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.
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.
