KRSA LOW PRESSURE
Kaishan 2, 3 and 4 bar Low Pressure Screw Air Compressors are specifically designed for Textile, Cement, Glass, Flue-gas Desulfurization and Pneumatic Conveying application.
When a 7 bar standard air compressor is run for a plant air pressure requirement of 2 – 5 bar, it will lead to higher power consumption as compared to Kaishan low pressure compressors. Kaishan low pressure screw air compressors with their patented low compression ratio can deliver same output flow (cfm) with 20 – 50 % lower power consumption.
The capacity of a screw air compressor with 132 kW motor at 7 bar will be 850 cfm. Kaishan low pressure compressor with 132 kw motor at 3 bar will have a flow of 1547 cfm. This power saving enables you to recover your investment in less than a year.
We designed our single stage compressors to offer several long-term benefits, including:
Improved energy efficiency
Together, these features make our KRSA compressors one of the most cost-effective options in the market today. In addition to being suitably priced, they are also economical to run on an ongoing basis.
EFFICIENT SKY ROTOR PROFILE
SKY series rotors are highly efficient and its world renowned 5/6 profile have evolved from previous generations to meet today’s industry requirement. Energy & Cost efficiency with increased output is achieved through following:
Large rotor size
To increase the rotor throughput, our Air Compressors are built with 5/6 lobes with a larger rotor size than the traditional profile. Therefore, they deliver lower specific power (kw/cfm).
Lower inter-lobe leakage losses
Greater the number of lobes, smaller is the pressure difference between the two-neighbouring working chambers thereby reducing inter-lobe leakage losses. Hence leakage to delivery ratio decreases as the number of rotor lobes is increased.
Large wrap angle & discharge port
A greater number of lobes combined with a large wrap angle ensure multiple rotor contact. This reduces vibration & thus minimizes noise. Larger discharge ports decrease the discharge velocity and therefore reduce the discharge pressure losses thereby increasing the overall compressor efficiency.
