Rotary Screw Air Compressor Permanent Magnet Variable Frequency
High Energy Efficiency 8bar
Why choose LTC Compressor variable speed screw compressor ?
1.High efficiency permanent magnet synchronous rare earth motor:
Compared with ordinary asynchronous motor, the efficiency of
high-efficiency permanent magnet synchronous motor (EPM) is
increased by 7%. Especially, it can maintain strong torque output
at low speed.
2.Stable, non-impact: Permanent magnet motor uses PID regulation to
start smoothly and softly. The motor current will not exceed the
rated current when starting, and will not impact the power grid and
the mechanical wear of the engine, which greatly reduces the power
failure and prolongs the service life of the main screw engine.
3.Wider working frequency range and lower noise: Frequency
conversion range from 5% to 100%. The greater fluctuation of user
gas consumption, the more obvious energy-saving effect, and lower
operating noise at low frequency are applicable to any place.
4.Industrial 4.0 Intelligent Remote Monitoring System: The remote
visual function can be realized through mobile APP. and the
real-time operation of air compressor can be seen at a glance even
thousands of miles away.

Advantages of permanent magnet variable frequency air compressor:
1. It has high energy efficiency and is equipped with a permanent
magnet motor.
2. Integrated design, high transmission efficiency, coaxial
connection between machine head and motor.
3. The permanent magnet motor combined with the vector frequency
conversion technology can maintain high energy efficiency even at
low speed. (When the gas demand is low, the power consumption will
decrease year by year, and the permanent magnet motor will keep
running at low speed)
4. The variable frequency startup of the permanent magnet variable
frequency screw machine has little impact on the power grid of the
entire factory.
5. Coaxial design of permanent magnet frequency conversion screw
machine, ultra-quiet operation.
6. Constant voltage output, vector frequency conversion technology,
saving energy loss caused by pressure loss.
