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.

HTF System Online Descalant

Htf system online descalant for chiller water, brine or glycol is an organic chemical compound that are non-corrosive and removes scales and deposits from the system without degrading the properties of fluids. During this process while the scales are being removed the system does not need a shutdown and continues to work. Htf system online descalant is a revolutionary product with excellent benefits in terms of economy, productivity, time, labor and product effectiveness.

htf system online descalant allows the user to remove scales from the heat exchangers and pipelines without plant shutdown and taking hassle of offline cleaning and descaling by making a descaling circuit and then passivation of system.
