Kobelco Screw Compressors
Slide 1, and slide 2 shows the typical construction of Kobelco oil-free and oil-injected screw compressors in process gas applications.
Slide 3. shows the built-in slide valve, which automatically increases and decreases the actual suction volume. Brake horsepower therefore increases and decreases according to capacity, resulting in improved energy efficiency. The Oil-Injected Screw Compressor has a unique feature of tremendous power savings in cases of (a) turn down operation and/or (b) suction gas pressure fluctuation.
