Ultrasonic Cleaner Cleaning Fluid Temperature(s) Concentration
Kemet 12 Solvit 3 40°C 40%
Kemet 12 Tap water 50°C 100%
Versa 120 Dryer N/A 70°C 3 minutes

Process for cleaning plate heat exchanger:

The plate heat exchanger was cleaned in a small bench top unit (Kemet 12) placed standing up, the reason being the high concentration. The bath was filled with tap water then diluted with the cleaning fluid Solvit 3. The part was placed standing up and set for a cycle time of 1 hour, the part was then rinsed and inspected. One side had fully cleaned up, with all the scale removed. The other side has changed colour slightly but still heavily contaminated/stained. The part was cleaned in 60 minutes cycles until 100% clean. It took a total time of 8 hours in the ultrasonic to fully clean both sides with no staining/scale remaining.

% Satisfactorily Cleaned: 100%

Comments: Using a higher concentration will reduce cleaning times.
