Sample calculation of energy saving:
For example a standard 55kW screw compressor delivers air at 70%
loading and operates 5800 hours per years. Taking electricity cost
of USD 0.15/kWH, the additional energy consumed as comparing with
VSD compressor will be:
A. Energy consumed during unload operation assuming unload shaft
power absorbed is 45% of full load amount: 30% unload times x loss
during unload time = (45% x 55kW) x 5800 hour/year x USD 0.15 = USD
6,460/year.
B. Energy consumed due to cut-in/cut-out pressure band of 2 bar.g
assuming this counts for 14% of full load amount: 70% loading time
x additional 2 bar.g of differential pressure loss = (14% x 55kW) x
5800 hour/year x USD 0.15 = USD 4,689/year.
Total energy saved by using VSD compressor will be = USD 6,460/year
+ USD 4,689/year = USD 11,149/year.
In a conclusion, a VSD compressor can save annually the electricity
cost of USD 11,149, 3 years can then save USD 11,149 x 3 = USD
33,447 which could be more than capital investment for purchasing
another VSD compressor.

Our Advantage:
Every permanent magnet variable-frequency air compressor produced
by Wan Beardsley through sophisticated air compressor vector
frequency control technology reaches national grade-2 energy-saving
effect, some products have grade-one energy efficiency.
Shanghai rotorcomp screw air compressor is featured by high
efficiency, low noise, small vibration, small volume, low expense,
convenient maintenance, beautiful appearance and so on,
Shanghai rotorcomp points of each installation with a variety of
sensors can be. the measurement of the running state and the all
Chinese display on the screen, simple operation, high reliability.
It has the function of self checking root, according to the user
demand volume, automatic adjustment of running state. the interests
of customers: monitoring and advanced
communication systems make the operation of the compressor is more
reliable, higher efficiency and lower maintenance costs, the
computer control system to make the machine unload loss minimum,
prolong the service life of the compressor.
Shanghai rotorcomp Air System can be installed where you need
compressed air. Its low noise operation and integrated air
treatment equipment eliminates the need for a separate compressor
room. All our compressors are tested and delivered ready for use.
