Kaishan, a leading worldwide manufacturer of industrial air compressors, has introduced a new, advanced tech, series of industrial, low-pressure rotary screw air compressors. The new Kaishan KRSA low-pressure rotary screw air compressors are fully packaged and ready to be plugged into any system or operate independently. These compressor packages are equipped with Kaishan’s patented “SKYv” airend, enabling them to perform exceptionally well in a wide range of applications with varying demands and requirements for flexibility. With this feature, the compressors can effectively handle applications ranging from 25 psig to 45 psig, all within a single package ready to be plugged into any system or operate independently.
Kaishan 3 bar, low pressure rotary screw air compressors are specifically designed for low pressure applications such as textile, cement, glass, flue gas, desulfurisation and pneumatic conveyance applications. The KRSA series boasts a versatile lineup, offering power capacities ranging from 22kW to 160kW. They can also deliver pressure between 2bar and 5bar.g, all within a single, compact package.
With advanced variable discharge port technology, it offers a new level of efficiency and versatility, delivering the right amount of air pressure exactly when it’s needed. This ensures that the compressor always operates at its most efficient point, minimising energy consumption and costs.
Compared to conventional blower solutions within this pressure range, the KRSA offers several unique benefits. In addition to its innovative SKYv airend, a robust premium bearing design and variable discharge port results in improved efficiency, consistent airflow, reduced noise levels, a smaller footprint and a lower total cost of ownership throughout its lifespan.
When a 7 bar standard air compressor is run for a 2-5 bar pressure requirement it uses far more power than a Kaishan KRSA low pressure unit. With its patented low compression ratio, the Kaishan KRSA series can achieve the same output flow (cfm) while using between 20-50% less power. The capacity of a rotary screw air compressor with a 132kW motor at 7 bar will be 24m3/min. A Kaishan low pressure compressor with a 132kW motor at 3 bar achieves a flow rate of 43m3/min.
KRSA series up to 250kW are also available with Permanent Magnet Variable frequency (PMV) drive option for best in class part load efficiency,
