With higher and higher energy costs, the push to improve efficiency is here to stay and will only get stronger. To improve efficiency the hydraulic passages through boilers have gotten smaller and smaller allowing for more surface area and better heat transfer between the heat source and the hydraulic fluid. Smaller passages have caused a shift from "low-flow resistance" boilers to new "high-flow resistance" boilers. With the introduction of high-flow resistance boilers primary/secondary piping is no longer just a nice way to provide thermal shock protection but a design requirement to handle the "high-flow resistance" (head loss) in the new boilers.

The new "tighter" boilers are also more susceptible to air and sediment making their elimination even more important to hydronic system design. Up until now primary/secondary piping has been accomplish through the use of closely spaced tee's, air elimination with an air scoop and dirt elimination if done a y-strainer and with proper engineering has been successful most of the time. Now with HYDRAULIC SEPARATOR and HYDRAULIC SEPARATOR MANIFOLDS the design, piping and risk have been simplified and reduced.
The use of Hydraulic Separators allows for a clean modern design with less components and complexity in the field and therefore less potential problems.

VP Supply Corp is now stocking Hydraulic Separators in 1, 1-1/4, 1-1/2 and 2 inch with either sweat or NPT union connections and can supply Hydraulic Separators up to 12 inch and beyond for heating and chiller systems. VP Supply Corp is also stocking 3 sizes of Hydraulic Separator Manifold (Hydrolink 2+1, 2+2 and 3+1) that perform hydraulic separation and simplify secondary piping.
