Descalants or Descaling Agents are chemical compounds that effectively dissolves, disperse or purge the scales, rust and soil deposits from heat exchangers and pipelines by means of re-circulation method, fill and soak method or immersion method. A descalant is always designed by keeping in mind the type of deposit and metallurgy of the system. Proper Corrosion Inhibitors are added in descalants to avoid damage to system metals.

After acidic descaling of system, it is important to passivate and neutralize the system with proper Passivating Agents for avoiding chances of flash rusting after descaling.

In some cases Scale Softeners and mechanical means like brushing and scrubbing of tubes is also required for heavily fouled systems.

Descaling is a labor oriented job and requires system downtime. Hence, the use of alternatives such as Online Descalants and Antiscalants are getting popular.

Condenser Descalant

CHEMTEX'S condenser descalant is a heavy duty liquid descaling agent for removing hard mineral scale deposits and metal oxide deposits from the condenser tubes.

The descaling compound has an inbuilt corrosion inhibitor for providing corrosion protection to the metal during descaling operation. In addition to this is a wetting agent for quick removal of scale deposits with deep penetration method.
It contains defoaming agent to suppress the heavy foam that is generated during the process of descaling.
It surpasses the performance of other offline descalants (such as Nalclean 8940 of Nalco).

Application :
Condensers, Cooling Water Heat Exchangers, Radiators, Gear Boxes, Injection Mouling Machines, Blow Mouling Machines, Housings, D.G.Sets etc.

Specification:

Chemical Type	Blend of Acidic Chemical Compounds
Form	Liquid
