The rotary screw air compressors offers a compact design, small footprint, and low operating noise. It can be installed wherever it is needed, even be placed in the production area.
With the VSD compressors, variable frequency speed control technology can stop and start the compressor, achieving 0- 100% stepless speed change. The compressor's displacement can be perfectly combined with the user's air requirement (the air discharge will change by the speed of the motor). Compared with common screw air compressors, it saves electricity by about 30%.
The cost of a compressor consists of three parts: initial purchasing costs, maintenance costs, and energy costs. Among them, energy costs account for approximately 80% of the compressor's cost, and maintenance and procurement costs account for 20%. With frequency conversion, energy costs are reduced by more than 30%. In addition, the impact on the compressor after frequency conversion start is reduced, repair and maintenance cost will also decrease, so the operating cost will be greatly reduced.
The cooler is specially designed for high temperature and high humidity areas. This not only increases the heat exchange capacity by more than 10%, but also strengthens the material structure.
Making use of smaller rotors and higher speeds will reduce manufacturing costs, however, we have found that the use of larger diameter rotors and lower speeds will achieve better energy efficiency and longer durability.
We use durable, larger bearings in order to meet the specifications of larger diameter air ends to achieve superior performance and a longer lifespan.
With variable speed control technology, the air demand perfectly synchronises with electricity consumption to avoid waste of loading and unloading control.
The variable frequency compressor, with speed changing control technology, perfectly meets customer requirements. When the air consumption is increased or reduced, the speed control technology controls the compressor's air volume demand automatically, and enables the compressor to reduce electricity consumption.
