ROTARY SCREW COMPRESSORS

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.
