Wilson Hot Water manufactures stainless steel hydraulic separators or low loss headers that are compact and economical. The Wilson separator allows fast and efficient installation of primary/secondary piping for many different boilers.
Installing this unique hydraulic separator offers additional advantages of assisting in the removal of unwanted air and dirt particles, preventing their damaging effects on system components. It is especially suitable for today’s smaller boilers that tend to have a much higher flow resistance.
Primary secondary pumping is used extensively in HVAC systems to hydraulically isolate different circuits in the same hydronic system. This can be useful to save energy by shutting off or reducing the speed of pumps in areas of the system with no or low loads. This can also be useful to increase comfort by supplying areas of a system with different water temperatures or different flow rates.
To successfully accomplish these tasks the flow rates of these different circuits must be independent of each other, i.e., the flow in one circuit must not affect the flow in another circuit. This is known as decoupling or hydraulic separation. To decouple or hydraulically separate one circuit from another, an area of very low pressure drop must be created in the common piping between the two circuits.
