ksrp 2-Stage

Rotary Screw Industrial Air Compressor

75 – 400kW

This latest generation of energy efficient 2-Stage air compressors can reduce your energy expenses by up to  50%.

Kaishan’s ground-breaking world class range of krsp series 2-Stage rotary screw air compressors offers outstanding energy savings when compared to conventional single-stage compressors. They offer unmatched performance, efficiency and reliability for any compressed air reliant industry.

What is 2-Stage Compressed Air Technology?

Unlike a conventional single stage compressor, a 2-stage air compressor divides the overall compression ratio between two distinct rotary screw airends. This has the effect of significantly reducing internal leakage losses resulting in substantial efficiency gains as well as extending bearing life due to reduced applied loads.

Kaishan 2-stage air compressors require a smaller drive motor to produce the equivalent volume flow rate to that of a comparable single stage compressor.

Why is it much more efficient?

Remarkable efficiency savings are achieved through reduced internal leakage losses across each stage, optimised cool oil injection intercooling and enhanced airend geometry.

What are the investment benefits?

Replacing a single stage with Kaishan 2-stage air compressor technology will typically result in a very rapid investment payback based on energy cost savings. As energy costs continue to rise, these savings will increase. A conservative 17.5% power saving based on replacing a conventional 160kW compressor with a 2-stage unit could realise annual energy savings well in excess of $40,000 based on 8760 operating hours and $0.20/kWhr.

We  also offer high pressure krsp 2-stage compressors capable of pressures up to 40bar for PET bottle blowing applications.

pmv Rotary Screw

Permanent Magnet Variable Frequency

Air Compressor 15 – 250kW

Kaishan ingenuity has resulted in the global release of these revolutionary new rotary screw air compressors that bring together an integrated systematic optimisation  of an advanced permanent-magnet motor combined with a variable speed drive and Kaishan single and 2-Stage rotary screw technology to achieve outstanding energy efficiency.

This unique, integrated technology offers unsurpassed efficiency in industrial air compressors from 15 to 400kW. The range of Kaishan PMV compressors can be ideally matched to the needs of virtually any industry application.

Energy costs contribute 85% of the cost of owning a screw compressor over its lifetime, therefore selecting the highest efficient compressor will have a significant impact on your businesses bottom line. The PMV Series offer world class efficiency performance yet are heavy duty to ensure superior reliability and reduced maintenance costs.

The superior efficiency of our newly developed two-stage screw airend units is the fundamental reason for our Permanent Magnet Variable Frequency air compressor’s class leading performance.

Rare earth material technology gives the permanent-magnet synchronised motors higher possible rotating speeds, wider operating parameters and increased energy efficiency. Within their wide operating speed range the Permanent Magnet Variable Frequency rotary screw air compressors are able to maintain extremely high motor efficiency compared with those using conventional drive motors.

Once a mains frequency screw air compressor deviates from its designated working specifications, its efficiency drops. Kaishan’s Permanent Magnet Variable Frequency technology is able to adjust the motor’s rotating speed according to constantly varying demand.

 

By regulating the volume of air output, the compressor is able to maintain maximum efficiency within a wide turndown range. These machines are particularly suited to applications with widely fluctuating compressed air demand. Kaishan’s Permanent Magnet Variable Frequency air compressors offer remarkable energy savings.

  • Complete control of air output to match widely varying system compressed air demand.
  • Lower energy input for required air output.
  • Excessive part load energy consumption is significantly reduced as output matches demand.
  • Gradual increase in motor speed eliminates starting spikes and cost penalties.
  • A steady system pressure is maintained, lowering system stress and overall air demand.
  • Reduced artificial demand due to lower operating pressures.
  • Reduced maintenance time and expense.
  • Significantly lower noise levels.

Custom Designed Air Compressors

Our local and international design and engineering teams can work with you to build a customised air compressor to work in a variety of applications and environments.
Examples of this include stainless steel cabinets for operations in an extreme marine environment or skid mounted and heavy framed unit for moving around a mine site. If you have a special requirement, we can help. 

Variable Speed Drive

VSD is optional with our entire krsp range of single and 2-stage air compressors.
With the elimination of wasted energy, additional cost savings as high as 50% are possible.
In many instances savings mean the additional capital cost of the variable speed drive option can be recovered in less than one years operation.
