Matches compressor output with demand by varying motor speed. The power
consumption reduces in line with the reduction in demand. Helps in eliminating the
frequent load-unload cycle & also the wasted power from the energy bill.
A fixed speed compressor operates on a load unload band of at least 10 psi around
the working pressure whereas with TEKFEN COMPRESSOR VFD, compressor can be
operated within a band of 2 psi.
Since the compressor is not operated under higher than working pressure
requirements, there is substantial energy saving. For every 2 psi reduction in
operating pressure. there is 1% power saving.
In a fixed speed compressor with Star-Delta starter, starting current is as high as
three times the full load current (FLC). With TEKFEN COMPRESSOR VFD, starting
current is less than FLC. This helps to avoid using heavy rated components like
fuses, MCCB, cable size, generator rating, isolate etc.
