Effectively Eliminating Water Contamination from Hydraulic and Lubricating Fluids

EPT_WhitePaper-Water Removal.indd 1 2016-09-09 3:02 PM

Water is the most common and damaging contaminant found in hydraulic and lubricating systems. All mechanical systems have a certain tolerance for contamination, but in many cases these tolerances are lost due to ineffective maintenance. Therefore, eliminating this failure pathway by adding an effec-tive water removal program to your lubricant maintenance, is an essential step in achieving reliability targets.

From an equipment perspective, you can easily double the life of your mechanical systems by reducing water levels (Table 1). Doubling equipment life also increases the “trouble-free” operating window and reliability of equipment, and significantly decreases the risk of production losses.

WATER IS A PRIMARY CAUSE OF LUBRICANT FAILURELubricant breakdown is caused by oxidation and hydrolysis. Any ester-based lubricant is sensitive to hydrolysis, which is the breakdown of the original base stock through reaction with water. Water reverses the chemical process originally used to manufacture the ester, so managing water levels is a key component to the effective maintenance of these lubricants.

While mineral oils are not sensitive to hydrolysis in the same way as ester-based lubricants, water shortens lubricant life by promoting oxidation, acid formation, and may also remove additives. Aside from temperature, the rate of oxidation is based on the amount of water, oxygen, and metal catalysts that are present.

THE BASIS FOR EFFECTIVE WATER REMOVALFor proactive hydraulic and lubricating fluid maintenance, the program needs to move beyond reactionary measures and actually manage the drivers of oxidation where possible. In doing so, you can significantly reduce the amount of maintenance required and extend lubricant life.

Water can exist in 3 forms: free, dissolved and emulsified. Free water is the excess water above the fluid’s saturation point and is visible as a separate layer (Fig. 1). Dissolved water is below the fluid’s saturation point and is not visible. Emulsified water is the point in between free and dissolved where water first becomes visible as a “haze” (Fig. 2). The key point is that just because you cannot see water, does not mean it is not there.

Fig. 1—Free water can be seen forming in the bottom of the beaker as the dissolved water comes out of solution.

Fig. 2—Emulsified water can be seen throughout the sample with a small amount of free water observed in the bottom of the beaker.

“ Water can exist in 3 forms: free, dissolved and emulsified…just because you cannot see water, does not mean it is not there.”




The first water in lubricating fluid will always be in the dissolved form. The amount of water the fluid can hold in the dissolved form is a function of the type and temperature of the lubricant. As temperature increases, more water can be held in the dissolved form as the saturation point increases. The movement of water from one form to another is a physical change.

Understanding which form the water is in is critical when selecting which water removal system to use. Some water removal technologies only remove free water, so using these tools on systems with only dissolved water would be ineffective (Table 2).

Source: Machinery Lubrication

Another important consideration when selecting a water removal system is the water ingression rate and frequency. While these exact numbers may be difficult to pinpoint, what needs to be understood is whether there is a large water ingression problem or a small one, and whether it is happening frequently or infrequently. A large water ingression issue that is happening frequently may require a more robust solution versus what may be required for small, infrequent ingression (Table 3).

“ The first water in lubricating fluid will always be in the dissolved form. The amount of water the fluid can hold in the dissolved form is a function of the type and temperature of the lubricant.”




SOURCES OF WATER CONTAMINATIONUnderstanding the source of water contamination is equally important to understanding water ingression rates. Water is generally added to hydraulic and lubricating fluids from either a mechanical process or from the atmo-sphere. While it is desirable to fix all mechanical ingression points, atmo-spheric contamination is the most common water ingression pathway, but is often overlooked and treated as a fixed constraint that cannot be addressed.

While the use of desiccant breather elements to restrict moisture ingression is common, their usage only reduces relative humidity (RH%); it does not complete-ly dry the air and is insufficient to mitigate atmospheric water ingression. In high humidity environments, desiccant breather elements can be changed weekly and still not isolate the impact of atmospheric water ingression.

All lubricants will move towards equilibrium with the atmosphere contact-ing them. In most cases, where the moisture content of the atmosphere contacting the lubricant is higher than the moisture content of the lubricant, water will be transferred from the atmosphere into the lubricant. In this situation, the transfer of water from atmosphere to the lubricant occurs via mass transfer.

Fig. 3—In atmospheric breathing hydraulic and lubricating fluid reservoirs, the humid air above the lubricant will transfer water into the lubricant via condensation/mass transfer. Although breather elements offer some mitigation, they cannot prevent atmospheric water ingression.

A Cautionary Note Regarding Extraction FansIn some lubricant reservoir designs, extraction fans are used to prevent condensation; however, in humid environments they have the opposite effect as the increased contact between the moist air and the surface of the lubricant contributes water. While extraction fans are common in gas turbines to promote oil return to the reservoir, their usage in hydrau-lic systems is not recommended as bearing cooling is irrelevant and the approach disregards the deleterious effect of atmospheric water ingression.

