Keep Condensate Out Of Your Terry ZS4 Steam Turbine With Isomag Bearing Seals

Water contamination in bearing oil is a common recurring issue for steam turbines in the oil and gas industry. Labyrinth isolators fail to stop condensate from entering the bearing housing as steam dissipates from the carbon box. A Marathon refinery has hundreds of steam turbines in operation, and a common maintenance procedure is to drain the water out of the bearing housings.

Marathon refinery in Garyville, Louisiana put an end to this issue by replacing the existing labyrinth isolators with Isomag bearing seals. Since installed in 2015, the end user reports that the seals are running smoothly at low temperatures with no evidence of water contamination. The old practice of evaporating water out of the oil twice a year is no longer necessary.
