Water Filtration
The purpose of water filtration is to keep the Ice
Flaker clean and operating efficiently.
The value to the user is reduced operating cost
due to less maintenance, improved
performance and a greater return on
investment as result of extended asset life.
There are three primary categories of
contaminants that damage and cause the Ice
Flaker to operate inefficiently. They are listed
here in order of importance with regard to
impact.
1. Scale
2. Sediment
3. Chlorine
Scale
Scale or fouling is the accumulation of
unwanted material on solid surfaces to the
detriment of function. Scale is primarily made
up of calcium and magnesium hardness
compounds.
It’s estimated that scale is responsible for 70%
of unscheduled maintenance, inefficient
operation, and down time.
Scale forms on wetted surfaces, accumulates in
tubing and fittings and interferes with
operation.
Sediment
The formation of scale from dissolved minerals
is made worse by sediment.
Sediment is suspended particles of dirt, silt and
other fine particulate matter that act as a
catalyst for scale to form.
Sediment can be detrimental to the condition
and performance of the Ice Flaker. Particulates
cause added wear on parts and can clog valves
and impede flow.
The effects of scale and sediment can be very
destructive to the Ice Flaker.
Chlorine
Chlorine is the most common disinfectant used
to kill pathogenic organisms in order to make
our water safe to drink. However, residual free
chlorine in water can contribute to pitting, rust
and corrosion of stainless steel.
If not removed from water, chlorine mixes with
moisture in the Ice Flaker and Ice bin to form a
mild hydrochloric acid. This acid can cause
surface rust to form on stainless steel surfaces
in one to two years.
