Various System Combinations with k u s

To respond to the change of air use, HlTACHl provides various system combinations with VSD for further Energy-Saving.

V-M Combination System Single-V System/Multi-V System If 2 or 3 compressors are necessary, HlTACHl V-M combination Besides V-M Combination System, Energy-Saving is also possible system is your excellent choice. There is great merit on HlTACHl with any combination such as Single-V multi-unit control system, V-M combination system which divides 1 compressor into 2. or Multi-V multi-unit control system etc.

PQ WIDE MODE (JP No. 35161 08 and others, Japan Regional Award)

PQ WlDE MODE, by automatically adjusting the maximum rotation speed of the compressor, enables to increase the discharge FAD in case that the pressure declines. Compared to conventional VSD, compressor is possible to operate at a wider range of pressure (P) and FAD (Q).

Energy-Saving I Constant Pressure Control (V type) ECOMODE (Fixed Speed Series)

Responding to the load ratio of compressor, unnecessary compression is avoided by automatically lowering the unload start-up pressure. Energy-Saving a achieved. Taking 75kW water-cooled, 0.7MPa SPEC, Fixed Speed model as an example, in case of 70% load ratio 11.3MWh is saved annually, and in case of 90% load ratio 28MWh is saved annually. (Calcuhtion condition: air r w e r tank of 2.26m3 is installed, 8,000h'year operation)

Since Constant Pressure Control allows h~ghly precise

pressure control within range of kO.01 MPa, supply of compressed air at necessary pressure is possible with high efficiency.
