Need a reply
1.Is Biosol cleaner RXSOL-20-2019-025) compatible with Titanium plate and Nitrile gasket?
2.Is Descalex Polymer (RXSOL-40-1048-025) compatible with Titanium plate and Nitrile gasket?
3 If the plate heat exchanger volume is 2797 litres on the sea water side.That's the side where there has been contamination with heavy oil , how many litres of bio sol cleaner and Descaler Polymer do we need to order?
Need your feedback to the above queries
Thanks Regards

Dear Sir,
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.
