The Ex-Dri Water Removal Purifier is an advanced oil purification system specifically designed to eliminate multiple forms of oil contamination, including free, emulsified, and dissolved water, as well as solid particles, sludge, varnish, and even acidic by-products. Unlike conventional vacuum dehydrators, the Ex-Dri adopts a unique drying method that removes water without degrading the oil or stripping additives. This makes it particularly suitable for high-viscosity oils up to 460 cSt, which are often difficult to treat with traditional purification technologies. Recognized by the Korean Government as an “Excellent R&D Innovation Product,” the Ex-Dri provides industries with a robust, efficient, and durable solution to maintain oil cleanliness, extend lubricant service life, and prevent costly equipment failures.

Capable of removing all three forms of water (free, emulsified, dissolved) with high efficiency.
Designed for high-viscosity oils, making it applicable to challenging lubrication environments.
Prevents loss of oil additives and ensures no thermal degradation of oils during purification.
Simultaneously removes solid particles, sludge, varnish, and acidic contaminants.
CO type models specialize in rapid removal of large volumes of free water.
VR type models are tailored for varnish and acid removal.
Optional digital display provides real-time monitoring of temperature, humidity, pressure, and differential pressure.
Proven field applications in turbines, compressors, hydraulic systems, and large-capacity oil tanks.

Moisture is one of the most harmful forms of contamination in lubricating oils. When present, it accelerates corrosion, depletes the lubricating film, and causes direct metal-to-metal contact, which leads to abnormal wear and premature equipment failure. The Ex-Dri system not only removes this moisture but also prevents further degradation by eliminating varnish and sludge that clog valves and reduce turbine efficiency. By applying Ex-Dri, operators can:
Extend equipment service life and improve reliability of turbines, compressors, and hydraulic systems.
Maintain lubricant performance and reduce the frequency of costly oil changes.
Minimize unplanned downtime and lower overall maintenance costs.
Ensure operational stability in high-demand industries such as power generation, petrochemicals, paper, steel, and cement plants.

1. Connect the Ex-Dri purifier to the oil reservoir or circulation loop using the inlet and outlet ports.
2. Power on the system and select the appropriate operating mode (standard, CO type, or VR type depending on oil condition).
3. Allow the oil to circulate through the purifier. The disc module and filtration units remove particles, water, and sludge simultaneously.
4. Monitor the purification process via the digital display (optional) for parameters such as temperature, humidity, and differential pressure.
5. Continue operation until desired oil cleanliness and water content reduction levels are achieved (field cases demonstrate reduction from over 8,000 ppm to less than 50 ppm within 48 hours).
6. Shut down the system and perform periodic maintenance, including filter replacement and inspection of the disc module.
