Oil filtration services using Activated alumina balls.!

How do I know if I am using the right filters for my system? 

This is a common and very valid question. The first part of the answer lies in determining the level of cleanliness and the conditions required by the system.
 If the lube -oil is common to all components in the system, the cleanliness level should be set in accordance with the most contamination -sensitive component.

The component manufacturer should have that information, but don't count on it. Your owner's manual may also have the information. also click here. 

 If not, your oil analysis lab recalls extensive records about contamination levels for all major components (valves, bearings, gear boxes, etc.). Can the Total Acid number (TAN) be reduced in an existing lube – oil system?

The answer is a qualified yes. Hard-working lube oils and hydraulic fluids change their characteristics with time. Acid is one by - the product of aging.

 Other factors are temperature, water, levels, wear particles and additive depletion. Individual lubricating brands contain different additive packages. Blenders attempt to have their products satisfy the application.

Acid is the by -product of complex chemical reactions within the system. Unchecked acid "feeds" on itself, thereby raising TAN numbers.

Highly oxidized fluids reveal high acid numbers. Virtually all lube-oils, mineral-based and synthetic, will respond to "conditioning" techniques which are applied off -loop to the main reservoir utilizing Fuller's Earth, activated alumina, enhanced activated alumina or ion -exchange.

 Filter systems should operate at low flow rates that increase the contact time between acidic fluids and the conditioning media. We will recommend suitable products based on your lube -oil system.

If a system displays early acid warnings, off -loop conditioning should be considered. We suggest tracking TAN numbers for 2 -3 sample periods. Conditioning techniques should also be accompanied with RBVOT analysis that will monitor additive packages. Buy best quality desiccant activated alumina from this Link

In general, it is not practical to reduce acid levels to "zero". However, acid can be kept within acceptable limits through timely and continuous conditioning, verified by regular oil analysis TAN monitoring.

 Why are there three water phases within a given lube-oil system? There are several reasons.

Much of the explanations tied to the chemistry of lubricating oil - both mineral and synthetic. Lube-

oils, However, oil has a water - saturation point beyond which excess water becomes either entrained (emulsified) or totally free.

 Therefore, we have to deal with dissolved, emulsified and free -water. Temperature has a huge influence on water solubility in oil.

 At higher temperatures, oil dissolves greater amounts of water. Emulsified water displays variable characteristics. Additives and blender formulations affect performance. Read this: activated alumina balls for water treatment.

Free -water is visible in most mineral oils.  Karl Fischer (ppm) oil analysis readings report the total water content of the sample which may consist of free, emulsified and dissolved water.

 The breakdown of free, emulsified and dissolved water is not reported on these tests.

2. What are realistic and attainable "dryness" levels (low water PPM)

The primary tools for water removal are water -absorbing cartridges and bags, centrifuges, vacuum distillation, coalescing and dehumidification. Each has a distinct water-removal concept. It is important to identify water's source and to quantify it, if possible.

In steam turbines, water invasion may be continuous. Heat exchanger leaks are typically progressive. Unprotected reservoirs open the door to airborne moisture contamination. also Check this: activated alumina  for water filtration.

New oil may not be water-free. Fundamental to remedial efforts is the "dryness" target that is appropriate for a lube -oil system. Equipment makers, blenders and oil analysis labs have recommendations. Once the targets are established, water removal techniques can be selected and put into action. 

Why isn't new oil clean and ready for use? This is a question that must be answered by your lube -oil supplier. Contamination can be controlled by the blender but at a cost. 

Filtration is the best protection from the tanker to on-site storage. Some oil merchants will certify a cleanliness level at the time of delivery. Also Check: activated alumina for air dryers

However, after on -site arrival of new lube -oils, operators should exert disciplined care to prevent further contamination. What are the solutions to sticky servo-valves?

One cause of sticky servo -valves is the oil's condition. Problem oils are usually highly oxidized that are caused by high temperatures, additive depletion, water and other contaminants that aid the oxidation process. Increasing total acid numbers (TAN) are certain indicators of pending problems.

Highly oxidized oils display visible contaminants that appear as gummy and gel -like deposits on internal valve surfaces and spool -valve filters. want to buy best quality LDPE bags for pharma packaging ?then click here.

 Some operators call it "vanishing". Corrective action, other than dumping the entire oil batch, is off -Loop filtration and conditioning. The objective is to curtail TAN increases. Read this: Activated alumina F200 for arsenic fluoride removal

In some cases TAN numbers can be partially reversed, thereby increasing the oil's productive life. Depending on the oil, TAN reduction is achieved via one or more of the following media:

How Activated Alumina Deal with Transformer oil filtration services.!

Transformer oil filtration process:-

Electrical transformers work to change over the high voltage vitality created at power plants and change this vitality to usable lower voltage vitality, which runs customer and business control needs.
These transformers are an indispensable bit of the power framework, which by definition comprises of
The power era and transmission lines which flawlessly give a persistent supply of dependable,
Predictable vitality paying little heads to the end client control necessities.
Transformers contain paper-oil protection frameworks intended to avert overheating. After some time, water may collect in transformers because of holes in gaskets and welds, ill-advised fixing, poor support, lacking drying at the season of generation, and normal maturing of protection materials inside the transformer.

Collected moisture and other byproducts of insulation degradation lead to reduced effectiveness in energy transmission and eventually dielectric breakdown, resulting in power outages.

According to the U.S. Department of Energy, power outages and other interruptions in the electricity
Distribution system cost the U.S. economy at least $150 billion annually; an annual cost of about $500
for each man, woman, and child.

Moisture in transformer oil is one of the most common causes of breakdown. Moisture advances insulation degradation and causes decreased dielectric strength and increased mechanical stress on equipment.

It leaves transformers susceptible to corrosion, oxidation, fractures, restricted oil flow, increased heat and aeration, among other harmful side effects. Also, check this: -activated alumina adsorbent for water filtration.

Simply, transformer life is measured by the health of its insulation system. For every doubling in moisture content, transformer life is reduced by half. The water content in transformer oil must be kept to a level of 10ppm or less.
Regular maintenance of water content in transformer oil is essential.
To keep moisture out, transformers may include conservator or inert gas systems and online oil filtration systems.
Oven drying or vacuuming the system also removes moisture, but requires excessive time, labor, and

Laboratory tests prove the best way to restore and maintain transformer oil properties is a
Combination of adsorbents, desiccants such as Activated alumina

 Removes water in transformer oil to less than 10ppm, more than expanding transformer life and providing greatly improved energy transmission to the power grid.
