WATER CONDITIONING

Furnishing the steam generator with treated water to reduce scale formation is important. Scale formation will reduce steam output, cause premature component failure, and shorten equipment life. Most water supplies contain scale producing minerals such as Calcium and Magnesium. As steam is generated, the minerals remain and dissolve into the water. As the concentration of these minerals increases past a certain point, they precipitate from the water and coat the inside of the steam generator, heating elements, and water level sensors. Because of the high temperature of these surfaces, the precipitated minerals bake onto them and become very difficult to remove.

This may cause several problems:

1.Reduced heat transfer efficiency.

2.Premature heating element failures.

3.False readings from water level sensors.

These problems are common to any manufacturer's steamer regardless of design, but they can all be minimized by furnishing the steam generator with treated water.

Other factors affecting steam generation are iron content, amount of chloridation and dissolved gases.

The desired water properties can best be achieved by using a properly maintained water treatment

system.

The water level probes in the steam generator use ions in the water to detect the water level. Do not use fully demineralized or de-ionized water since it is "non conductive" and the water level can not be detected.

The use of strainers, or filters will not remove minerals from the water.

Water supplies vary from state to state and from locations within a state. Therefore, Vulcan recommends that a local water treatment specialist be consulted before the installation of any steam generating equipment.

Steamers that operate over a long period of time without the benefit of a water treatment system, which have developed a heavy scale build up, should be cleaned before using the system.
