S2M Magnetic Bearings offer a reliable and oil-free solution for high-speed natural gas turboexpanders, enabling OEMs to offer units that are low in maintenance needs. This is vital for many countries, since the turboexpanders are mostly installed on remote natural gas treatment plants in the deserted locations where accessibility for maintenance is difficult and costly.
Advantages
• No mechanical contact– no wear
• No contamination to the process fluid with lube oil
• Powerful monitoring and diagnostic tool, monitoring shaft vibrations and temperatures with integrated sensors
• Operation in remote and harsh environments
• High rotational speeds (up to 17 000 r/min)
Features
• Two radial bearings (150mm) with built-in detectors and auxiliary (back-up) bearings plus one thrustbearing
• The bearings have a reinforced insulation to withstand the sour gas environment
