Description
Oil-Free Screw air compressor through two screw rotors to compress air, then through the water-air separator to remove water from the compressed air. At the same time, because there is no oil injection cooling, usually to cool the compressed air with equipped pre-cooler, intercooler, aftercooler, to meet the requirements of the outlet temperature. In the rotor shaft through the high-performance shaft seal to prevent leakage of lubricating oil into the Compressed air, to achieve oil-free.
Why Choose United Oil-Free Screw Air Compressor
High Efficiency and Energy Saving
· Hitachi technology - a better explanation of the logical function of energy saving.
· TUV Certified Class 0
The Optimized Operating System
· A FEATURE-RICH ITCS controller makes the operation more labour-saving and timesaving. A simple connection allows for joint control of 2 air compressors.
· Multiple Air compressor centrally controlled through several controllers.
Thermosetting Coating
The surface of the rotor and the inner wall of the air end housing coated with the thermosetting coating of molybdenum disulfide. Which effectively prevent corrosion and reduce internal leakage by controlling the clearance.
Easy Maintenance
Easy maintenance and long interval cycle.
Caring for The Environment
Oil mist cleaner as standard configuration can relieve the pressure inside the gearbox and ensure the cleanness of the workshop.
Low Noise
Pulsating noise reduction and improved sound quality.
Industry Applications
Food and Beverage Industry
The high-temperature compression environment of oil-free air compressor reduces the content of microorganism in the compressed air. Besides, no oil brought into the entire compression process, which significantly reduces the risk of contamination of food and beverage products in the production process.
The Pharmaceutical Industry
The demanding pharmaceutical industry uses 100 per cent oil-free compressed air throughout its manufacturing process. The quality of compressed air is an essential part of GMP certification.
The Chemical Industry
For applications in the chemical industry, high purity compressed air must be used at every step of the process, from the first step of the production process to the semi-finished products and the final product formation, to minimize the risk of stop-production.
The Power Industry
The quality of the compressed air is critical and must not neglect. When the compressed air applies to the instrument of the power system, most designers will choose oil-free air compressor.
Core Strengths of United Compressor
Hitachi Designs
Dry compression as no lubricating oil in the compression chamber and the compressed air is 100% oil-free. The shaft sealing ring is stainless-steel which does not generate carbon dust.
Hitachi Air End
Imported original Hitachi air end to ensure high quality and high performance.
Efficient Two-Stage Compression
The lowered specific power of the two-stage compression improves the cooling performance, reduces the internal compression management, increases performance by 5-10%.
Dry Oil-Free Technology
Since United oil-free screw air compressor came into the market, more than 100,000 pairs of oil-free rotors have produced and applied to all walks of life, mostly pharmaceutical, food and beverage, electronics and those industries with high requirements for compressed air quality.
