Dirt in tubes of seawater side

White scales attached on the seawater side of air coolers of many vessels. We found that in most cases, the main component of the scales is calcium carbonate and there is also a small amount of calcium sulfate. Therefore in most cases, if you dissolve the calcium carbonate the scales will be removed.

However, if the amount of scales is large enough to block the tube, the cylindrical scale will usually have calcium carbonate on the outside (the side that is in contact with tube) and calcium sulfate in the center (part that seawater passes through). Calcium sulfate is easier to be formed when the temperature goes higher.

When the amount of scales increases, the contact area of scale and cleaner is very small and a longer time of dissolution is required. Calcium sulfate cannot be dissolved by an acid cleaner.

RXSOL-54-1048-020 is a powerful dissolving agent of calcium carbonate. Therefore, it is better to use RXSOL-54-1048-020 to do circulating cleaning at an early stage before the scales build up and block the tube, or regular cleaning is recommended as well. It is impossible to do a circulating cleaning when the tube is completely blocked.

while Dirt attached on air-side fins of air coolers are a mix of carbonaceous particles such as soot and oil mist of unburned fuel components can be clean by RXSOL-16-0009-025. ( www.rxmarine.com/air-cooler-cleaner-25-ltr )

Carbonaceous particles can be removed by alkaline cleaners and oil mist can be removed by oil based cleaners. However, it is very difficult to remove the mix of these substances. If you use an alkaline cleaner, oil will repel the water based alkaline cleaner; if you use oil based cleaner, carbonaceous particles will get in the way and stop oil from being removed.

This cleaners designed to remove both carbonaceous and oil simultaneously. An effective cleaning method is to immerse one side to remove the loose stains first, and then immerse the other side. This method can efficiently remove dirt and prevent swollen dirt peeled from fins from blocking the spaces between fins.

Also Suitable for Cleaning of BOILER and Cooling Water deposition...

Scales are very damaging to the boiler because they interfere with the heat transfer and can lead to overheating and eventually, boiler rupture , To increas usable life of cleaned equipment , it is safe and effective way to remove scale deposits from all types of water-cooled and water-heated equipment. This descaler specifically formulated and developed to rapidly clean mineral scale from passages in water-cooled or heated equipment. It improves Plant Efficiency, Lowers Cost, Conserves Energy, Decreases Down-Time.

Uniqueness of RXSOL-54-1048-020 ::: ---

RXSOL-54-1048-020 Descaler has the ability to dissolve approximately 1.5kg of calcium carbonate scale per gallon in concentrated form. It does not need to be heated up during cleaning. The uniqueness of this Descaler allows you to clean some equipment while still in operation utilizing a minimum of your own personnel.
