Oil Dehydration/Purification

Remove Water | Improve Performance | Increase Longevity

If you are only going to read one web page, Please read this one.

Whether engine oil or hydraulic fluid, there is no contaminant or catalyst more complex or destructive than water in oil.

If you could get the water out of your Oil or Hydraulic Fluid, how much could you reduce downtime, maintenance, and equipment costs?

You can increase the longevity of your equipment and reduce the total operational cost (see the presentation near the bottom of this web page).

Water reduces the life of oil and damages bearings, causes corrosion, oxidation, additive depletion, viscosity, create acids, sludge and more resulting in shorter component life. Many failures blamed on lubricants are truly caused by acids which are able to form from moisture. Effective humidity and water dehydration control of oil allows you to plan maintenance activities around your operational requirements.

Have you seen or noticed any of the following symptoms? If yes, we should talk.

5 Problems.png
  • Rust & Corrosion
  • Water Etching
  • Erosion
  • Vaporous Cavitation (hydraulic pump cavitation
  • Hydrogen Embrittlement

These can all be the result of water in oil or hydraulic fluid. But now, there is something you can do about it, proactively with oil dehydration purification technology as part of your preventative maintenance. 

See for yourself...

  • Have you ever experienced rust or other problems inside equipment on parts that are in oil or hydraulic fluid?
  • When you get your oil analysis do you ever score high or a 10 on acid levels?
  • Do you believe in proactive preventative maintenance?
  • Do you think analysis on new and used oil is of benefit?
  • Would it surprise you to find out that new, fresh oil has water in it?
  • Have you found emulisified, dissolved and/or free water in lubricating fluids?
  • Would you agree that water in oil causes problems that increases maintenance or downtime and reduces longevity of equipment?

The Insidious Impact

Water passing between loading frictional surfaces can explode, causing metal fracture. Depending on the oil type and temperature, a bearing can lose 75 percent of its life due to water contamination before the oil becomes cloudy.

A hazy or milky appearance may indicate a water emulsion or other interferences such as air, dyes, oxide insolubles, soot and solid contaminants. While most people are aware that new oil is typically bright and golden in colour, it is important to realize that new oil isn’t necessarily clean. If oil analysis has confirmed water ingression, the water should be removed as soon as possible.

Water ingression is the second most destructive contaminant and can wreak havoc in your system. Emulsified water is defined as microscopic globules of water dispersed in a stable suspension in the oil. Although all states of water in oil can cause damage to the oil and machine, emulsified water is considered the most destructive.

How we can help: Our patented technology offers a two-stage active dehydration/purification process. We combine a micro glass filter element and an active moisture removal chamber. The result: water is removed, not absorbed in the filter. If you already have effective filtration, we can just get the water out with a dehydrator device. Removing water reduces harmful acid and sludge contamination/buildup.

It is great for hydraulic systems, engines, gearboxes, transformers, turbines, and generators etc. 

Protect your investment.

Case Study Summary of Features

Conserver™ filtration systems are scalable and adaptable to a wide variety of applications, including gasoline and diesel engines, reverse osmosis water purification units (ROWPU), large industrial turbines, industrial presses, transformers and bulk petroleum storage units.  

The systems extend the life of oil and lubricants, protect the environment and significantly cut the total cost of ownership through reduced engine and hydraulic system wear and improved fuel efficiency.

Sometimes the return on invest can be less than one or two years.

CONCLUSION:  Next Generation Conserver™ Oil Optimization Systems:
Next Generation’s Conserver™ bypass filtration systems clean and dry oil and hydraulic fluids at a   rated efficiency of 99.98%, far outperforming. similar products on the market. 


  • Works on all internal combustion engines
  • Major reduction of oil used & disposed of
  • No power draw on water cooled equipment
  • Return on investment in under one year
  • Extends time between fluid drainage/changes
  • Scalable and adaptable for many applications
  • Removes 99.98% of particulate contaminants
  • Removes water without need for filter change
  • Reduces engine/system wear by factor of four



Success Story: Extreme Trucking

The goal was to test the NGFS Oil Dehydrator in a tough, extreme very harsh operating environment in the transportation industry.

At first, two trucks were outfitted with the NextGen dehydrator unit to run on Alaska's North Slope Via the Dalton Highway. This is one of two roads in North America that crosses the Arctic Circle. The route covers more than 500 miles one way and road conditions are paved and unpaved, moreover the weather ranges from 24 degrees C. to -45 C. (+75 fahrenheit to -50f.

The agreement that the engine oil would not be changed unless the oil samples that were sent to the lab indicated a problem. Filters were to be changed at 50K mile intervals. 

One Freightliner FLD120 truck logged 522,000 miles and the other 581,000 miles. Rod and main bearings were inspected on both units at around 345,000 miles. Result: “found absolutely no indication of wear.”

After the positive results were found, eight more trucks were outfitted. 

On the trucks with the Detroit Diesel DD15 engines, they have logged a total of 2,423,000 miles (ranging from 120,000 to 386,000 miles) and one truck had an oil pump pick-up tube problem. As part of the warranty work requirement, the crank had to be removed and inspected. Result: “The dealer was unable to find any wear in the bearings and reinstalled them.”

Summary Results: 

  • 3,523,000           Total Miles
  • 118                     Oil changes NOT performed
  • $34,220 (US$)    SAVINGS (parts & labour)
  • Plus, reduced engine wear, maintenance cost and projected longer equipment life.

Success Story: Manufacturing Pulp/Paper Gearbox

The challenge that was presented to remove the moisture to an acceptable level on three systems at a major pulp and paper manufacturer plant in Florida. All three of the systems at the plant have a history of contamination from oil’s worst contaminant, water.

Three NextGen Conserver units that were selected are as follows:

  1. Large Gearbox: On a large gearbox that had major water contamination and was in an open area to the environment, a Next/Gen Conserver® Hl4 with logic controls was placed (affixed).

    The Hl4 was tested on one of the more challenging contaminated units in the area but successfully reduced the PPM of water in the oil in the reservoir to an acceptable level in a short period of time.
  2. Lime Kiln Gearbox: On a smaller lime kiln gearbox, whose oil reservoir was also contaminated with water and was also in an open area to the environment, a Conserver G9H, l3 with logic control, was installed.

    The Hl3 quickly performed to remove water and clean the oil in the reservoir to normal.
  3. Portable/Mobile Cart: The third use was for a portable cart. A Conserver Hl3 with logic controls and self-contained was set up to be used on a temporary basis to clean contaminated oil from gear boxes.

    This unit also operated as promised and reduced water contamination to an acceptable level.
