Long Life Cycle VSD Screw Compressor With Wear Free Rolling Profile

China Shanghai Rotorcomp Screw Compressor Co., Ltd certification
China Shanghai Rotorcomp Screw Compressor Co., Ltd certification
today I ran the compressor and I am very happy with the workmanship and the quality , it is connected to a nitrogen generator that requires around 0.8 MPA feed air from the 30 kw compressor we are commissioning it I have found that it loads and unloads from 25.5 kw - 30 kw this will be a huge saving on power consumption.

—— Mr.Kerry Robinson from Australia

We've been used Shanghai Rotorcomp compressors over 18 sets from 10hp to 160HP installed with Oxygen generator since 2008. Most of compressors still in good working conditions without much maintenance.

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.
