The Frigg branchpipe is developed to match the compact measurements of the Balder fixed monitors. The branchpipe has a self-inducting valve and an air inlet to aspirate the foam. A unique design of the branchpipe’s interior allows the creation of superior foam quality. Instead of admixing the foam concentrate at a single entry, there are several tubes inside the branchpipe in which the water stream is separated. As the foam concentrate is admixed at several points the result is a homogenous solution. This allows also the branchpipe to be relatively short, as there is no need to work the foam after the mixing point.
