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detrimen tal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.
