75 Oil Free Water Injected Screw Compressor

At Atlas Copco, offload, we aim to provide you with compressors that fulfill and even exceed your expectations and demands. Built as the result of decades of experience in oil-less design and manufacturing, the AQ oil-free range of water-injected screw compressors gives you all of this experience and knowledge in a class-leading package.Variable Speed Drive:By automatically tuning compressor capacity to the precise air demand, only a minimum amount of energy is required, resulting in on average 35% energy savings.The inefficient transition period from full to no load power is eliminated and excoffloadpower consumption is avoided.High Efficiency:Filtering the water in the lubrication circuit, the water filter ensures. a constant supply of clean lubricant. Compared to external cooling systems, the installation costs of air-cooled units are extremely low thanks to the he air-air and air-water heat exchangers. Enduring Performance:Strength and durability are ensured thanks to the aluminumbronze element housing. The risk of corrosion within the element iseliminated.The hydrodynamic bearings ensure the long life as no physical contact is made within the bearing itself.Air filter: SAE fine 99.5%SAE coarse 99.9%Water filter:Filtering the water in the lubrication circuit, the water filter ensures a constant supply of clean lubricant. The filtration capability equals 10 microns throughout the filter's lifetime. Separator vessel: Stainless steel water separator vessel for separation via centrifugal and gravity forces. Two sensors (a low sensor and a high sensor) are included to maintain correct water levels. Induction motor: IP55 induction motor, flange-mounted for perfect alignment. Combined with the direct driven arrangement for superior energy efficiency.Air-cooled fan and water-cooler: The AQ is available as athe ir-cooled or water-cooled unit. Compared to external cooling systems, both the footprint and installation costs of air-cooled units are extremely low thanks to the air-air and air-water stainless steel heat exchangers. Incorporating a new, over-sized water-water exchanger, water-cooled units provide a virtually continuous air temperature at the dryer inlet of less than 55°C (131°F) without after cooler. Element bearings:No oil is used within the compressor element. Even the element bearings are water-lubricated, providing 100% oil-free air. The bearings are grease-free, eliminating any risk of contamination. As the bearings slide on the water, their lifetime is extended and a smooth rotation of the element is ensured. Reverse osmosis system:Using distilled water or reverse osmosis water for the water injection, the built-in reverse osmosis system ensures a constant supply of high-quality water, avoiding corrosion and bacteria growth.Water pump:Adding to the durability of the bearing, the water pump increases the bearing pressure level at startup and during offload. This minimizes energy consumption, eliminates stress on the bearings and balances pressure between the bearings and the rotor housing. Integrated refrigerant dryer:The Full Feature versions include an integrated refrigerant the dryer as standard. Sound insulated canopy:No separate compressor room is required as the sound insulated canopy allows for installation in most working environments.
