37Kw/50HP variable frequency oil injected screw air compressor

37Kw/50HP Variable Frequency Injected Screw Air Compressor  

   Product Description DENAIR Variable Frequency Air Compressor   Standard Variable Frequency Oil Injected Screw Air Compressor Performance Advantages: 1. The value of the variable frequency compressor Energy Saving:33% Power Consumption    2. Advantages of Starting Variable Frequency soft start, smooth linear operation, no traditional direct start and Y- triangle starting peak current, effectively improve the motor and the electromagnetic contactor life, while avoiding the risk of being fined in line with electricity over power sector.   3. Low noise Source Of Compressor Noise
1. Air End Operation Noise
2. The fan operating noise
3. The main motor running noise
Improvement on the Machine by adopting Variable Frequency Type
1. As the operating frequency of Variable Frequency Type is less than Power Frequency Type,mechanical noise down and mechanical wear smaller.
2. If fan also adopting variable frequency driving,it can significantly reduce the noise while working   4. Variable flow rate control
1. Frequency-driven compressor only with one displacement,Variable Frequency Type with
displacements in a very large range. Frequency changer can control the displacement by adjusting the motor's speed based on the actual air consumption.
2. For Variable Frequency Type,compressor can be auto sleep condition while in less  consumption, which can greatly reduce the loss of energy.
3. Optimized control way,which can better improve the energy saving effect.
4. Why the air flow can be controlled by adjusting speed?
n=60f/p(1-s)
n: Motor speed f: Hertz p: Number of pole pairs of motor
s: Slip ratio of motor   5. Stabilivolt
1. Variable Frequency Type Air Compressors can be softly starting by taking advantages of
stepless governor features through the controller or PID adjuster inside of converter. For
the working site that require air consumption with big fluctuations,this type air compressor can
be quickly adjusting accordingly.
2. Comparing with power frequency type adopting Upper and lower control,the pressure stability
for Variable Frequency Type will be exponential increase.   6. Putting en end to the situation of using the high pressure on the low pressure application
1. Waste of High Pressure is very bad like too much for use.Normal Screw Air Compressor will be always loading and unloading in 6~8bars, but actually the working pressure is just 6bars, which means the extra more 2bars will let the air compressor cost more 14% energy(each single bar will cost more 7% current). Total extra more cost will be 70% based on the frequent loading time. For example, one unit of 37kw air compressor will more waste of 20,300 yuan per year because of this 70% frequent loading. But for the same machine,if it is variable type, it will keep 6bars working pressure to supply the air, which will result no more 2bars loading loss.
2. The loading wasting calculation way: 70% unloading time x(37kw x 14% which is because of the 2bars loading or unloading)x 8000hours/year x 0.7 yuan=20,300yuan/year.
