Ultimate Energy Efficient KOBELCO's Flagship
By developing state-of-the-art air-ends and optimized package design, we achieved best in class specific power consumption as well as utmost durability. Here, new standard of oil-free compressors starts.
Range
With specific power consumption as our primary design criterion, we strive to deliver products that maximize energy efficiency for our customers. The integration of ultra-high-efficiency motors and optimized package design has enabled us to set a new benchmark for specific energy performance in its class.
KOBELCO’s proven dual vent holes design prevents oil entry in compressor chambers during unload running.
KOBELCO has received Class 0 certification (ISO8573-1 [-:-:0]) for〈Emeraude ALE〉series from international test institute called TÜV which certifies the highest level of purity for quality classifications of compressed air.
Long Overhaul cycle has been achieved thanks to long life cycle bearings.
Various noise control techniques has drastically reduced sound level. Making the working environment more comfortable.
Proven Teflon coating and 2nd stage’s Stainless steel rotors secure high durability against drain attack and prevent performance deterioration due to corrosion.
Cooling air inlet points have been put into one place to reduce noise.
Noise absorbing material and high sealing ability against abrasive noise reduce noise leakage.
Newly designed suction and discharge silencers reduce noise level.
Easy access to key service parts for maintenance thanks to large panels and reduction of internal piping.
Filter type and compact exhaust cleaner has over 99% of oil mist separation performance and keeps inside of unit clean. Moreover, pressure resistance doesn’t increase for long time because oil mist is separated itself.
Heat loss is small and high efficiency is kept even during low load condition.
Equipped with a 7-inch full-color touch screen controller, it allows for easy monitoring of compressor operation and various settings.
By interconnecting multiple units, max, 6 units can be automatically operated, achieving optimal energy-saving operation without group controller.
* Keep the water temperature below 40℃ for water cooled model.
* Please refer to standard specification manual for water quality.
*Please contact our sales team for more updated specification and information.

* Suction conditions Absolute suction pressure: 0.10MPa, Suction temperature: 20℃, Humidity: 0%RH.
* Discharge air volumes is converted to suction conditions.
* Discharge pressure are measured after gas coolers.
* Air produced by compressors should not be used in respiratory equipment furnishing air for direct inhalation.
* Nominal working pressure of 0.75MPa & 0.86MPa model is 0.70MPa.
* Nominal working pressure of 1.04MPa is 0.90MPa.
* Since the cooling for the compressed air & the inside of the compressor unit depends on the surrounding air condition, the surrounding air must be properly ventilated to prevent the ambient temperature from rising above 45℃. ( For air-cooled 1.04MPa model, the surrounding air temperature should not exceed 40℃ )
* Please be sure to use the lubricating oil recommended by KOBELCO.
* Specifications and appearances are subject to change without notice Contact us if guaranteed values of performance is needed.
