    Mr.Kerry Robinson from Australia
    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.

    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.

Shanghai rotorcomp Variable speed drive Screw Air Compressor adapting the amount of free air delivered to compressed air demand is the most economical operating method where demand for compressed air fluctuates considerably or where the stored volume is very small or where operating below peak load.

Reduce Energy Consumption

The costs of power consumption account for 70% or more of all costs during the operation. The electric charges of running air compressor account for more than 40% of all the electric charges in the factory.

The requirement of compressed air fluctuates violently in different time every day, different weeks, or different months every year. The range of fluctuation is 40% to 80%, Rotorcomp adjustable-speed drive screw compressor can meet the user’s requirement exactly. When the user needs less air delivery, Variable frequency inverter can reduce the capacity and reduce the power consumption at the same

To save the money


When buying air compressors, the traditional cost (ie, cost of purchase + maintenance costs), the proportion of only 25% of the total cost, while the energy consumption accounted for 75%.

Ordinary (frequency) air compressor than ordinary (power frequency) air compressor energy saving 22-30%;

Austrian Rendezvous permanent magnet variable frequency air compressor than ordinary (power frequency) air compressor energy saving 33-40%.

1. A 75KW ordinary air compressor, running 8000 hours a year, electricity 0.62 yuan / kWh, a year of electricity for the 75KW × 8000h × 0.62 yuan / (kw × h) = 372,000 yuan

Shanghai rotorcomp permanent magnet VSD 75KW air compressor, a year can save 35% of the electricity, a total of 372,000 yuan × 35% = 130,200 yuan;
