The problem
Calcium creates scale in pipes,
on appliances and other plumbing
surfaces. This leads to higher
heating and energy costs and
expensive repairs to appliances,
such as ice machines, coffee makers,
dishwashers and cooling towers
in commercial buildings.
Scale can also be a source for bacteria
to grow, which can be a health concern
in drinking water applications.
Calcium, on the other hand, is important
to human health, and supplements
are recommended if Calcium is reduced
or totally void in one's diet.
The solution
WATTS
®
Anti-Scale systems
transform Calcium ions into
Calcium crystals, which are stable
and cannot attach to pipes, sur-
faces, hardware or heat exchanger
components. The crystals are so
small they are easily rinsed away
by the water flow.
Commercial models
Note: By-pass valves are optional. KC11V3006 is optional by-pass valve for 1" systems. Maximum hardness is 25 grains per gallon at specified flow rates.
Note: Commercial systems designed for long runs and high usage. By-pass valves are optional. Maximum hardness is 25 grains per gallon at specified flow
rates.
