What Is Chemical Cleaning?

Chemical Cleaning or so called Acid Cleaning or Descaling, is a term described in two phases.

The first is the Pickling or so called Descaling phase, where an acid-based solution that is completely compatible with the materials of construction of the system, is used to dissolve mill scales, rust, operational scales and other contaminants. 

The second is the Passivation phase, where the surface is made inactive after the acid clean, to prevent the surface from re-oxidisation through generating a temporary protective layer of Gamma Haematite.

The removal of such scales and rust that formed during the system operation will recoup not only by keeping your system intact but by substantially reducing the operating cost bills as well. 

The right supplier for all chemical cleaning needs

CCS has its branded inhibited acid formulations customised to each job in hand.

The acid type, concentration, operating temperature and dwell time of cleaning varies from clean to clean, depending on the observations and chemical analyses of our qualified and experienced engineers and technicians.

We carry out a variety of Acid Cleaning activities on various systems such as Heat Exchangers(Coolers, Condensers or Evaporators), Charge Air Coolers, HRSG (Heat Recovery Steam Generator) and WHB (Waste Heat Boiler), Water and Fire Tubes Boilers, all sizes of Pipelines, Vessels, Tanks, HVAC systems, Cooling Towers, Fin Coolers and others, all by re-circulation methods using our professional and specialised  equipment of pumps, hoses, tanks, fittings, and others or by dipping in our tanks or using our professional Foaming machines .

We have a mobile laboratory to test on the spot, the chemicals parameters required to have better control and understanding of the chemical reaction under way. Our laboratory is equipped with all the required calibrated testing devices, reagents and is ran by a qualified Industrial Chemist or Chemical Engineer.
