  •  Cost effective, easy to apply and use.

A. Dosing Procedure

FALCHEM SCALE X must be used diluted at a proportion of 1 liter for every 4-9 liters of water. Dilution must not exceed this proportion as it may alter the inhibiting effect of the solution. Note that after the application of FALCHEM SCALE X, a 1% solution of ALKALINITY CONTROL must be used to neutralize the treated surface area.

B. Cleaning Procedure

Preparation: Before the application of FALCHEM SCALE X, remove Tin, Zinc, and Aluminum. Lead and galvanized parts/components from the surface area to be treated. Additionally, rinsing of the
contaminated area is suggested in order to eliminate sludge and other loose deposits.


FALCHEM SCALE X may be used either at room temperature, or in order to accomplish quicker results, it can be heated up, but the temperature must be no more than 55°C.

The methods used are the circulation, soaking and spreading. Circulation is applicable to boilers, evaporators, condensers, heat exchangers and generally closed systems that have the capability to circulate at a temperature of approximately 45-55°C, for 6-15 hours with a solution of 10-40% of FALCHEM SCALE X in water. Keep in mind that the strength of the solution is analogous to the degree of contamination/accumulation. Soaking is usually applicable in open or closed systems that do not provide circulation. In these cases, two or three cleaning trials are recommended beforehand. Generally, a solution of 20%, at 45-55°C, should be used; it must not stand still, and should have periodic agitation. This ensures constant reaction rate. At the same time we must maintain the strength of the desired acidity by adding FALCHEM SCALE X and fresh water, periodically, in order to make up for the lost volume proportion due to steam loss and surface reaction. Spreading is applicable for general cleaning use on large surface areas, by conventional means such as a brush, sponge or a mop with FALCHEM SCALE X either diluted or not, depending on the degree of contamination and the kind or type of deposition. After the completion of the cleaning process, regardless of the method used, rinse with plenty of water and neutralize (only for
the metal surface areas) with 1% solution of ALKALINITY CONTROL.

Note that during application, inflammable and / or toxic gases may be liberated. In this case, adequate ventilation is necessary.
