If 2 or 3 compressors are necessary, Hitachi’s V-M Combination System is your best choice - dividing 1 compressor into 2.
By automatically adjusting the maximum rotation speed of the compressor, PQ WIDE MODE enables an increase in the Discharge Air Capacity when the pressure drops. Compared to conventional VSD, NEXT Generation VPlus Compressors operate at a wider range of Pressure (P) and Air Capacity (Q).
