Overview

Energy-efficient, year-round zone comfort from new and existing air handlers with 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.

Load-Responsive Zone Comfort Management

Each hydronic branch conductor directs the flow of hot or cold water to a thermal area. It adapts to changing heating and cooling loads, area by area, as needed throughout the day. By utilizing milder hot water supply temperature, the conductor enables steadier supply-air temperatures—no more cycling on/off with very hot air.

Enhanced sustainability benefits

Trane's hydronic branch conductor delivers a 35% efficiency gain by heating adequately with milder, 105°F or lower hot water. This prevents system energy waste by stopping adjacent zones from fighting with each other over temperature set points. Plus, conductors integrate easily with building automation systems for enhanced energy management.
Reduced installation cost and complexity

With the hydronic branch conductor, 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.
