55-250kW DIRECT ROTARY SCREW AIR COMPRESSORS Our most energy-efficient air compressor to date, the NxHE Series compressors use patented two-stage airend technology to provide efficient operation with outstanding durability and offer the lowest life-cycle cost of any compressor on the market. Description TWO-STAGE COMPRESSION: SETTING THE STANDARD FOR ENERGY EFFICIENCY Compared to single-stage rotary screw compressors, a two-stage is much closer to isothermal compression. This is achieved by injection of fresh oil between the stages which reduces the inlet temperature to the second stage. This lower inlet temperature increases efficiency by reducing the compression ratio between the stages. In addition, leakage between the rotor seals is significantly reduced resulting in outstanding volumetric efficiency. Two-stage air compressors are closer to the ideal isothermal compression: • Reduced leakage increases volumetric efficiency • Saves 10-15% of energy compared to single-stage compressors • Increases flow 10-15% compared to single-stage compressors • Lower pressure differential increases efficiency and reliability • Low heat load • Easy maintenance and service • Lowest life-cycle cost of any compressor on the market eCOOL® TECHNOLOGY The ultimate in system protection and reliability • Protects critical components from compressor-generated heat • Compartmentalized air flow design and oversized aftercooler • Extends component life and reduces downtime ENERGY EFFICIENT TWO-STAGE AIREND Energy-saving and Eco-friendly • Patented airend design integrates the first and second stage rotors into one airend • Oil is injected between the first and second stages to cool the air and optimize efficiency • Splitting the compression cycle into Two-stages reduces the axial and thrust loading to which improves service life of airend and bearings • Two-stage compression significantly reduces noise EFFECTIVELY INTEGRATED OVERALL DESIGN Designed for low cost of ownership, easy service & little down time • Safe, efficient air filter system • Independent bearing lubrication • High efficiency, easy-to-maintain oil separator • IE3 high efficiency motor • End face sealed to prevent leakage • Connections utilize o-ring face seals for leak–free performance • Asbestos-free gaskets protect operator health

40 Bar, Oil-Lubricated, Booster Compressor Compressed air is an energy source that is as important as electricity and hydraulics. Especially for the production of pet bottles, which are being used more and more in daily life, by people all over the world. Besides, the applications such as leak tests of hydraulic and pneumatic devices, specific drive cylinders, presses, and fixture apparatus also need high-pressure air. Unlike other applications requiring only low-pressure air, both low and high-pressure levels of air up to 40 bars ought to be used in the facilities for these applications. Therefore, instead of designing the whole system considering the high-pressure need, increasing the air pressure just at the certain points where high pressure is needed, is the most energy and cost-efficient solution. As a manufacturer having reciprocating booster compressors in its product portfolio which boost the 7-13 bar compressed air taken from rotary screw compressors, up to 40 bars, FS-Curtis provides the most appropriate solutions with its years of experience and quality policy to pet manufacturers and the enterprises which have to use high-pressure air. These compressors can also be modified to serve as boosters for nitrogen.
