> HIGH PERFORMANCE ROTOR PROFILE

Particular stainless steel, which is superior in corrosion

resistance and durability is applied for rotor with highly

accurate grinding. Furthermore, to reduce internal

leakage, mirror finished surface enables to keep

appropriate clearance, including thermal expansion

during operation.

Hi-precooler system cools down high temperature

discharge air down to 180˚C and below before entering

aftercooler. This enables aftercooler to be less than the

upper temperature limit. EAGLE H applied this system

to large size, air-cooled model and improved reliability.

The rotor enlarges significantly due to thermal expansion.

Heat expansion of the rotor occurs since it exposes 300˚C

discharge air to the single-stage model. (200˚C even for

the two-stage model) EAGLE H original 3D correction

technology is used to keep the most appropriate clearance.

Maximum pressure changes from 8.8 bar to 9.3 bar

A variation of series composition due to high discharge

pressure makes possible of various system design of

variety.

Responding to the load rate of compressor, unnecessary

compression is avoided by automatically lowering the

unload start-up pressure. Energy-Saving is achieved.

Taking 75kW water-cooled, 7 bar SPEC, Fixed Speed

model as an example, in case of 70 % load rate 11.3MWh

is saved annually, and in case of 90 % load rate 28MWh is

saved annually.

(Calculation condition: air receiver tank of 2.26 m3 is installed, 8,000h /

year operation)

For VS-TYPE model, variable speed drive and air capacity

control are all originally designed by HERTZ. Control

system which enables to control the discharge pressure

within ±0.1 bar, not only makes high response to the load

possible, but also achieve great effect of Energy-Saving

together with outstanding stability.

> POWER REDUCTION AND RELIABILITY IMPROVEMENT DURING UNLOAD OPERATION DUE TO HERTZ ORIGINAL

UNLOADER-LESS AND INTER-STAGE PURGE TECHNOLOGY

> COOLING FAN (45 / 55 / 75 KW AIR COOLED MODELS)

Significant power reduction and reliability improvement of shaft seal during unload operation are secured due to Hertz

original technology of purging on both inter-stage and 2nd stage. And, because of unloader-less structure, maintenance

of unloader (suction throttle valve) is unnecessary.

Newly developed turbo fan is controlled by inverter.

Responding to the air delivery change, the rotation speed

of cooling fan is automatically lowered to achieve Energy-

Saving. At the same time, noise from cooling fan is lowered

too.

Continuous operation under up to 45˚C and long maintenance cycle are possible by adoption of new internal structure

which minimizes the internal temperature rise.

Oil Mist Remover (OMR), which recaptures the oil mist from gear case and recycle, is standard equipment.

Also, auto drain valves for inter-cooler and after-cooler are standard equipments to drain intermittently without air loss.

Reliability is improved due to the adoption of totally enclosed flange motor. Maintenance also becomes easier due to the

removal of coupling.

Large LCD display monitor is equipped as standard. Various functions can be easily set by control panel. In case of

trouble, the information of status of compressor is displayed so that it is possible to quickly carry out the Troubleshooting.

1. When the operation pressure is reduced from 6.9 bar to 5.9 bar, the maximum power consumption is automatically reduced to about 92 % of 6.9 bar.

2. When the pressure is reduced to 3.9 bar, the power consumption reaches about 79 %. If you know your air consumption for sure and wish to reduce the power consumption depressurization, PQ WIDEMODE OFF is recommended.

1. Reducing the operating pressure from 6.9 bar to 3.9 bar, the power consumption is decreased about 79 % of 6.9 bar.

2. With the excess power from depressurization, you can increase the air flow to 128 % of the rating. At that time, the power consumption reaches 100 %. If you wish to use maximum performance PQ WIDEMODE ON is recommended.
