Ultrasonic Cleaner Cleaning Fluid Temperature(s) Concentration
MI80 cleaner Optical 2010 70°C 125G per Litre

Process for removing landfill gas residue:

The MI80 cleaner was filled with the same fluid that was used in the first test; the cleaner was degassed for 20 minutes and allowed to heat up to 70°C. The cylinder head was loaded in the basket and submerged into the tank. The contamination on this particular cylinder head is heavier than the last and is a fairer representation of a typical part. The head was checked after each 60 minute cycle, with a total cleaning time of 8 hours until 100% of the contamination had been removed. The part was then hosed down with tap water to rinse off any residue and dried manually. Results: 100% of the contamination has been removed but the process time is long, Optical 2010 can be used at a higher concentration of 200G per litre which should improve the results and reduce the process time.
