Total Lubmarine has launched Tech’Care/TCC, an iron test kit offering comprehensive analysis of cylinder drain oil and significant time-saving benefits.
Tech’Care/TCC has been developed by Total Lubmarine’s technical team, in collaboration with its research scientists and is in line with the recommendations of all major two stroke engine manufacturers. It is completely self-sufficient and is able to accurately determine dissolved iron content in cylinder drain oil, resulting from the effects of excessive acid corrosion – also known as cold corrosion – on the cylinder liner wall.
The quantity of dissolved iron in cylinder drain oil made known by using the test kit can be combined with the residual base number of the oil to monitor and fine tune the amount of cylinder lubricant needed to counter the effects of cold corrosion. If these effects can be neutralised, a cylinder liner’s life can be significantly extended, delivering significant cost savings.
Regular use of Tech’Care/TCC enables the collection of useful data on an engine, which can be checked and monitored by Total Lubmarine’s worldwide laboratory service and global network of marine engineers and technicians. This process enables Total Lubmarine to accumulate detailed knowledge of individual engine and fleet performance and advise on optimising lubrication and cost saving.
Jean-Philippe Roman, Total Lubmarine’s technical director comments:
“Tech’Care/TCC is a very useful product that we know will make life simpler for our customers. Beyond its superb technical, monitoring capability, the test kit can save up to five hours when testing an average six cylinder engine, compared to other equipment currently available on the market. There is a great demand on marine engineers’ time and we are pleased that we can offer a product that offers serious time-saving advantages.”
To ensure that the test kit measures only corrosive wear, during the testing procedure, samples are placed in a carrousel where a magnet is used to attract iron particles that might be present in the drain oil as a result of abrasive wear.
Non-hazardous reagents that have been carefully selected and engineered are added to drain oil samples, which react with dissolved ferrous ions in the mixture. The reaction results in the solutions changing colour. The solutions’ colours can then be determined and correlated automatically to numeric iron concentrations by an optical device.
This method is very accurate and does away with problems that occur using devices reliant on the human eye. The optical device used to determine colour and iron concentration does not suffer from variation in perception.
