22KW 35-50% Energy-saving variable speed screw Compressor in TUV certificates 5 years warranty
Control Panel: Intelligent microcomputer-based control technology
can monitor and control in all aspects the complete machine
following your instructions.Remote control realizes unattended
operation.
Oil filter: Rotary filters are applied to completely remove the
impurities in the lubricating oil,easy to replace and free of oil
impregnate.
Cooler: It is designed for low temperature difference to increase
heat exchang area,and ideal to be applied to high-temperature and
high-humidity operating environment.
Motor: First-class motors are adopted,with the level of protection
being lp55 and insulation level being F.
Acoustic enclosure: It is designed into fully-closed mute box,in
which soundabsorbing sponge are attached for effective absorption
of noise,thereby making the noise 3-5dB(A)lower than that made by
the compressors of the same kind. It is reasonably structured
overall and very easy to maintain and repair.
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.
>Smooth starts and stops within seconds
>Continuous volume flow regulation from 25-100%
>Adjustable-speed drive from 15-60hz
>minimization of wear and maintenance costs
>No power-peaks during start-up
> nearly no idling
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.
