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.
