16BLADDER TANKSDISPLACEMENT LIQUID FOAM PRO-PORTIONERS FOR VARIABLE FLOWRATE- BLADDER TANKS (MSL/E type, MSLtype, MSL/O type)The displacement liquid foam proportionersfor variable flowrate (bladder tanks)are utilized for foam systems with differentindependent foam outlets which can worksimultaneously or separately.The displacement liquid foam proportionersfor variable flowrate regulate automaticallythe correct foam extract admixingpercentage to a variable water flow in arange 1:8 (for example, the same foamimageproportioner is suitable for admixingautomatically the properfoam compound percentagein a foam system with 8monitors both if only 1monitor is working singularlyand if all monitorsare working simultaneously).Compared to the Venturiproportioners, the high advantage of thedisplacement liquid foam proportioners isthat they don't require the installation of afoam compound pump (the admixing ofthe foam compound to the water flow isautomatically provided by the membrane inthe bladder tank).Another advantage of thedisplacement liquid foam proportioners isthat they include also the foam compoundstorage tank. Caccialanza & C. displacementliquid foam proportioners for variableflowrate are supplied:• with vertical tank and membrane fixedonly at the top of the tank (MSL/E type)• with vertical tank and membrane fixedat the top and at the bottom of the tank(MSL type)• with horizontal tank (MSL/O type)In the versions:• with single or doubletank• with capacity of thetanks from 400 lt. to13.000 lt.and are available forfollowing water/premixflowrate ranges:• DN 4" - 200÷1.600 lt/min• DN 6" - 400÷3.200 lt/min• DN 8" - 800÷6.400 lt/min• DN 10" - 1.200÷9.600 lt/min• DN 12" - 2.000÷16.000 lt/min• DN 14" - 2.500÷20.000 lt/minThe MSL/E, MSL and MSL/O type displacementliquid foam proportioners forvariable flowrate are provided with a foamcompound admixing percentage regulatingvalve which allows the regulation of theadmixing percentage between 1% and 6%.www.caccialanza.eu
