Resideo HYDROSEP-105-U Hydraulic Separator Union

The Resideo HYDROSEP-105-U Hydraulic Separator Union is a critical component for optimizing hydronic system piping by effectively decoupling primary and secondary circuits. This 2-inch union-connected separator eliminates hydraulic interference between multiple circulators, ensuring that the flow in the boiler or chiller loop does not conflict with distributed load zones. By acting as a low-pressure loss header, it stabilizes flow rates and temperature differentials, which is essential for the performance of high-efficiency condensing boilers and radiant heating manifolds. Beyond flow management, the internal geometry of the HYDROSEP-105-U facilitates air and dirt separation, protecting heat exchangers and system components from localized overheating and debris accumulation. Whether used in commercial chilled water loops or complex residential heating, this low pressure drop hydraulic separator provides the necessary primary-secondary piping isolation to prevent pump deadheading and ghost flows, resulting in a more balanced and reliable HVACR installation.

Key Benefits

• Ensures proper hydraulic separation to prevent pump conflict and system imbalance.
• Features a 2" union connection design for simplified field installation and maintenance access.
• Integrated functionality for coalescing air separation and sediment removal to maintain fluid quality.
• Optimizes heat transfer by maintaining steady flow across the primary heat exchanger.
• Compatible with a wide range of Glycol concentrations and temperature ranges in heating and cooling applications.

Common Questions

How does a hydraulic separator improve system efficiency?
By decoupling the production and distribution circuits, it allows each pump to operate at its design flow rate without being influenced by the pressure or flow of other pumps in the system.

Where should the HYDROSEP-105-U be installed?
It should be installed between the primary energy source (boiler or chiller) and the secondary distribution manifold to create a point of zero pressure differential.

Can this unit handle high-debris systems?
Yes, its design allows for the separation of micro-bubbles and solid particles, which can be purged to prevent damage to circulators and control valves.
