About UsContact

The growth of microbiological organisms is greatly encouraged by the warm, incubator- like environment of modern water based cooling systems and to a lesser extent heating systems.

These organisms can form a gummy slime mass which attracts silt, dirt, and other suspended solids flowing through the system. Microbiological growth, and the solid particles can severely restrict heat exchanger tubes, and thus reduce heat transfer efficiency. Also, these deposits can cause localized corrosion.

Chlorine is often used to help eliminate the growth of micro- organisms. However, chlorine kills only on contact with the micro-organisms. It simply oxidizes the surface organisms, but not the deposit.

The disadvantage of chlorine is that it can be corrosive.  Proper biological control maintains a balance between micro-biological growth and corrosion.  Other non-oxidizing biocides are used to help against acclimation to chlorine.

The best results can come from a biocide study which evaluates biocide effectiveness for a specific system.
