What is a Hydraulic Separator?

A Hydraulic separator, or sometimes called "Decoupler" or "Common Pipe" is simply a large diameter pipe with 2 inlets and 2 outlets on each side of the pipe. Friction loss between inlet and outlet on each side of the separator is close to zero.

Hydraulic separator is shipped with Automatic Air Vent, Drain Valve, Magnesium Rod and a set of mounting accessories. 


What is Hydraulic Separator Used for?

Most Heat Producing Equipment such as Boilers, Air to Water Heat Pumps, Chillers, etc... are designed to operate at a constant flow (primary Hydraulic Circuit) while heat consuming equipment water supply network (secondary Hydraulic Circuit) serving Fan Coil Units, Air Handling Units, Infloor Heating Loops, etc.. are variable flow networks even when individual components on that network are constant flow. Since the pressure loss through the Hydraulic Separator is almost zero, Pressure/Flow variation of the secondary hydraulic circuit does not affect the pressure/flow of the primary hydraulic circuit. Hydraulic Circuits are used in applications where primary hydraulic networks are required to operate at constant flow.
