Product Description

8 Bar 100 HP Variable Speed Inverter Air Screw Compressor

An air compressor with Variable Speed Drive (VSD) automatically adjusts the compressor's operating speed to match production of compressed air to demand in real time. VSD compressors are designed for operations where demand for compressed air fluctuates, such as facilities that operate different processes or multiple shifts so flow demand increases and decreases throughout the day.
 

Compared to fixed speed compressors that operate only at full speed, VSD compressors offers several benefits:
Because the VSD compressor only runs when needed, it reduces energy cost-typically enough to pay for the additional investment in VSD technology.
* A VSD compressor can start/stop under full system pressure. There is no need to unload, which saves both time and energy. * No time is lost to idling.
* No blow-off losses occur in normal operations.
* Power company penalties for peak current at startup are avoided.
* Air system pressure is more consistent and also lower, minimizing leakage

Energy savings
The largest component (about 70%) in the total cost of ownership for an industrial air compressor is not the equipment itself. It is electricity. A VSD compressor costs more to purchase than an otherwise identical fixed speed compressor, but the extra initial investment is typically returned through energy savings. VSD technology can reduce energy cost for a compressor by 35% to 50%, depending on the application and the size of the compressor, so annual savings with VSD can range from hundreds of dollars to tens of thousands of dollars.

Variable frequency screw air compressor:
1. Constant pressure control: It can realize high-precision constant pressure control with a pressure fluctuation range of 0.01 MPa;
2. Variable frequency soft start: Eliminate the peak current when starting, avoid grid impact, avoid current impact through step-by-step speed adjustment, and improve flexibility
3. Prevent no-load: The compressor is no-load during operation, reducing ineffective energy consumption;
Permanent magnet motors use high-efficiency rare earth magnets, no loss of magnetism at 180°C, and long service life; energy saving is about 6% to 7% compared with ordinary frequency conversion motors;
It can exert the highest efficiency in a wider range and make the air compressor more energy-saving.
