Advantages of 90KW Tankless Rotary Screw Air Compressor
As mentioned earlier, our 500 cfm air compressor has many benefits. Next, we present them individually.
(1) Efficient and cost-saving
Different air compressor types, different cost components. The machine cost of a typical fixed speed air compressor is almost 8% of the total cost. The energy cost is almost up to 85%. The machine cost of an VSD air compressor is slightly higher (about 10%). But its energy costs are much less. It is only about 50%.
Ordinary 500 cfm power frequency air compressors always frequently load between 6~8bar. In fact, only 6bar is used. Then, the extra 2bar climbs frequently. This will make the air compressor consume 14% more. So for every 1bar climb, almost consume 7% more current. Assume that the actual accumulation of frequent climbs is 70%. Take 90KW 500 cfm air compressor as an example. It runs 8000 hours per year. The electricity fee is calculated at 0.7CNY/kWh.
Electricity wasted by frequent climbing:
70% loading time*(90KW*14%)*8000 hours*0.7≈49,392CNY/year.
(If it is a 500 cfm variable frequency air compressor, it always supplies air at a stable pressure. So there is no loss in this part.)
The unused part wastes electricity bills:
30% unloading time* (loss 90KW*40% no-load loss)*8000 hours*0.7≈60,480CNY/year.
Three-year power saving of 90KW 120 HP air compressor far exceeds the purchase cost of the machine:
(49392+60480-inverter power consumption 3%*90KW*8000 hours*0.7) *3 years ≈ 284,256CNY.
