Oil-less Scroll Enclosure Systems

Now including systems up to 60hp!

Powerex has led scroll technology since 1991 when we introduced the first completely oil-less scroll air compressor. Our technology and expertise in clean, dry air systems is unmatched.

Powerex manufactures compressors, pumps, air receivers, control panels, air dryers, dew point monitors, and more, to provide a total system approach to your air compressor needs.

All facilities are ISO9001 registered so you can be assured of the highest quality. The enclosed scroll compressors feature compact footprints, energy efficient operation, low maintenance, and environmentally friendly design, all in one complete package.

OIL-LESS SCROLL TECHNOLOGY

Redundancy is built into our system with our multiple pump design, eliminating the need to purchase an additional compressor.

ENERGY EFFICIENCY

With the Powerex Variable-Pump- Drive system, each compressor pump is automatically staged on/off individually based on actual system demand, maximizing energy efficiency at all usage levels. Lead compressor status will alternate every time a pump is called for

– or every 10 minutes, whichever comes first – which maintains equal run hours and extends maintenance intervals.

WhisperAIR™ SOUND ENCLOSURE CABINET

Powerex’s trademarked oil-free enclosure systems offer the lowest noise levels in the industry. Each system is packaged in a rigid steel frame with powder coated panels and lined with sound-deadening insulation.

The low noise levels are unmatched in the industry and allow installation at the point of use, while the small footprint simultaneously maximizes floor space.

The scroll pump has few moving parts making it reliable and easier to maintain. The self lubricating tip seals and absence of a gearbox means the pump is truly 100% oil free. As the leaders in scroll pump technology, our latest design incorporates several innovative features:

• Main bearings are housed in durable cast iron instead of aluminum which prevents fretting and premature failure of the bearing race. This pump can be operated at 100% duty with confidence.

• The patented bearing re-grease feature has been improved to allow maintenance from the front side of the pump, cutting service time in half.

• The patented tip seal design yields the highest flow rates and longevity of any other dry scroll compressor.

• The improved efficiency and cooling results in lower operating temperatures.

• Extremely low vibration.

• Industry first 10hp scroll pump improves system efficiency by producing more output using fewer pumps.

B system performance www.n-psi.com

These advanced dryers use the pressure swing adsorption principle to efficiently dry compressed air. They use a heatless twin tower configuration (see diagram opposite) housed in a modular design. Each column contains a unique (and patented) desiccant cartridge which incorporates an inlet separator (D1 only) and outlet filtration.

Wet air from the compressor aftercooler enters the dryer and is directed into column A.

D1 only: Bulk liquids (water) and particles are removed by the separator on the inlet of the cartridge. Water is retained within the dryer until the column is regenerated, when it will be vented to atmosphere as it is depressurized.

D1 & D2: Air passes through the desiccant bed where moisture vapor is adsorbed. Then the dry air passes through a particle filter which retains any desiccant particles (< 1 micron / ISO8573.1 class 2 for dust).

Simultaneously, a small amount of dry air is counter-flowed down through cartridge B and exhausted to atmosphere, removing the moisture and regenerating the desiccant.

The dryer is controlled by a PLC which periodically switches the solenoid valves, reversing the function of each column and therefore ensuring the continuous supply of dry air.
