Technology Comparison - EPT Ion Exchange Patented Resin Based vs Particulate Deep Mechanical Filtration Used

There are 2 main categories on filtration technologies for turbine lube oil maintenance and varnish removal.??Particulate based, and ion exchange resin based.

Particulate based technologies

Uses compressed cellulose to remove fine particulate generated when varnish forms.?Because varnish formation occurs only when an oil becomes saturated with oxidation material, this device has to wait for varnish to form before it can offer any value.???Because an oil’s saturation point is temperature dependent, varnish is dissolved in the oil when the turbine is operating and converts into a solid during shut down and when the oil is allowed to cool.???These machines uses an oil cooler in an attempt to force varnish into the solid form so the cellulose can remove it.??While this offers benefit once varnish starts to form, it does not offer any preventative measure.??Because the cooler is added, the flow rate of these systems is relatively low and designed to exchange the oil volume <0.5x per day which is sub-standard.

The pros and cons :

+ Cost of technology is low.

+ Basic design

-?Has to wait for varnish to form before it can start to work

-?As a particulate removal device, it is only effective when oil temperature is cool and when varnish converts into a solid

- Does not work 100% of the time, works best when turbine is not operating.

- Does not remove acids, reduce additive consumption, or extend lubricant operating life.

EPT Soluble Varnish Removal System

Opposite of particulate removal technology. Uses engineered ion exchange resins called ICB that are designed to remove varnish in its original dissolved form.?SVR with ICB technology works at all operating temperatures of up to 90C which has the benefit of removing and preventing varnish at 100% of the time.?By using ion exchange resin technology, the flow rate of SVR is faster and designed to exchange the oil volume 1-2x per day for ideal performance.

By removing the molecules that should not be in the oil, the chemistry is maintained at the original lubricant conditions.?By removing oxidation material as it is generated, the oil properties including acid number can be maintained.?This improves the efficiency of the additive system, reducing the loss rate in additives extending lubricant life.??By removing dissolved impurities, the lubricant is maintained in an unsaturated condition at all temperatures, flows, and pressures in the mechanical system. This ability to keep the oil in a highly unsaturated state, prevents the possibility of varnish from every forming.?The ability of SVR to maintain chemistry properties separates it from other systems in the market.???The technology is patent pending under the World Patent Cooperation Treaty in over 40 countries.

SVR combines high efficiency particulate filtration as a second filter step that maintains particle contamination at target levels.?Because solid contamination removal filters require a higher flow rate, SVR is designed to have a flow rate of 2x compared to the flow rate for varnish removal.?In this manner, flow rates of each filter technology are optimized.

EPT SVR is an engineered approved system using certified parts and pressure vessels.?It is designed to last 25 years with a pump and motor replacement every 8-10 years.?

Caution: All Ion Exchange Filters are NOT Created Equal

In our lives, we often fall prey to generalization. A great example, coffee is coffee. Coffee beans all look the same when roasted. The appearance in your cup is the same when brewed. Coffee is all the same. Hold on a minute. Did you know that there are actually dozens of different coffee bean varieties? The difference between each one is significant, and it’s helpful to understand when choosing your cuppa Joe.

Generalizations are a result of assumptions and what do we know about assumptions? They make an ______?of “U” and “ME”. I will leave that blank for you to fill in on your own.

Let’s shed the lens of generalization and adopt the lens of complete and transparent understanding. Let’s learn the facts and use the facts to make effective filtration decisions.

Fact #1: Ion-exchange is defined by Merriam-Webster as ‘a reversible interchange’ that is ‘used especially for softening or demineralizing water, the purification of chemicals, or the separation of substances.’

Fact #2: Standard ion-exchange filters and ICB? ion-exchange filters share nothing in common other than the above listed noun,?ion-exchange,?and subsequent definition.

Fact #3:?ICB??is a patented ion-exchange resin technology, engineered specifically for lubricant applications to provide superior acid-scavenging capacity (3x more acid removal capacity) and varnish- removal that other ion-exchange resins cannot – period.?

Fact #4: ICB? is the only ion-exchange resin technology that removes varnish in phosphate ester systems.

Fact #5: ICB? acts like a bulletproof vest for your machine, offering a sacrificial surface that gets between the oxidation in your system and its critical mechanical surfaces.

To be matter of fact, ICB? punches above the ion-exchange weight class, offering best in class chemistry and unmatched results for your critical equipment time and time again.

In summary, avoid generalizations. Just as every coffee is not created equal, every ion-exchange resin technology is not created equal. Learn the facts and use the data to drive decisions.?
