Corrosion

Untreated Hot Water Boiler has mud-like deposit as a result of corrosion.

The corrosion of metals is a natural process that occurs when these materials come in contact with moisture and oxygen.  This same process occurs within your heating and cooling systems.

Deposits

Boiler tubes coated with scale (mineral deposit) as a result of poor Water Treatment Control.

Deposits are physical materials that are left behind as water is used for the purposes of heating and cooling.  These deposits canbe comprised of natural minerals found in city make-up water, debris left behind as a result of corrosion that has taken place, or organic material such as dead bacteria, leaves, algae, etc.  Deposits can form a film, or scale, that covers the heat transfer surface of your equipment.

Corrosion and deposits lead to reduced efficiency and a dangerous operating environment.  A proper Chemical Water Treatment Program can control this corrosion and tie-up the minerals before they deposit to maintain efficiency and saftey.

Biological Activity

Bacteria, Algae and other biological growth is common among open cooling systems (any water holding system that is directly exposed to the air).  A lack of control of these biological contaminants can lead to increased rates of corrosion, deposit problems, and health hazards.