“ …atmospheric contamination is the most common water ingression pathway, but is often overlooked and treated as a fixed constraint that cannot be addressed.”




WATER REMOVAL SYSTEM SELECTIONRemoving water introduced from mechanical processes can be accomplished with a variety of water removal tools that are appropriate for the type and amount of water present. In these situations, high capacity water removal systems may be required.

Atmospheric contamination, on the other hand, presents a fundamental challenge when selecting an appropriate water removal system, as most options only remove water from the lubricant without addressing the source. While most water removal systems appropriate for the type and amount of water present would work, they simply dehydrate the hydraulic or lubricat-ing fluid such that it can accept more water from atmosphere. This creates a counter-productive, energy-intensive cycle that contributes to higher rates of breakdown and results in ineffective and expensive water removal.

Carefully matching the water removal system’s capabilities with your appli-cation is critical. The water removal system must be able to remove the form of water present in your application and remove it according to the amount of water ingression. Additional considerations include initial cost, consum-able cost and energy cost. A brief review of the major types of water remov-al systems are listed below, followed by a summary in Table 4.

Water Absorbing FiltersAbsorbent filters can be used to remove a small amount of free water from lubricants. These filters are normally effective for very small lubricant reser-voirs with non-atmospheric water ingression. They have a limited capacity and would be expensive to use in large reservoirs or in cases with ongoing water problems.

Coalescing SystemsThese systems are used to remove large amounts of free water from lubricants in a short period. These units are expensive and ideally suited for extremely high water ingression rates, i.e. >1% water ingress per day. While this water removal technology is essential in situations with high water ingression rates, they cannot remove dissolved water. This can be a problem in cases where the desired water limit is significantly below the saturation point, or with oils that hold high levels of dissolved or emulsified water. Coalescing also requires that lubricants have good water separation (demulsibility).

Vacuum DehydratorThese mechanical systems are ideal for removing large amounts of water in a short period of time. These systems remove all forms of water, so they are versatile. The units are expensive and mechanically intensive. When purchas-ing, make sure the vacuum pump is very high quality and low maintenance as this is the heart of the vacuum dehydrator. Spend the extra money on systems with high-efficiency, maintenance-free designs. If dissolved gas removal is desired, only high-efficiency designs will work.

Using vacuum dehydration equipment continuously on atmospheric breath-ing lubricant reservoirs with low rates of water ingression is not ideal. While the vacuum dehydrator will maintain the oil significantly below the satu-ration point for water, the lubricant will start to pull additional water from atmosphere. This counter-productive situation is expensive and can contrib-ute to further breakdown of the lubricant. If you are using these systems in this situation, cycle their usage so they are only operating when needed to reduce energy consumption and decrease fluid stress.

Air Stripping TechnologyAir stripping technology injects dry air and heat into a fluid. Moisture is transferred into the air which is then removed under vacuum. These systems are expensive and mechanically intensive and only suitable when water ingression rates are low. The physical introduction of heat and air into the lubricating fluid is also a questionable practice as heat and oxygen are key contributors to oxidation breakdown of the lubricant.

Free Flowing Dry Gas BlanketsDry gas blankets inject dry air into the headspace above the lubricant level, which is then exhausted out the breather element. This technique is simply a reversal of atmospheric water contamination. While effective at reducing water, the quality, volume and cost of the air used are frequent issues. For this reason, engineered systems are recommended (e.g. TMR™ Air System) that produce a precise amount of clean, and very dry air (-40°C dew point) at the reservoir from a normal compressed air source. For specialized appli-cations including transformers and electro-hydraulic control (EHC) systems, free flowing nitrogen blankets are recommended.

TMR™ Air System




Free Flowing Nitrogen BlanketsFree flowing dry nitrogen blankets (e.g. TMR™ N2 System) generate and inject a small amount of high purity nitrogen into the headspace above the lubri-cant level, which is then exhausted out the breather element. Free flowing nitrogen blankets exploit the natural principle of equilibrium by keeping the atmosphere on top of the lubricant <0.01% RH, which will always be much drier than the lubricant. The free flowing dry nitrogen on top of the lubricant has an extremely high capacity to remove water and dissolved oxygen (Fig. 4).

Fig. 4—With free flowing N2 blankets, the lubricating or hydraulic fluid is always protected with high purity N2 at <0.01% RH. Water in the fluid will convert into water vapor and be vented out the breather element.

This highly effective technique reverses atmospheric water ingression. Free flowing nitrogen blankets also offer the important benefit of eliminating fluid contact with oxygen, which reduces oxidation breakdown. Over time, harmful breakdown gases including hydrogen and carbon monoxide are also removed.

