Variable-frequency Screw Refrigeration Unit
High-efficiency variable-frequency screw compressors; energy-saving and stable
View Details →Model: ANC-K Series (ANC3BL30DS – ANC3BL70DS)

Water-cooled condensing units built with Frascold semi-hermetic screw compressors for low-temperature duties from -35°C to -20°C; wide evaporating range, high capacity and reliable operation.
Water-cooled condensing units (Frascold screw series, triple parallel) built with Frascold semi-hermetic screw compressors; evaporating temperature -35°C to -20°C using R22, with 50–100% capacity control.
Model numbers begin with ANC, e.g. ANC30DF: ANC is the brand identifier, the number indicates the size, D denotes a screw compressor, F denotes air-cooled condensing (S for water-cooled), and the 2/3 prefix denotes the number of parallel compressors.
Semi-hermetic screw compressor, crankcase heater, condenser, liquid receiver, oil separator, gas-liquid separator, filter, solenoid valve, pressure controller, pressure gauges, pipe connections and PLC control system.
International-brand screw compressor with low vibration, high efficiency, low noise and long service life;
50–100% stepless capacity control with excellent part-load performance;
Fully configured for rapid cooling and stable operation;
Customizable to individual requirements;
Wide range of applications; robust structure and compatible with multiple refrigerants.
Meat freezing, seafood quick freezing, industrial freezing, low-temperature warehousing, brewing, mushroom cultivation and logistics warehousing.
See the technical specification table (cooling capacity and power matrix, compressor parameters, installation parameters and condenser parameters).
