Water Quality

It is essential to supply the steam generator with water that will not form scale or cause
corrosion. Even though the steam generator is engineered to minimize scale formation
and the effects of corrosion, their development depends on the quality of your water and
the number of hours per day you operate the equipment.
Most water supplies are full of minerals and chemicals which are not suitable for use in
a steam generator.
Water quality varies from state to state and city to city. It is necessary that you know
and understand the quality of the water you are using. Your water utility can tell you
about the minerals and chemicals in your water. The water going to the steam generator
should be within these guidelines.
WATER QUALITY REQUIREMENTS:
Containment
Water Supply
pH
7 to 9
Total Dissolved Solids (TDS)
30 to 60 ppm
Hardness
less than 60 ppm
Chlorine and Chloramine
less than .1 ppm
Chlorides
less than 30 ppm
Silica
less than 12 ppm
Undissolved Solids
less than 5 microns
In order to accurately choose the correct water treatment solution, a water quality test
has to be performed. If a “Free Start-up” is requested, the ASA will perform a water
quality test and Unified Brands (UB) will be able to suggest the best solution for your
water quality. If it isn’t, your local manufacturing representative can coordinate this for
you.
After the “Free Start-up” is performed, UB will add an additional 1-year parts and labor
warranty. If UB suggests a water treatment system, the system is purchased from UB,
installed and maintained, water related service issues will be covered for the duration of
the warranty period.
