Key Features and Benefits

Application and Dosage
Prepare a solution of 10% W/W chemtex’s liquid boiler descalant in preheated water (preferably) at 70-80oc. The descalant solution should be prepared 10-20% in excess of the system hold up volume. Re-Circulate the solution using an acid compatible pump (with polypropylene impeller) for maximum of 6hours. After descaling is completed, flush out the solution and rinse once with plain water. Passivate the system with 2% W/W passirinse® solution in water and recirculate for an hour at ambient temperature. Passivation is done to avoid flash rusting after descaling. Flush out the solution and return system to normal service.

Note: If a boiler is to be kept idle for some time, it is recommended to fill it with 1% solution of passirinse, for system preservation against rusting.