Free flowing nitrogen blankets like the TMR™ N2 system, produce a precise amount of extremely high quality nitrogen (99%) directly at the reservoir from a normal compressed air source. With a typical life of 10 years, no moving parts or electrical requirements, TMR™ N2 systems are extremely cost effective (Table 4), and ideally suited to atmospheric breathing reservoirs or systems with low to moderate water ingression rates.

SUMMARYReducing water levels has been proven to extend equipment life and trou-ble-free operating windows by a minimum of 1.4x to as high as 11x. Carefully selecting water removal equipment so that it is matched to your application requirements can avoid costly mistakes and the need to repurchase the correct water removal system. In applications where the primary ingression pathway is mechanical in nature and cannot be eliminated, selecting the correct water removal system is essential for cost effective operation. When the primary ingression pathway is atmosphere, choosing a water removal system that eliminates the underlying source will not only reduce mainte-nance requirements, but also reduce rates of breakdown extending fluid life.

TMR™ AIR TOTAL MOISTURE REMOVAL SYSTEMHIGHLY EFFECTIVE, LOW COST WATER REMOVAL SYSTEMS FOR ATMOSPHERIC BREATHING LUBRICANT RESERVOIRS

OverviewWater is the most common and damaging contaminant found in hydraulic and lubricating systems. Water can exist in 3 forms: free, dissolved and emulsified. EPT’s Total Moisture Removal (TMR™) Air systems cost effectively remove all 3 forms of water from lubricants and hydraulic fluids through mass transfer which is a highly effective, non-mechanical process. Most water removal systems use heat, vacuum and pumps, which are all expensive to oper-ate and maintain, to force the separation of water from the lubricant. The TMR™ Air system exploits the principle of chemical equilibrium to remove all types of water in a much more gentle, and energy efficient methodology.

In many applications, the primary mode of water ingres-sion is atmosphere, which provides an unlimited source of water whenever the moisture content in the atmo-sphere is higher than in the lubricant. Atmospheric water ingression rates are typically low and constant, which lends itself perfectly to the TMR™ Air system. Using mechanical separation systems in this scenario would simply dehydrate the lubricant to an unsaturated state so that it can absorb more water from atmosphere. This creates an energy intensive cycle that fails to address the primary cause of water ingression.

When Results Matter

Free Flowing Nitrogen BlanketsTMR™ Air systems produce dry gas (-40°C/-40°F dew point and <1% relative humidity) using a small amount of standard compressed air at ambient conditions (75°F/24°C). The dry gas is introduced into the reservoir headspace at a point above the lubricant surface. As the clean, dry air sweeps across the reservoir, it will absorb water vapor which is forced out of lubricant as it moves towards moisture equilibrium with the dry gas.

TMR™ Air systems reverse the normal reservoir breath-ing cycle (see illustration) so that reservoirs are always discharging a small amount of dry air. In this configuration, the ingression of atmospheric water, particulate and metal ions is eliminated. Lubricant and hydraulic reservoirs operating in sea water environments, heavy industrial or agricultural regions can accumulate soluble metal ions, which are catalysts that accelerate lubricant breakdown.

Long-life, Low-cost, with Minimal MaintenanceTMR™ Air systems have very low maintenance require-ments. Two inlet air filters need to be replaced every 6 months to remove residual oil from the compressed air source, which would otherwise reduce system life. With proper maintenance, TMR™ Air systems should last 5 years or more at which time only the generation unit would need to be replaced. The total cost of ownership of a TMR™ Air system over 5 years is estimated to be $5,500 – $8,000 in total (depending on size), which in many cases is $50,000 lower than mechanical systems frequently used in these applications. That is a return on investment (ROI) of $44,500 or 809%. When you consider that one TMR™ Air system can be shared between two reservoirs that are close in proximity, the ROI is even more dramatic.

Key Issues with Atmospheric Breathing Lubricant Reservoirs• The lubricant has unlimited access to water when

atmospheric moisture levels are greater than lubri-cant moisture levels.

• Breather elements cannot reduce existing water levels.

• Breather elements, which are designed to reduce condensation, have limited capacity and cannot prevent water ingression from atmosphere via mass transfer. Note: extraction fans used to prevent condensation make this situation worse.

• Sea water and industrial environments will also contribute metal ions which increases the rate of lubricant breakdown.

Key Benefits of TMR™ Air Systems• Dry gas is generated at the source providing unlimit-

ed capacity to reduce existing moisture.• Maintains water at very low levels (<50 ppm total or

<350 ppm for EHC fluids) reducing the rate of lubri-cant breakdown.

• Free flowing dry gas is exhausted out the breather element, reversing the typical flow configuration and eliminating one of the key ingression points for water and particulate contamination.

• Normally eliminates the need for expensive vacuum dehydration equipment or disposable filter elements when water ingression rates are <200 ppm/day or solely from atmosphere.

