Why KOBELCO?

Oil-free
Worry-free


What's most essential value for oil-free compres sors is to supply pure, clean, oil-free air stably in any running conditions. For critical applications, such as, food and beverages processing, semicon ductor and electronics manufacturing, medicines manufacturing and more, even the smallest oil contamination never been accepted.

As a pioneer of oil-free technology with over 60 years of history, Emeraude ALE/ FE series assure safe oil-free compressed air and utmost reliability for your production.

Class O Certified


KOBELCO has received Class 0 certification ( 1S08573-1 [-:-:0]) for (Emeraude ALE) series from international test institute called TOV which certifies the highest level of purity for qualityclassificationsof compressed air. This is one proof of KOBELCO's supreme oil-free technology.

CLASS Concentrated total oil(aerosol, liquid,vapor) mg/m³
0 As specified by equipment user or suplier and more stringent than class 1
1 <=0.01
2 <=0.1
3 <=1
4 <=5


KOBELCO's unique design to ensure "Oil -free"


Dual vent holes design

(Common for ALEN/ ALE/ FE)

KOBELCO's proven dual vent holes design prevents oil entry in compressor chambers during long unload running


3 steps of reliable shaft seal structure during unloading


Evolution continues, New generation starts



Now, brand-new chapter in the over 60 years history of KOBELCO's oil-free technology has just started, New generation Emeraude ALE debut.
With ultimate specific power consumption, supreme silence and outstanding durability, Emeraude ALE reached new stage in the industry.
Proudly standing dark green elegance is the result of our never ending challenges for technology innovation and craftsmanship improvement over the long history.
Pursuing the perfection, making it a masterpiece.

Class-leading specific power consumption

New ALE's performance is evaluated by specific power consumption as per JIS B 8341:2008 ( 1801217 Edition3 equivalent). KOBELCO places an importance on not only shaft power but also compressor's total input power including energy loss in the compressor because electricity consumption for customers is not shaft power and rated motor power but compressor's total input power.

Compared with Previous ALE: 3% Performance improvement

Why "Specific power consumption"?


Specific power consumption is the new valuation standard based on compressor's total input power and discharge air volume. It shows the actual customer's energy use.



Previous valuation standard evaluated discharge air volume and shaft power separately. New valuation standard evaluate "specific power consumption" which shows energy consumption to create compressed air of 1m3/min in addition to discharge air volume. This means an actual compressor performance including fan motors and an oil pump.

KOBELCO has achieved class leading performance with specific power consumption because of newly designed rotors, reduction of energy loss and selection of high efficient components.

Newly designed high efficiency rotors



rotor
A new rotor profile has been designed using advanced analysis technology that KOBELCO has fostered in their long history since developing the first oil free screw compressor in Japan in 1956. KOBELCO has achieved class-leading specific energy consumption thanks to the new rotors which have been designed superior performance.
Improved Points
  • Optimization of the inter stage pressure
  • Optimization of rotor clearance
  • Improvement of shaft sealing structure

Package design for no wasted energy



Internal piping design, high efficiency motors and fans contribute to energy savings. Moreover, gas coolers' optimization decreases the discharge temperature and downsizes auxiliary equipment such as dryers. This leads energy saving of not only compressors but also clean air systems.
