UCS two-stage variable speed (VSD/VFD) permanent magnet screw air compressor uses a permanent magnet synchronous motor, which does not need excitation current, high efficiency and no reactive loss. The speed of two-stage compression is high, and the air supply pressure range is vast and stable after frequency conversion. The most apparent advantages are energy-saving and large air production, air intake adjusted in real-time according to the air demanding, which ensures that the air compressor is running with higher efficiency.



Mechanic System

High Efficiency Air End

• Combining advanced rotor seal and fluid dynamics technology, also the efficient rotor line profile, which makes the rotors have high thermal insulation efficiency at all levels so that each air end to achieve better performance;
• Using bearings with larger bearing capacity, and the mounting and preloading of the bearing precisely calculated so that the reliability is improved, and the service life of the bearing extended;
• The casing of the air end adopted the unique form-position tolerance evaluation system and high-precision numerical control machine (CNC) processing technology, strictly controls the internal clearance of the air end so that the air end has high efficiency while maintaining high reliability;
• The air end has higher comprehensive adiabatic efficiency by adopting two-stage compression and inter-stage cooling, to realize the purpose of energy-saving;
• Compared with single-stage compressor, the two-stage compressor can save energy up to 10%-25%.

Low Pressure Screw Air End Drive Chain

• The high-efficient driving motor directly connected to the two-stage compression air end without coupling, the transmission chain is maintenance-free, reducing energy consumption by 1%;
• IP55 fully closed motor and air end housing integrated, effectively prevents metal particles, dust, moisture and other pollutants infiltrating into the motor and air end, makes the compressor performance more stable;
• The motor bearing uses strengthened cylinder + ball bearing, delivering higher strength and reliability;
• The machining accuracy of transmission gear up to aviation level 6, multi-channel heat treatment and related processing technology ensure the superior surface hardness, ultra-high wear resistance and yield strength of all mechanical components;
• Independent oil supply system and precise oil filtration effectively ensure the stability and reliability of the entire transmission under the long-time operation of full load.

Lubricating Oil:

UCS lubricating oil has good oxidation resistance, high-temperature resistance, high flash point, excellent thermal conductivity and many other characteristics.


Cooling System:

• The design allowance of heat exchange is 20%-50%, which ensures the stable operation of the compressor in an extreme environment and minimize pressure drop.
• Standard motor frequency conversion, accurate oil temperature control, further reduce air compressor energy consumption.

Features of Permanent Magnet Synchronous Motor (PMSM)

• The motor efficiency is as high as 96%, and the power factor is 0.98, far exceeding the level 1 energy efficiency standard;
• Permanent magnet with high coerce and high-temperature resistance ensures no demagnetization at a high temperature of 180ºC;
• Independent fan cooling , to ensure the motor safe running under long hours and low frequency;
• F grade insulation, 70K temperature rise design, suits the high temperature working condition of air compressor ;
• Fully enclosed IP55 protection projects the clean internal environment of the motor and extends the life of permanent magnet and insulation;
• Built-in temperature protection protects winding insulation and permanent magnet.

Features of UCS VFD Speed Regulation PMSM Air Compressor 

• Ultra-low temperature rise design, to allow compressor long-term low-frequency stable operation;
• Adopting the open-loop vector control system, it controls faster, and the speed regulation is more accurate;
• When the frequency is reduced by more than 50%, the compressor unit can still operate efficiently;
• Stable pressure accurately controls pressure fluctuation within 0.01mpa; With soft-start characteristic, avoid start current shock, reduce start energy consumption.

UNITED COMPRESSOR SYSTEM has a series of screw compressors with the power of 5.5~630kW, FAD of 0.69~120m3/min and pressure range of 0.2~1.5MPa. At UCS, we also provide services such as design, manufacturing, training operation of the air compression station, technological improvement of energy-saving and customized types. The idea of wholeheartedly customer serving makes our pace steady and long.

To save space and install pipelines, the series of intelligent all-in-one screw compressor produced by UCS integrates compressor, air storage tank, refrigerated dryer and filter into one unit, which is equivalent to a miniature air compressor station. The machine popularly used in dentistry, hyperbaric oxygen chamber, laboratory, electronics, semiconductor, winery, beverage, food packaging, laser cutting, and other industries were requiring pure air and small-scale air supply.

Quality Assurance

In 2003, UCS Compressor accredited with ISO9001 Quality Management System and ISO14001 Environmental Management System Certificates. The company strictly follows the quality requirement of Crosby's "doing it right the first time", persists in the working standard of "zero defect", regards the "It is immoral to produce a defective product" as the criteria of measuring the quality. UCS devotes itself to the continuous improvement of products all the time.
