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. With frequency conversion soft start reduce in-rush starting current, reduce wear on electrical switch gears and motor windings.
Also maintain less power during starting and stopping of motors and increase protection to motors. Also reduce peak demand and improve power factor.
