Introducing a transformational step forward in commercially viable, sustainable cooling. A revolutionary HVAC solution that eliminates global-warming refrigerants and provides building owners with a sustainable solution that significantly reduces CO2e over the life cycle.

Rethink HVAC
with the TTAP platform


Our TTAP (Terminal Treatment of Air with Peltier) offers an HVAC solution that provides fully demand- based cooling and heating without the need for refrigerants or a hydraulic network. The TTAP is a modular solid state platform that can be integrated into existing building retrofits or as a feature in new build construction. It enables the use of only partially treated air ventilated throughout the building, and cools or heats specific to the occupants’ settings. This new approach delivers superior operating efficiency and costs, seamless installation and unparalleled end-user health and comfort benefits.

Environmentally Sustainable Cooling

The new innovative technology builds on the Peltier effect and electric cooling. It offers an HVAC solution that significantly reduces greenhouse gas emissions and provides fully demand-based cooling and heating. Laboratory benchmark technology testing and LCA analyses of the first TTAP units have shown a dramatic reduction in CO2e compared to traditional HVAC systems, including fan coils and chilled ceilings.

No harmful refrigerants

Up to 15% CO2e savings at installation

16% CO2e savings annually via operation

Superior operating costs and efficiency

The TTAP is a modular solid state platform that can be integrated into existing building retrofits or as a feature in new buil construction, delivering as much as 18% savings to install and operate over its lifetime. The air handling approach enables the use of fresh air ventilated throughout the building, which is then cooled or heated by the TTAP units, based on occupant specific settings. This method provides a combination of energy efficiency, comfort, silent operation, air quality and attractive aesthetics.

As the global leader in solid state cooling technology, Phononic is driving the world to a more sustainable way to cool. Together with Halton, a global leader in HVAC innovation and indoor air comfort solutions, Phononic is bringing to life the TTAP platform. The TTAP seamlessly integrates into commercial HVAC infrastructure and completely eliminates global-warming refrigerants, providing building owners and real estate developers a sustainable solution that, for the first time, dramatically reduces a building’s CO2e over the typical life cycle of a commercial installation.

The very first TTAP technology installation was introduced in an 8500 m2 commercial office building in Paris, France.
