Oil Free Rotary Screw Air Compressor
Model - DH15VSD-A ~ DH22VSD-A
DH series water lubricated rotary screw compressor
DH15VSD-A ~ DH22VSD-A
The DH series contains absolutely no oil, no matter where the compressor is used, and is ISO 8573-1 Class Zero (2010) and silicon-free certified.
The unique design allows for lower speeds and cooler operating temperatures - both contributing to increased efficiency and reduced component wear. A single-stage direct drive motor with no gears or belts maximizes efficiency. Using variable speed technology to limit compressed air to application demands ensures that no energy consumption is wasted.
• Single-stage direct-drive compressor element maximizes efficiency and reduces maintenance
• Premium water spray lubricates, cools and seals the compression process for maximum efficiency
• No gearbox means no need for associated oil lubrication
• Lower bearing loads and speeds mean permanently sealed bearings can be used without oil lubrication
• Variable speed technology available to reduce energy costs
• Comprehensive control functions ensure safe and reliable operation, including remote communication capabilities
• Fully sealed and sound-dampening enclosure reduces noise and simplifies installation
• Unique design allows for lower speeds and cooler operating temperatures - both for increased efficiency and reduced component wear. A single-stage direct drive motor with no gears or belts maximizes efficiency. Using variable speed technology to limit compressed air to application demands ensures that no energy consumption is wasted.
• Compared to similar equipment, DH compressors have significantly fewer moving parts, which reduces the chance of failure, while lowering operating speeds, balanced bearing loads, and longer compression element life, resulting in lower operating costs.
• Can achieve ultra-low operating temperatures below 60°C with near isothermal compression. This also eliminates the use of an internal secondary cooler and associated energy consumption, reducing pressure drop to an even lower level.
• Balances compressive loads, reducing bearing loads for greater reliability:

• Tested reverse osmosis filtration provides high quality purified water to lubricate, seal and cool compression processes. Using an osmotic pump, the required water volume can be reduced to even lower levels.

DH series water lubricated rotary screw compressor DH55VSD-A/W ~ DH90VSD-A/W 100% air purity to meet stringent quality standards Unique design allows for lower speeds and cooler operating temperatures - both contributing to increased efficiency and reduced component wear. A single-stage direct drive motor with no gears or belts maximizes efficiency. Using variable speed technology to limit compressed air to application demands ensures that no energy consumption is wasted. Compared with the same type of equipment, the DH compressor has significantly fewer moving parts, which can reduce the probability of failure, while reducing the operating speed, balanced bearing load, and prolonging the service life of the compression element, thereby reducing operating costs. It can reach ultra-low operating temperature below 60°C near constant temperature compression. This also eliminates the use of an internal secondary cooler and associated energy consumption, reducing pressure drop to an even lower level. Balances compression loads, reducing bearing loads for higher reliability, and proven reverse osmosis filtration provides high-quality pure water to lubricate, seal, and cool the compression process. Using an osmotic pump, the required water volume can be reduced to even lower levels. Using a speed-regulated compressor can easily save 35% of energy because it only consumes the energy needed to get the job done. Multilingual control system ensures safe and reliable operation and protects your investment by continuously monitoring operating parameters which is essential to reduce operating costs.
DH series water lubricated rotary screw compressor DH110VSD-A/W ~ DH160VSD-A/W When you choose an oil-free DH series compressor, you choose a clean, reliable and economical air source, which can greatly promote your business development and ensure your profits! Air cleanliness is critical in many applications because even the smallest drop of oil can result in substandard product quality or damage to production equipment. It is for this reason that DH series compressors are truly oil-free, making them a better and safer choice for you without the risk of oil pollution. Energy efficient When the single-screw compressor is working, each screw groove on the screw is used twice in one rotation, The screw groove space can be fully utilized, so compared with other rotary compressors, its structure size is smaller. The groove depth of the single screw becomes shallower with the increase of the compression chamber pressure, and the depth is zero at the end of the exhaust, Therefore, in theory, there is no clearance void product. Using water as the coolant, the temperature of the main engine is lower during the compression process, the efficiency is higher, and the energy saving effect is remarkable. Safe and reliable A screw and two left and right star wheels form 12 compression chambers, and 12 air compression processes are generated by one rotation. The two star wheels of the single-screw air compressor are symmetrically distributed on both sides of the screw, which ensures the balance force, and the axial force and radial force acting on the screw can cancel each other, effectively restraining the vibration source. The force of the rotor is balanced, the pulsation is small, the vibration is small, the performance is more reliable, and the service life is longer. Efficient host Pure water is directly injected into the compression chamber for cooling, no oil coolant is used, and truly oil-free compressed air The head rotor is made of stainless steel and will never rust The bearing adopts high-end special ceramic bearing to ensure the reliability of water lubrication, high efficiency and low noise The main engine has no metal and metal meshing parts, the rotor is balanced in force, stable and reliable, and has a longer life Rare earth permanent magnet variable frequency motor DH series water-lubricated oil-free screw compressors are driven by rare earth permanent magnet variable frequency motors. Compared with AC asynchronous motors, rare earth permanent The magneto has a simple structure, reliable operation, high power density, and a wide range of speed regulation. It is an ideal power choice for high-efficiency and energy-saving air compressors. Frequency conversion advantage Ordinary air compressors usually adjust the air volume by adjusting the air intake of the air compressor. This method keeps the air compressor running at the rated speed. Even if the air volume is reduced, the actual energy consumption will not decrease proportionally. The displacement of the variable frequency air compressor can be perfectly combined with the air consumption of the user When purchasing an air compressor, the traditional cost (ie purchase cost and operation and maintenance cost) only accounts for 20% of the total cost, while energy consumption accounts for 80%. Save at least 30% energy compared to machine
