Introducing the UCS Variable Speed Permanent Magnet Drive Low-Pressure Series Screw Air Compressor, a revolutionary solution designed to meet the growing demand for energy efficiency, emissions reduction, and environmental protection. This innovative compressor eliminates the need for traditional high-pressure compressors that decompress compressed air before transmission, resulting in significant energy savings.
Our industry-leading low-pressure screw air compressor boasts the lowest exhaust pressure in the market, reaching 1.2bar, while ensuring an ultra-low oil content of less than 2ppm for a clean and stable air supply. The enclosed cabinet low-noise design offers a more environmentally friendly alternative to conventional piston compressors.
With a focus on reliability, the UCS Variable Speed Permanent Magnet Drive Low-Pressure Series is designed for industries that require continuous operation without downtime. Our compressors ensure easy maintenance during operation and are equipped with fault alarm systems for comprehensive emergency preparedness, guaranteeing stable and dependable performance.
Upgrade to the UCS Variable Speed Permanent Magnet Drive Low-Pressure Series Screw Air Compressor and elevate your operations with an energy-efficient, environmentally friendly, and reliable compressed air solution that meets the diverse needs of today’s industries.
· Can save more than 30% of the electricity;
· The low-pressure air end can automatically adjust the internal compression ratio according to the service pressure and maintain the best energy efficiency within the exhaust pressure range of 2-5bar;
· In many industries, such as chemical, glass, petroleum, textile, printing, dyeing, and ceramics, the required working pressure of compressed air is only 3-5bar. However, at present, these industries usually use 7-10bar air compressors coupling with a pressure reducing valve to achieve low pressure; it is undoubtedly a considerable waste of energy. For this reason, UCS has developed low-pressure screw air compressor which directly outputs the low-pressure compressed air required by these industries; the compressor uses less energy to meet the production requirement, and user’s production cost will significantly improve.
· International leading moulded lining, 4:6 tooth ratio, less tooth and more air suction;
· Large rotor, low speed, and long life;
· The inner oil circuit of the air end can precisely control the amount of oil injection, helping the lubrication and cooling reach the best performance;
· SKF bearings adapted to the load changing, which is flexible, efficient, proven long durability, and it guarantees the life of the air end.
· 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.
Prevent large particles of dust, cotton and other sundries from entering the air compressor. Keep the compressor internal clean. Strictly observe the first pass of compressed air.
Heavy-duty air filtration system powered by Donaldson USA, with filtration accuracy up to 99.9% for particles greater than 3μm. Suitable for all kinds of heavy dust environments.
The pressure difference of all air path less than 0.2bar, greatly extending the service life of the air filtration system.
Low energy consumption in no-load operation, cast aluminium material, more stable performance.
High strength rubber sealing, firm and durable.
Donaldson oil filters, high grade of clean filtration, effectively protect the safe operation of the air end bearing, extend the service life of the air end.
Euro design efficient oil and air separation core, glass fibre filter material, long life, more efficient, no need for frequent replacement. The aggregate separation core and the oil return device work together, recover and recycle the lubricating oil effectively, avoiding oil over-spraying, and ensuring the oil content of the compressor exhaust ≤2ppm.
UCS lubricating oil has good oxidation resistance, high-temperature resistance, high flash point, excellent thermal conductivity and many other characteristics.
· 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.
· 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 180°C;
· 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 protects 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.
The excitation system loss eliminated, improving efficiency.
The energy efficiency of the PMSM is more than 9% higher than the asynchronous motor and remains unchanged with the reduced frequency.
The maximum starting torque of the PMSM may up to 3 times higher than the rated torque, while the general asynchronous motor has 1.6 times only.
The PMSM response time less than 50ms. The air production volume may be adjusted transiently within a broad range to stabilize air pressure precisely.
· 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.
