Energy Efficiency

Hitachi Control Methodology

Hitachi Standard Microprocessor based variable frequency control keeps the pressure stable in a narrow operation band. This allows significant energy savings over conventional control methods.

Hitachi Innovative Design

(Patent USP 049521)
To build the World's First Oil-Free Single Stage Rotary Screw Compressor, it was nessary to optimize rotor clearances.Greater efficiency and high reliability are based on hitachi's proprietary rotor profile and coatings formation. This Innovative is also incorporated into the design of the HITACHI OIL Froo Two Stage.

Matched VFD & High Eficiency Motors

Precise selection and application of electrical components enables HITACHI Variable Speed Drive compressors to main high efficiency throughout the operational range.

Versatility of Design

PQ WIDE MODE (V-Plus)

(Patent Japan P3516108)
Free air delivery is increased by maximizing the power avalable.HITACHI is able to adjust the speed of the operation to provide greater air output with lower pressure settings. (PQ WIDE MODE is available for only limited models.)

Maintenance Friendly

HITACHI Oil Free rotary Screw Compressors are Constructed to enable easy accessibility for inspection and maintenance. Incorporation of leading technologies allows the final product to consume less spce, enabling more area for enduser accessibility.
