Product Description
Kobelco patented 46 lobe Lambda Profile Rotor and Casing with new FEM analysis enhances reliability of heart of compressor
Quality Efficiency and Reliability backed by nearly 100 year history of KOBELCO as compressor manufacturer
New developed screw profile is designed by finite element analysis It minimizes air leakage from discharge end to suction end due to noncontact rotation realizing high efficiency
Patented Super Rotor profile Generation2
Kobelco patented rotor profile Lambda is one of world best efficient rotor profile
This profile gives 34 higher efficiency than that of industrial standard
Rotor surface is coated with PTFE spray baking for anticorrosion
LP stage made in forged CS and HP stage made in forged Stainless for better corrosion resistance
Patented Energy Saving Logic
Energy Saving Logic is Kobelco patented technology of capacity control method
Our standard equipped ITCS controller calculate air consumption and reducing unload pressure maintaining minimum pressure as well as minimum loadunload interval
This control enables user to run at optimum loadunload setting without special equipment and expecting 23 energy saving from conventional control
Better unload characteristics
Compare to turbo compressor oil free screw compressor has better energy saving characteristics
ALE can use as capacity controller to match with plant work load
For example Tire company use turbo compressor as base load and ALE to cover partial load since ALE do not have surging problem
No Vbelt No Coupling design eliminate chance of misalignment frequent tension adjustment and minimize mechanical loss
Rigid construction with quality components realizes industrial lowest vibration characteristics
ISO 5 AGMA 12 high accuracy gears have advantages of long service life less transmission losses low noise and low vibrations
Resistance to Extreme Conditions
ALE series designed for continuous operation under 45degC ambient condition with 5degC tolerance as standard
Standalone oil pump enables prelube and afterlube to prevent DRY START
The oilfree design introduces absolutely no oil to the rotor chamber in the process
Stainless steel shaftseal rings are used to prevent the generation of carbon dust
Kobelcos patented twin atmospheric seal vents prevent lubricating oil from contaminating the compression chamber e
ISO85731 Class Zeroven during extended periods of unloaded operations
