The Digi TBN test kit now handles cylinder oils with base number up to 100

Parker Kittiwake has launched an updated Digi TBN test kit, designed to provide a rapid indication of total base number (TBN) depletion in scrape down cylinder lubricants with a base number range up to 100.

Recent guidance from engine manufacturers recommends the use of higher BN lubricants in newer engines to help prevent the damaging effects of corrosive wear, particularly when slow steaming. Therefore, major oil companies are now adding higher BN lubricants to their product portfolios.

A recent service letter from MAN Diesel & Turbo recommended Parker Kittiwake’s Digi TBN test kit as an alternative to sending samples to a lab for testing. The Digi TBN test kit update is part of Parker Kittiwake’s ongoing research into the problem of cold corrosion, the next planned development being a test kit to measure the level of corrosive wear within used scrape down oil. This will allow ship operators to monitor specific levels of both metallic and corroded iron in cylinder oil, giving a comprehensive overview of the operating conditions within the cylinder chamber.

Dr Steve Dye, business development and marketing manager, Parker Kittiwake said: “With the latest Parker Kittiwake DIGI TBN test kit, ship operators using high BN lubes now have the ability to test residual TBN levels in their oil. This gives operators peace of mind by ensuring they are following OEM guidelines to prevent cold corrosion. This quick and simple test can be used in conjunction with laboratory testing, but gives an on-board reading within two minutes to meet OEMs’ testing recommendations. Frequent TBN testing is important for residual cylinder oil, as it is continuously exposed to acidic combustion products that should be neutralised before they corrode engine parts. Consequently, maintaining a correct alkaline reserve is critical in preventing unnecessary harm to expensive components within the engine, such as cylinder liners.”
