Two-stage Screw Refrigeration Unit (Fusheng Compressor Series)

Product Overview

Two-stage screw units (dual parallel) built with two Fusheng semi-hermetic two-stage screw compressors for ultra-low-temperature duty from -60°C to -30°C using R404A, with 50–100% capacity control.

Model Naming

Model numbers begin with ANCS, e.g. ANCSDJ50DF: ANCS is the brand identifier, S denotes two-stage, DJ denotes a single screw unit, DF denotes air-cooled (evaporative) condensing; this series uses two parallel compressors.

Unit Configuration

Two two-stage semi-hermetic screw compressors, crankcase heaters, high-efficiency energy-saving evaporative condenser, liquid receiver, oil separator, gas-liquid separator, economizer, filter, solenoid valve, pressure controller, pressure gauges and PLC+HMI cabinet.
