Comprehensive Chiller-Heater Systems

Trane® Comprehensive Chiller-Heater systems, featuring electric heat pumps, provide cost-effective, energy-efficient, reliable cooling and heating, while reducing carbon emissions. Ideal for larger buildings, especially those with a central plant, these pre-engineered system solutions make electrified HVAC systems easier to specify and implement.

Key Benefits:
  • Cleaner electricity generation: fuel transformation for building electrification can help meet tighter regulatory requirements, avoid carbon penalties and achieve sustainability goals
  • Electrified heat pump systems can reduce or replace fossil fuels for heating in buildings, cutting down on direct carbon emissions
  • Comprehensive Chiller-Heater systems maximize performance by combining knowledge and expertise into the controls, equipment selection, and system layouts

High Performance

Exploit dramatic improvements in heat pump heating capabilities to help buildings function better and reduce carbon emissions. Chiller plant controls provide sequencing and advanced optimization strategies to reduce energy use.

Featured System Components

Choose from packaged or modular air-to-water heat pumps

Ascend Air-to-Water Heat Pump

Comprehensive Chiller-Heater Systems include the Ascend® Air-to-Water Heat Pump which can operate in either heating or cooling mode. Multiple units can be used when heating and cooling loads are expected to occur at the same time, sized to deliver the right combination of capacity and efficiency with robust performance. 

Thermafit Modular Air-to-Water Heat Pumps

These easy to install units are ideal for tight spaces or where the footprint is limited, like the roof of a tall building or a freight elevator. Combine individually controlled modules to create a single, larger heat pump. Modular design enables you to scale to match your building's heating or cooling load.
