Oil Free Rotary Compressor

Atlas Copco is renowned for designing and manufacturing some of the most durable oil-free screw compressors.The ZR/ZT high-end rotary screw compressor comes out of this strong tradition. Ideal for industries where high-quality oil-free air is key, the ZR/ZT offers the highest reliability and safety in combination with extremely low energy costs. Core technology:Atlas Copco masters each compression principle and offers the most energy efficient technology for the application. Fixed speed machines are efficient at full load but when air demand fluctuates, a Variable Speed Drive ensures substantial savings.The integrated adsorption dryer offers high quality dry air with the lowest pressure drop and uses the heat of the compressor for regeneration.Two features that lead to significant energy savings. Optimal use:Central control of a multi-compressor installation reduces the pressure band and achieves the lowest overall energy cost. Heat of compression can be recovered and put to good use in industrial processes like pre-heating of boiler feed water, heating of buildings etc. Oil-free compression:Our oil-free screw compressors have compressor chambers completely free of oil.This is possible because there is no metal contact between the precision cut rotors and hence no need for lubrication. Process, products and environment are safeguarded from contamination.The first air compressorsTUV-certified as "oil-free" (ISO 8573-1 CLASS 0). The integrated design:Internal piping, high end design features, Variable Speed Drive, 100% matched components... the only way to ensure total reliability. Each machine is tested to ensure it meets specifications, complete security and no surprises.The ZR/ZT oil-free compressor is truly plug-and-play. Put it on a flat floor, connect the power line and the air outlet and push the start button.
