Plate Heat Exchanger Cleaning Acid

The cleaning solution tank should be at least twice the volume of the heat exchanger.
Plate heat exchanger cleaning acid. Acid cleaning is only recommended if you have a lot of trouble getting the debris out of the plate heat exchanger. Some chemicals that can be used are nitric acid citric acid or phosphoric acid. Where the temporary inlet and outlet are at different heights the outlet should be the higher of the two to ensure that the heat exchanger is fully flooded with cleaning solution. The use of formic acid for plate heat exchanger cleaning effect is better because adding buffer and surface membrane active agent formic acid can also reduce the corrosion of the plate.
Make sure you protect your eyes from splash back when cleaning with any type of acid. Set up a circulation around the heat exchanger using an external pump and tank. Above is a tranter 06t2 before and after our cleaning procedures. Wcr service invented the cleaning process that s mimicked by other heat exchanger companies even oems.
We built our reputation by utilizing select cleansing methods for different applications returning the heat exchanger specifications back to nameplate performance. In the test process do not disassemble the heat exchanger place a water injection valve on the inlet and outlet of the secondary network of the heat exchanger inject 3 5 oxalic acid solution in the water tank into the heat exchanger clean it by the circulation pump for 3 4 hours.
