Our high pressure booster compressors are available up to 40HP.
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

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.

Capacity : 40 cfm to 10,000 cfm
Working Pressure : 4.5 to 70 bar(g)
Need of Compressed Heatless Air Dryer
Compressed air leaving the compressor contains considerable quantities of water vapour, oil particles. If the untreated air is supplied to distribution lines, then the moisture would condense to liquid water as it gets cooled. The condensed water is a major cause of downtime in compressed air systems as it causes rust, pitting, blockages and freeze ups, which result in component failure and product rejection. The only way to prevent condensation of water in air lines is to lower the dew point of the air in the system. It is less expensive to own and operate an air dryer than to live with the problems.
Adzorb Heatless Air dryer Operation
Coalescing filters of 5 micron and 0.01 micron remove bulk moisture and liquid oil from the compressed air. This pre-treated air diffuses to the bottom of the adsorber (T1) and passes through the desiccant bed which adsorbs moisture and dries the air. Dry air leaves the adsorber (T1) and passes through 1 micron dust filter. Thus dry, filtered compressed air is available for precise operation.
The desiccant can adsorb only certain quantity of moisture and will reach equilibrium after certain time. It can no longer dries the air to the required dew point and hence it should be regenerated to keep the process continuous. To regenerate the first adsorber (T1), partial quantity of dry air coming out of second adsorber (T2) is diverted to first adsorber (T1). This dry air expands to atmospheric pressure and becomes subsaturated. This subsaturated dry air purges out all moisture from the first adsorber (T1) and makes it ready for next adsorption process. All these operations are perfectly performed by valves and controller.
