Direct injection system advantages

simple to operate easily adjusted proportioning rates highly accurate proportioning maintains desired mix ration despite changes in water flow and

pressure proportioning across wide flow range 20 -1600 Lt no foam contamination of pump or appliance water tan no loss of pump flow or pressure number and length of hose is

limited only by the pump capacity concentrate injection will not be interrupted when filling the foam
