FUSHENG Single Machine Double Stage Screw Parallel Unit

FUSHENG Single Machine Double Stage Screw Parallel Unit

Compressor brand: FUSHENG (Taiwan)

Fusheng is one of the world's largest compressor manufacturers, with over a dozen compressor production plants across Asia, the Americas, Australia, and Europe.

The group includes: the world's first inventor of centrifugal air compressors, the U.S.-based ELLIOTT Centrifugal Compressor Division founded in 1895;

FS-CURTIS, a historic American compressor leader founded in 1854, is now a leading screw air compressor manufacturer in the United States.

Fusheng's compressor series covers centrifugal, screw, scroll, and piston types, with applications spanning industrial, military, and engineering fields.

Applications in refrigeration: ultra-low temperature cold storage, quick-freezing cold storage, and refrigeration source matching for quick-freezing machines (significantly reducing operational costs for ultra-low temperature refrigeration applications)

Product features:

1. Model selection is flexible

(1) Applicable evaporation temperature: -60°C to-32°C

(2) Recommended optimal cold storage temperature: -45°C to-50°C

(3) Compatible with multiple refrigerants: R507A, R22, R404A

(4) 60HP-1080HP, with a maximum cooling capacity of 513KW (based on a cold storage temperature of-60℃)

2. Stable and reliable operation

(1) The unique constant regulation system with low environmental condensation pressure prevents liquid supply shortage or oil flow alarm caused by low ambient temperature, ensuring stable system operation.

(2) The high efficiency gas-liquid separation device and the unique pipeline design can avoid the possibility of liquid hammer in the compressor.

(3) Each unit comes with a full set of safety protection modules by default, covering phase loss, reverse phase sequence, overvoltage, undervoltage, oil pressure, high voltage, low voltage, and motor overload, along with control systems that effectively prevent frequent start-stop cycles.

(4) Each unit comes with a PLC controller as standard, which automatically adjusts the number of compressors in operation based on cooling demand, balances the runtime of individual compressors, and reduces energy waste, extending the unit's lifespan by over 30% compared to standalone units.

3. Use energy-efficient solutions

(1) As the cooling demand varies significantly across different seasons throughout the year, the unit must possess high capacity control capability to maintain efficient operation in response to load fluctuations. The average efficiency of parallel units is 30% higher than that of single-unit systems, depending on the refrigeration system configuration.

(2) Multiple compressors operate in parallel, enabling multi-stage energy regulation. This allows the cooling output to dynamically and smoothly match the actual load.

(3) The PLC controller automatically adjusts the number of operational units based on the return gas pressure, ensuring maximum efficiency even under partial load conditions.

(4) The PLC controller can configure optimal operating curves (covering peak and off-peak grid conditions), significantly reducing energy consumption for end-users.

4. Compact and agile structure

(1) All components including compressor, receiver, gas-liquid separator, oil separator, economizer, return gas manifold, liquid supply manifold, and electronic control equipment are integrated to maximize space efficiency in the machine room.

(2) The compact design of the unit reduces installation space, providing users with more commercial space and further creating value for end-users.

5. Simple and convenient operation

(1) The PLC features secure automatic control with a Chinese touchscreen menu and intuitive graphical interface, providing real-time device status display, data logging, parameter adjustment, and fault alarms.

(2) Equipped with a remote communication interface for convenient off-site monitoring by customers. Includes a print output port for printing historical records of unit and system operations.
