Displacement Liquid Foam Proportioners For Variable Flowrate - Bladder Tanks
The displacement liquid foam proportioners for variable flowrate (bladder tanks) are utilized for foam systems with different indipendent foam outlets which can work simultaneously or separately.
The displacement liquid foam proportioners for variable flowrate regulate automatically the correct foam extract admixing percentage to a variable water flow in a range 1:8 (for example, the same foam proportioner is suitable for admixing automatically the proper foam compound percentage in a foam system with 8 monitors both if only 1 monitor is working singularly and if all monitors are working simultaneously).
Compared to the Venturi proportioners, the high advantage of the displacement liquid foam proportioners is that they don't require the installation of a foam compound pump (the admixing of the foam compound to the water flow is automatically provided by the membrane in the bladder tank).
Another advantage of the displacement liquid foam proportioners is that they include also the foam compound storage tank..
