MAGNETIC ENERGY screw compressors feature a Permanent Magnets motor:
The losses reduction produce an increase in the overall compression system efficiency, matched with a Variable Speed drive, results in the best possible performances in terms of energy consumptions and overall compressor life and reliability.
The purchasing cost of an air compressor represents on average a small percentage of the total cost of operating the compressor over its life time. The power required to the machine (kW/hr) is absolutely the highest cost during this time.
Compressed air is used in all industries, it can be very expensive if incorrectly operated. Measurements conducted on a typical application show how the air demand varies constantly during the daily or weekly cycles. A conventional on load/off load compressor uses large amounts of energy when not required compaired to a variable speed compressor fitted with permanent magnets motor.
The application of a frequency inverter offer many advantages:
PERMANENT MAGNET ENERGY variable speed average 40% saving, Variable speed standard motor average 30% saving, Standard control stop/start no energy saving. Taking into account the initial higher capital exposure on a permanent magnet variable speed compressor and the energy saving of up to 40% over standard control compressor, initial payback on capital could be made within a very short period given the correct selection of permanent magnet compressor.