• Very low maintenance requirements (30 minutes per year).

• Quick return on investment (ROI).

TMR™ Air System SizingTMR™ Air systems are regulated, intrinsically safe and have a manually adjusted flow control valve with flow meter. These systems are ideally suited when oil reservoirs are in small rooms where you do not want to change atmo-spheric gas levels through the addition of nitrogen. They are designed to remove up to 100 ppm water per day and sized according to the headspace volume. Reservoirs need a breather element (or suitable exhaust) and excessive atmosphere access points should be sealed. Reservoir extraction fans are not ideal in applications without bearings and should be removed if technically and logistically feasible. TMR™ systems will not work while extraction fans are operating. Contact your authorized dealer for additional information.

TMR™ N2 TOTAL MOISTURE REMOVAL NITROGEN SYSTEMHIGHLY EFFECTIVE, LOW COST WATER REMOVAL SYSTEMS FOR ATMOSPHERIC BREATHING LUBRICANT RESERVOIRS

OverviewWater is the most common and damaging contaminant found in hydraulic and lubricating systems. Water can exist in 3 forms: free, dissolved and emulsified. EPT’s Total Mois-ture Removal Nitrogen (TMR™ N2) systems cost effectively remove all 3 forms of water from lubricants and hydraulic fluids through mass transfer which is a highly effective, non-mechanical process.

When Results Matter

Free Flowing Nitrogen BlanketsTMR™ N2 systems produce ≥97% N2 gas that is extremely dry (-67.8°C/-90°F dew point and <0.01% relative humid-ity) using a small amount of standard compressed air at ambient conditions (75˚F/24˚C). The N2 gas is introduced into the reservoir headspace at a point above the lubri-cant surface forming a nitrogen blanket. As the clean, dry N2 gas sweeps across the reservoir, it will absorb water vapor which is forced out of lubricant as it moves towards moisture equilibrium with the nitrogen blanket.

TMR™ N2 systems reverse the normal reservoir breath-ing cycle (see illustration) so that reservoirs are always discharging a small amount of high purity N2. In this configuration, reservoirs will be continually insulated with a free-flowing nitrogen blanket which eliminates the ingression of atmospheric water, particulate, and metal ions. Lubricant and hydraulic reservoirs operating in sea water environments, heavy industrial or agricultur-al regions can accumulate soluble metal ions, which are catalysts that accelerate lubricant breakdown.

Moving Beyond Water Removal to Managing Oxidation LevelsTMR™ N2 systems offer the additional benefit of elim-inating fluid contact with oxygen, which along with

water and metals, comprise the 3 primary catalysts of oxidation. Therefore, these systems offer users the ability to move beyond reactionary maintenance and actually manage the factors that accelerate oxidation. By contin-ually managing water and oxygen levels and by elimi-nating metal ion ingression from atmosphere, users can lower the rate of lubricant breakdown, reducing mainte-nance requirements and extending fluid life.

Long-life, Low-cost, with Minimal MaintenanceTMR™ N2 systems have very low maintenance require-ments. Two inlet air filters need to be replaced every 6 months to remove residual oil from the compressed air source, which would otherwise reduce system life. With proper maintenance, TMR™ N2 systems should last 8 years or more at which time only the generation unit would need to be replaced. The total cost of ownership of a TMR™ N2 system over 8 years is estimated to be $5,500 – $8,000 in total (depending on size), which in many cases is $50,000 lower than mechanical systems frequently used in these applications. That is a return on investment (ROI) of $44,500 or 809%. When you consid-er that one TMR™ N2 system can be shared between two reservoirs that are close in proximity, the ROI is even more dramatic.

OIL SAMPLE SHIPPING INSTRUCTIONSWhen shipping oil samples for lab analysis, please carefully follow the instructions below. All shipping is to be prepaid.

Preventing leaking oil samples is the sole responsibility of the shipper/customer.

These additional steps are suggested as guidelines:

1. Only use proper lab sample containers; NEVER ship glass bottles or improperly sealed containers. If you require sample containers, please contact us at [email protected].

2. Fill sample bottle 90% full. There should be no air gap.

3. Secure lid and tape lid closed with electrical tape so the lid cannot loosen during transport (scotch tape or masking tape is not sufficient).

4. Place the sample bottle in a sealable plastic bag (e.g. Ziploc®).

5. Place sample inside box with appropriate internal packing material so that the sample cannot move inside the box. Paper packing materials are preferred as they can absorb oil in the event of a leak.

6. Include all relevant MSDS/SDS on the outside of the box for easy reference and a copy of them inside the box in case the box gets destroyed in shipment. If you do not have the proper MSDS/SDS, please contact EPT and we can help find the correct one.

7. On the shipping waybill, under description state “oil sample for lab testing,” indicate volume of sample and value of sample as $10 per liter.
