55 KW Variable Speed 75 HP Rotary Screw Air Compressor

The main advantage of this 55KW screw air compressor is energy saving. Generally, it can save energy by 10%~35%. The amount of energy saving is mainly based on two factors. That is, the working conditions of the industrial air compressor and the parameters setting of the inverter. Of course, the biggest factor is the actual application condition of the screw compressor. When the factory air consumption changes greatly, the energy-saving effect will be better. The direct data is the ratio of the no-load time to the total working time.

So how much can a 55KW 75 hp PM VSD rotary screw air compressor save energy in a year?

Assume an average load factor of 70%. The industrial air compressor runs 8000 hours per year. The energy consumption of a 55kw fixed-speed air compressor is as follows:

① Loading power consumption:

70% loading time*8000 hours/year*55KW=30800 kWh/year

② Unloading electricity consumption (that is, no-load energy consumption):

30% unloading time * 8000 hours/year * 55KW * 45% (power consumption during unloading) = 59400 kWh/year

③ Power loss caused by control pressure:

That is, For every 1 bar increase in pressure, power consumption increases by 7%. Saving 2bar is equivalent to saving 14% of power consumption.
70% loading time*2bar differential loss 14%*55KW*8000 hours/year=43120 kWh/year

Electric energy saved by 75 hp VSD screw air compressor = unloading electricity consumption + power loss caused by control pressure = 59400 kWh/year + 43120 kWh/year = 102520 kWh/year

Assume that each kilowatt-hour of electricity is 1 CNY. Then the 55KW variable speed air compressor can save almost 102520CNY per year.

The structure of screw type air compressor itself is simple. Moreover, this 55KW screw air compressor uses high-quality parts. For example, the airend is the Hanbell brand. The frequency converter and controller are Inovance brands. The startup disk is from Schneider. So our 75 hp screw air compressor has a long service life.

In addition, it adopts an energy-saving control system. This air compressor uses a soft start. Electrical shocks to motors and electrical components are thus reduced. It extends the service life of the compressor motor. At the same time, it also reduces the mechanical impact on the equipment. Therefore, it extends the life of the airend bearing and the gearbox.

Because of the energy-saving controller, this 55 KW air compressor is often in a loaded state. Therefore, it reduces the action times of solenoid valves and pneumatic components. Their failure rate is greatly reduced.

Because we are screw compressor manufacturer, our price has advantages. Besides, we can customize it to your special needs. For example, we can print your logo on our industrial air compressor. And different colors are available. In addition, our factory can also customize the special voltages. 220V, 415V, 440V and 460V three phase or 60HZ are acceptable. More importantly, we can provide full technical support.
