Unitor™ Descaling liquid™

DESCALING LIQUID for Any descaling work

Pack Size - 25 LTR

Unitor™ Descaling Liquid is a powerful acid-based Descaler that removes scale, rust, and cargo residues from boilers, heat exchangers, evaporators, and cargo holds. Formulated with corrosion inhibitors for enhanced metal protection.

Unitor™ Descaling Liquid is a concentrated hydrochloric acid-based descaler formulated for efficient removal of rust, scale, and mineral deposits from boilers, heat exchangers, condensers, evaporators, and cargo hold bulkheads. It contains corrosion inhibitors to minimize metal degradation and wetting agents for deeper penetration into deposits.

 

This fast-acting cleaning solution is ideal for marine, offshore, and industrial applications, effectively breaking down water scale, rust deposits, and cargo residues such as cement and lime wash. The product is compatible with Unitor™ Chemical Cleaning Units for large-scale descaling operations and should always be handled with proper safety precautions.

How to Use

1. Descaling Process:

  • Use circulation method for large systems or immersion bath for small components.

  • If equipment is contaminated with oil, pre-clean with Unitor™ Seaclean Plus™ or Unitor™ Enviroclean™.

  • Always mix acid into water (never the reverse).


2. Recommended Dilution:

  • Mix 10–30% solution in fresh water, depending on scaling severity.

  • Use plastic containers only.


3. Post-Treatment Neutralization:

  • After descaling, rinse with 0.5% Nalfleet™ Alkalinity Control™ solution for 2–4 hours to neutralize acidity and passivate steel surfaces.


Safety Precautions: Always follow SDS guidelines, use protective equipment, and ensure proper ventilation to prevent exposure to acidic fumes and gases.
