Steam Turbine Oil Conditioning & Water Removal Systems

Kaydon Filtration is now part of the Donaldson Facet brand.

Since 1943, Kaydon Filtration systems have been the industry leader in steam turbine oil conditioning, setting the benchmark for reliability and performance across mission-critical applications.
Our proven systems deliver exceptional oil cleanliness, extend turbine life, and minimize costly downtime—trusted worldwide for over eight decades to protect the most valuable turbine assets.

High-Efficiency Oil Conditioning for Reliable Turbine Performance

The most efficient conditioning system in the market for water removal, TURBO-TOC® removes 100% of damaging water from turbine oil and reduces Total Water Content to 100 ppm (0 ppm free, 0 ppm emulsified, 100 ppm dissolved).

TURBO-TOC® systems deliver 99% removal of free and emulsified water in a single pass, reducing total water content to below 100 ppm. Designed for continuous-duty operation, units provide variable flow rates—up to 125 gpm—enabling multiple reservoir turnovers per day depending on system size and oil temperature.

This high-frequency circulation supports rapid decontamination, especially after seal failures or water ingress events. TURBO-TOC® units consistently achieve ISO 15/13/11 cleanliness levels and restore turbine oil to “clear and bright” condition, minimizing the risk of varnish formation, bearing wear, and unplanned outages.


TURBO-TOC® continuously removes harmful contaminates, keeping your oil system flushed and increasing reliability.

When both water and particulate are brought down to acceptable levels, bearing failures are eliminated.

A continuous flow filtration system efficiently removes contamination, preventing forced outages.

Clean turbine oil increases turbine dependability and helps reduce repair costs directly associated with contaminated oil.


The TURBO-TOC® system stands out for both its exceptional performance and user-friendly design. Delivered as a pre-engineered, ready-to-use solution, it requires no customer adjustments—simply install and operate.

All KL10, KL30, KL60, and KL100 TURBO-TOC® units feature advanced control panels equipped with PLC controllers, allowing seamless integration with existing monitoring systems and enabling remote operation. Minimal training is needed, making operation intuitive and maintenance straightforward.

With its easy-to-use, low-maintenance design, the TURBO-TOC® system delivers more than just filtration—it ensures optimal oil cleanliness and reliable protection for your critical machinery.

TURBO-TOC® Series

Stationary Systems

The TURBO-TOC® KL Series is engineered for continuous, high-flow oil conditioning in large turbine lube oil reservoirs, supporting volumes up to 24,000 gallons. With multi-stage coalescing technology, particulate control, and water removal, KL systems are optimized for permanent installation in steam turbine-driven power facilities where uptime, oil cleanliness, and system reliability are critical.

Portable Carts

The TURBO-TOC® KLP Series provides the same fluid cleanliness performance as the KL line in a compact, mobile platform designed for systems up to 1,800 gallons. Ideal for service teams or facilities with multiple smaller reservoirs, KLP units deliver ISO-compliant particulate and water removal with field flexibility, making them a strategic solution for planned maintenance, commissioning, or rotating equipment support.
