GENERAL INFORMATION

TheCOMBIPCS110DUALfromColdJetpresentsarevolutionaryalternativetoexistingDryIceproducing
andblastingmachinesinthatitcombinesDryIceproductionandDryIceblastinginONEMACHINE.
TheCOMBIPCS110DUALProvidesanon‐stopsupplyofhigh‐densitypellets.Thesourceofrawmaterialfor
theproductionofpelletsisliquidcarbondioxideconservedatlowtemperatureinastoragetank.Theliquid
CO2flowsintothemachineinaregulatedmannerandistransformedintoCO2Snowwhichisthenpressed
throughanextruderplatebymeansofthehorizontalmovementofahydraulicallydrivenpiston.


Theproduceddryiceisthenledintothetwobuffertanksandblastedwhenactivatedbythecontrol

Ateverystart‐upthehydrauliccylinder=(G01‐G1‐MO1)forextruderpistonisextractedtoitsmax.position
toextrudetheCO2snowinthechamberincaseofanemergencystopormachineerror.
LiquidCO2isfedfromanexternalCO2tank(notpartofthisdescription–seesupplierinformation)through
aninsulatedpipetotheCOMBIPCS110DUAL.Itisrecommendedtouseagasseparatortoeliminate

TheshutdownsequenceensuresthatCOMBIPCSDUAL110isstoppedinaproperpositiontoempty
extruderchamberfromdryicesnowandavoidmoistureintheextruderchamber.Thehydrauliccylinder

Thehydrauliccylinder=(G01‐Q3‐MO1)forextruderplatechangerisinmiddlepositionandallvalvesare
closed.
Undertheshutdownsequencethetwohoppertanksarealsoemptied.Thisoccurswhenthetwodiverter
valves=(C01‐Q1)and=(C02‐Q1)changespositionandwillblastthedryiceintotheCO2drainpipes.Thisis
