pressure protectors, pressure gauges and control box (PLC + touchscreen).
German Bitzer low-temperature screw compressor with high efficiency, long life, low vibration and low noise;
Fully configured with world-renowned refrigeration components and control elements for high reliability;
Multiple safety protections including reverse rotation, overheating, overload, discharge temperature, low oil level and high/low pressure ensure reliable operation;
Equipped with an economizer to significantly boost cooling capacity in low-temperature duty;
Multi-stage capacity control (50–100%) adapts to load changes and effectively reduces energy use.
Meat freezing, seafood quick freezing, industrial freezing, low-temperature warehousing, ice-making, quick-freeze processing and logistics cold chains.
See the technical specification table below (compressor parameters, cooling capacity and power matrix, installation parameters and condenser parameters).
