I would like to start a discussion around the best electrostatic oil cleaner on the market today.
Does anyone own either a Kleentek or Oilkleen machine?
Are you happy with it's performance?
Has anyone compared the two?
Pros and cons
Lets see if we can collectively come up with a sensible answer.

Dear macabf,
Ihave been working with electrostatic oil cleaners since 1992 and have found them to be very effective for removing small particles from lubricating and hydraulic oils. Before we go too far we would like to know more about the application. not one type of filter is best for all applications.
What type of machinery is this? what are the results of the oil analysis for the past. and what problem are you trying to solve.
Please send us some more information and we will try to help, or use the email if this is private. Applications rely do matter.

The turbine oil is mineral ISO 68
Last year we found the two safety servo valves failed to open due to varnish build up around the spool, this resulted in considerable amount of damage to the steam turbine rotor blades, the cost was several million dollars.
We immediatly embarked on a program to improve filtration and monitor the results.
To date we have installed one CC Jensen filter and placed an order for one Kleentek oil purifier.
The original filtration consisted of re-cleanable 20 micron nominal elements, which gave 21/19/14
The idea was to compare technologies fine filtration against electrostatic, but we have a new contender; Oilkleen
So I was wondering whether anyone has compared the three or the two electrostatc brands.

Dear macabf,

for steam turbines, I would hesitate using the current electrostatic designs which have a 500 ppm water limit. This can be a real issue when you need it the most.

The ISOPur unit does an equal job as far as varnish but does not have a water limitation.

The CC Jensen is a fine idea but I have the same reservations about the water here.

I would go back and ask the vendors what happens if the water content at the inlet of their system is 1% for an hour?

Good Luck.

Hello Frank and Gerald

We have been operating a CC Jensen system on a GE 7EA turbine and have had some amazing results. The initial oil quality was some of the worst we had seen and progress in cleaning to oil seemed to be taking some time. Varnish does not significantly affect the differential pressure since it is adsorbed by the cellulose and not filtered out so the customer was reluctant to change elements as recommended. In order to show the customer what result continued circulation and regular element changes would produce we used a smaller filter on an isolated sample of oil and circulated it taking regular samples over several hours. The varnish potential went from critical to undetectable. Overal with the CJC filters the ultra-centrifuge went from 8 to 1, the colorimentric went from 166 to 0, and the micro-particle count went from 1,000,000 to 158.

As for steam turbine applications, use the CJC PTU model using BLAT elements and water in the oil will not be an issue, in fact the PTU is designed to remove and automatically discharge the separated water.

To view the varnish tests :CJC removes varnish and click on "accelerated test results"

Each CJC element can hold over 8 pounds of varnish and when you see the amount separated by the ultra-centrifuge you can see why it takes a few elements to remove it "all".

If you have any questions contact me at harv@klassenhydraulics.com

Thanks

Very good results Harv, We can do the Ultra Centrifuge but I haven't enough information on the Colorimetric test method or micro particle count.
Our systems tipically have <50 ppm of water.

Hello Frank

If you have a look at the visual comparisons of the oil progress of varnish removal you can see that for all practical purposes when the oil is back to clear and bright the varnish is all but gone. Be sure the samples are cool before you compare, it does made a difference. The rapid removal of the varnish from an isolated sample supports the observations that circulating the clean oil also removes the varnish from the interal components of the system and thus can take much longer to totally clean up the oil. There can be many pounds of varnish to remove in systems like this. Once the system is cleaned up continued filtration with the CJC filter elements and regular yearly changes will ensure that the varnish will not build up again.

The best approach to varnish control on any system is to install CJC filtration before startup and varnish will never be an issue. With regular filter changes, frequent and expensive varnish testing is really not necessary. Regular visual comparisons are often a good check to see where the oil is headed since normal oil analysis reports give no indication of varnish problems.

We emphisize "at least" yearly element changes since varnish does not significantly affect the differential pressure when it is adsorbed and due to the extremely high dirt capacities of the CJC elements they will often not indicate on dirt for several years.

Please contact us at Harvor at Klassen Hydraulicsfor any questiond or more information.

Thanks

Dear Paul
I have sent you 3-4 mail to get the information about the GREEN MACHEEN, But i didnt get any mail from you .
Pls send me the complete information(capasity,types of oil,prices of different types of machin with different capcity).you can mail me on neet862007@gmail.com or technoservice@mtnl.net.in
Awaiting for your reply .

Thanks & Regards
