Specifically designed inverter couple with IPM motor can make a power-saving effect that no-conventional inverter can make.
Capability for high pressure applications
Air cooled unit (0.88 MPa), water cooled unit (0.93 MPa)
Line pressure control (Optional)
● Maintain a necessary pressure in the line
● The best energy saving operation is possible with an optimized discharging pressure
● Keep track of the pressure losses (losses in electric power consumption)
High performance screw unit
A completely new design of the two-stage compressor unit and a reduction in package internal pressure losses resulted in an energy saving by 8% over existing models.Furthermore, a plate-fin, the first in the industry, was incorporated for the water-cooled, inter cooler and after cooler, reducing the air pressure loss to 1/5.
Ultimate clean air
The oil-free design introduces absolutely no oil to the rotor chamber in the process. Stainless steel shaft-seal rings are used to prevent the generation of carbon dust, and KobelcoÕs patented twin atmospheric shaft vents prevent lubricating oil from contaminating the compression chamber even during extended periods of unloaded operations.
Improved maintainability
Capability with 1.03 MPa specifications
All models are equipped with a compressor main unit that can operate with a pressure of up to 1.03 MPa.
Improvement on durability for ambient
Alternate operation function of two units-Graph display of operating history, weekly timer, daily report management, maintenance information, and operation status.
Built-in Higher harmonic reactor as standard
Screw Compressor Used
* Complies with harmonic suppression guidelines by the Japan Electrical ManufacturerÕs Association (JEMA)
Soft start by KOBELCO inverter
Totally enclosed fan-cooled motors are adopted to increase motor durability.
Protection features
Various improved protection for Electric parts.
Momentary interruption protection: Within 0.5 sec.The compressor unit does not stop even when an momentary power failure (momentary power interruption, momentary power drop, temporary blackout) occurs, as long as the interruption time interval is less than the set value. The compressor unit is stopped when the power interruption duration exceeds the set value.
Built-in 12,000-V lightning surge killer and noise filter.
Automatic reset from power failure: 0.5 to 20 sec.
Example: Setting for recovery after power interruption: 5 sec.; power recovery standby time: 15 sec.
Vane Compressor
Exhaust cleaner that requires no oil mist breather piping
This Exhaust Cleaner has its self oil separation and recovery function. This can prevent differential pressure increase and can realize long term maintenance interval.
