Heat Exchanger uses Descalex Polymer

1.Biosol  cleaner RXSOL-20-2019-025 contians oil soluble formula it doesn't effect Titanium plate and Nitrile gasket.

2.Descalex Polymer (RXSOL-40-1048-025)  is derivative form or ACIDIC polymer, it doesn't react with Titanium metal and Nitrile gasket

3.Recirculation is best option to clean heat exchanger, And if volume is 2797 litres on the sea water side means same or aditional 30% volume tank required to circulate the liquid. And required percentage of Biosol is 5 - 10 % of total liquid volume which means 100 to 150 Ltr BIOSOL is more then suffiecient to circulate in this case  to clean as contaminatied with heavy oil. And after circulation of BIOSOL, remove all contaminated water from heat exchanger and tank. Then take other sea water / fresh water to dose Descaler Polymer, Its dose ratio is completely depends on deposition of scale inside the plate of heat exchanger. The solid mass of mineral deposits approximate mass calculation will help to use proper volume of RXSOL-40-1048-025  Descaler. As per gallon in concentrated form of RXSOL-40-1048-025  has the ability to dissolve approximately 1.5kg of scale mass   So  3 to 20 percent  of total volume depending on deposition of scaling materials required. 150 Ltr to 600 Ltr  descalex polymer can be use to clean scale deposits. After use of RXSOL-40-1048-025  a  0.5% solution of Alkalinity Control infresh  water should be used for neutralization.
