Resideo HYDROSEP-104-U Hydraulic Separator Union
The Resideo HYDROSEP-104-U is a heavy-duty 1.5-inch hydraulic separator union designed to maintain proper flow management between the primary boiler loop and the secondary distribution system. Engineered for high-efficiency hydronic systems, this low loss header effectively decouples the primary/secondary piping, preventing pump conflict and ensuring optimal heat transfer across varying load conditions. It features an integrated air eliminator and dirt separator to remove micro-bubbles and sediment, protecting variable-speed circulators and heat exchangers from premature wear. The unit is rated for maximum temperatures of 250°F and a working pressure of 150 psi, making it a reliable solution for commercial and large-scale residential boiler system optimization. By utilizing the HYDROSEP-104-U, technicians can achieve hydraulic balance, reduce noise caused by turbulence, and improve the overall efficiency of modern condensing boilers. This 1-1/2" NPT hydraulic separator is a critical component for contractors aiming to resolve flow rate discrepancies in complex zoned applications.
Key Benefits
- Ensures hydraulic decoupling between primary and secondary loops to eliminate pump interference.
- Integrated micro-bubble air elimination prevents corrosion and improves system heat transfer.
- Robust dirt separation captures debris and magnetite to protect high-efficiency pumps.
- Simplifies primary/secondary piping configurations, reducing installation time and footprint.
- Constructed from heavy-duty steel with a 1.5-inch union connection for high-flow capacity.
Common Questions
What is the maximum flow rate for the Resideo HYDROSEP-104-U?
The 1.5-inch model is typically rated for approximately 35-40 GPM, though specific boiler piping velocity should be verified against the manufacturer’s flow curve to prevent excessive pressure drop.
Can this separator be used with glycol/water mixtures?
Yes, the Resideo HYDROSEP series is compatible with standard hydronic fluids, including glycol concentrations up to 50%, provided the pump sizing accounts for the change in fluid density.
Does the unit include a blow-down valve for debris removal?
The HYDROSEP-104-U includes a bottom tapping designed for the installation of a drain or blow-down valve to facilitate easy system maintenance and sediment flushing.
