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,

tThe product uses intelligent module control system and favorable human-machine interface to realize fault self diagnosis, servo-type gas flow automatic adjustment and 24-hour unattended operation, and it belongs to one of the most advanced machine type both home and abroad.

At present, Our PM VSD screw air compressors include: integrated permanent magnet variable-frequency series, non-inductive permanent magnet variable-frequency series, s

ervo permanent magnet variable-frequency series

, low-pressure permanent magnet variable-frequency series,

two-stage compression permanent magnet variable-frequency series,

oil cooling permanent magnet variable-frequency series of screw air compressors,

refrigerated dryer series, adsorption dryer series, combined dryer series, high-efficiency precision dryer, gasholder, etc.

Products are extensively applied to industries like machinery, furniture, textile, chemical fiber, medicine, food, metallurgy, electronics, war industry, environmental protection, etc

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. The integrated options will reduce installation costs and pressure drops significantly, thus saving additional energy cost.

Shanghai rotorcomp compressors have integrated dryer, filters and oil-water separator available to protect your compressed air network. This quality air expands the life of equipment, increasing efficiency and ensuring quality in your final product.

Our Company

Shanghai Rotorcomp Screw Compressor Co., Ltd  founded in 1999, our company was a manufacturer of piston air compressors from 1985-1999. After 2000 our company headquarters moved to the international metropolis Shanghai and focused on screw air compressors, pressure vessel, refrigeration dryer, adsorption dryer and air filters with the support of Rotorcomp Verdichter Gmbh in German.

Shanghai Rotorcomp Screw Compressor Co. Ltd., Shanghai Ziqi Container Co.Ltd. have been cooperated with 2010 Beijing Nankou Railway Transit Machinery Co. Ltd., which belongs to China CNR Corporation Limited, as the strategic cooperation partner.

The Beijing Nankou company has processing equipment more than 100 sets, including large-scale precision equipment 90 sets and imported equipment 70 sets. Such as Hardinge double-ended grinder, Toshiba horizontal machining center, BW CNC vertical and horizontal machining center, Holroyd rotor profile grinder and Zeiss 3D measuring machine.

From 2017, we successfully develop the new generation oil-free air compressors with the ISO9001 certificate, ISO14001 certificate, energy-saving product certificate, OSHAS (Occupation Safety and Health management System) certificate, vonTUV certificate and CE Certificate.
