Flow chart (FE series)
New screws
New developed screw profile is designed by finite element analysis It minimizes air leakage from discharge end to suction end due to non-contact rotation, realizing high efficiency.
Thermal expansion finite analysis
Direct drive transmission
There is a gearbox between airends and motor without coupling, in order to reduce mechanical losses. ISO 5/AGMA 12 high accuracy gears have advantages of long service life, less transmission losses, low noise and low vibrations, etc.
Supreme thermosetting coating
Screws’ surfaces and inner walls of airend housing are coated by PTFE or MoS2 thermosetting coating which has super strong adhesion, anti-corrosion and high thermostability properties
Two vent holes construction (Kobelco Patent)
Two vent holes construction ensures no oil entering compression chamber through the seals even if the compressor is unloading for a long time
Minimize pressure fluctuation
To reduce pressure fluctuation, Kobelco adopted pivotal unloading valve and achieved to reduce pressure fluctuation from 0.1MPa to 0.05MP which eliminates eliminating energy consumption caused by unnecessary pressure rise.
Energy Saving Logic (Kobelco Patent)
It can unload the compressor in advance if unload/load cycle is longer than setting time (at least 23s). Thus eliminate energy consumption caused by unnecessary pressure rise.
Coordination of two units
2 units can be coordinated running by simply wiring them. without group controller Its own controller can set start sequence.
Standard configured wiring terminals for connection with ordinary group centrollers.
