- Self-contained controller, preprogrammed with sequence of operation
- Butterfly valves, with 0% leakage, wired back to the controller
- Area branches only require two pipes
- 105°F or lower hot water
Hydronic Branch Conductor
Hydronic Branch Conductor
Enables energy-efficient, year-round zone comfort from new and existing air handlers with hydronic heat pump HVAC systems.
The Hydronic Branch Conductor enables sustainable, effective heating and cooling that can improve comfort and reduce installation and energy costs in hydronic heat pump systems.
- Simplifies zone comfort by using the same branch piping for cooling and heating.
- Adapts to changing heating and cooling loads, area by area, as needed during the same day.
- Enhances energy efficiency by heating spaces effectively with milder hot water temperatures.
- Use in retrofits (two- or four-pipe buildings) or new buildings with chilled water terminal units.

Introduces load-responsive zone comfort management
Each Conductor directs the flow of hot or cold water to a thermal area.
Adapts to changing heating and cooling loads, area by area, as needed throughout the day.
Utilizing milder hot water supply temperature enables steadier supply-air temperatures. No more cycling on/off with very hot air.
-
Enhances heat pump systems’ sustainability benefits
Delivers a 35% efficiency gain by heating adequately with milder, 105°F or lower hot water.
Prevents system energy waste by stopping adjacent zones from fighting with each other over temperature set points.
Integrates easily with BAS for enhanced energy management.
-
Reduces installation cost and complexity
Retrofits repurpose existing branch cooling supply and return water piping for both heating and cooling distribution.
In new construction, 50% fewer coils, valves, piping and joints reduce cost and labor.
Logic for distributing hot or cold fluids into zones is built into the Conductor controls, saving time for technicians.
