Corrosion and incrustation inhibitor for steam and hot water systems with softened or partially demineralized feed water

Mode of action:

POLYDOSIL 2418 is a blend of an organic oxygen binder with alkaline dispersing polymers.
POLYDOSIL 2418 binds oxygen and thus prevents corrosion attacks in all plant components in contact with water, even in the absence of thermal degassing of the feed water.
Due to the distribution coefficient of the vapor-volatile active ingredients, the entire system incl. Steam and condensate network protected and effectively prevents corrosion and deposit formation.
Existing corrosion products and deposits are gently dispersed and broken down. Heat transfer is improved throughout the plant, resulting in significant savings in water, energy and chemical costs.

Environmental sustainability:

POLYDOSIL 2418 is phosphate-free and ecologically and toxicologically safe.
Further information can be obtained from the EU safety data sheet.

Application/ Dosage:

POLYDOSIL 2418 is added to the boiler feed water as a concentrated or diluted solution without any further additives. The quantity to be used depends on the water quality and the condition of the plant and is determined accordingly by the technical advisor.
The detection of POLYDOSIL 2418 in the system can be done either by a simple rapid test or a photometric test.

Delivery terms:

The product is supplied in liquid form in containers of 30, 60 or 210 liters.
