Lube Oil Coalescer Systems

lube oil coalescer systems

The harmful effects of moisture and particulate contamination in turbine lube oil have been well documented. Oil Filtration Systems® has combined the latest innovations in coalescer technology and pleated microglass filter media in one system to achieve optimal fluid cleanliness in steam and gas turbines.

Utilizing high efficiency coalescer/separator filter elements, these systems are designed to quickly remove large amounts of free water from turbine lube oil, achieving overall water content as low as 150 PPM. At the same time, the high efficiency pleated microglass filter elements are capable of achieving very low particle counts to as low as an ISO 15/13/10 Cleanliness Level.

Coalescing technology enables you to remove bulk free water at extremely fast rates – previously this could only be done by centrifuges. Coalescing technology outperforms centrifuges, is simpler to use, costs less to maintain, and is lower in initial purchase price.
