Affordable servicing with TDL Service Contracts help to protect your investment long term.
Oil samples are taken as part of a TDL Service Contract to help monitor component performance/ condition.
One of those samples taken is hydraulic oil. Hydraulic Oil forms the life blood of your Atlas material handler and to keep your investment running at it’s best, regular and thorough servicing is key. Oil sampling also allows you to remain proactive and tackle potential issues before they become a costly problem.
One of the oil samples taken as part of a TDL Service Contract is a TAN test, this is to check the quality and cleanliness of the oil. Clean oil keeps components running at their optimum and identifies when action is required and indicates preventative maintenance to keep costs down.
What is a TAN Test ?
TAN (Total Acid Number) is a measure of the quantity of acidic compounds present in an oil sample.
What oil samples are usually tested for TAN levels ?
TAN is usually determined on used hydraulic oils but can also be used to test any samples where TAN level is determined to be an important measurement tool.
What can a TAN value tell you ?
TAN levels are monitored for increases, indicating increases in the acidic by products generated as the oil ages or production of oxidation products from normal use. Abnormal increases in TAN levels can also indicate issues with the running of the machine or problems with the suitability of the oil for the application. Also as a means of assessing oil degradation, additive levels and age of oil.
What can increasing TAN levels do if left unchecked ?
Increasing and high TAN levels can lead to the formation of Varnishes, Lacquers, Sludge & Gums.
All of these compounds can have detrimental effects on machinery, such as uneven gear wear, increased drag/energy demand and increased temperatures due to lack of lubrication on metal surfaces. Restricted oil flow is also possible leading to oil starvation to metal parts and increased oil pressure. Valves, piston rings and cylinders can become choked up with deposits leading to increased friction and temperature and seizure, in severe cases.
How is the TAN level determined ? (The Science Part..)
The standard way of determining the TAN value of a sample is by titration analysis, with the endpoint determined by either potentiometric or photometric titration. The sample is dissolved in a solvent mixture and titrated with a known strength solution of alcoholic potassium hydroxide, using a glass electrode, coupled to a voltmeter/potentiometer, the titration endpoint is reached when a well defined inflection point in the data, is reached.
