HVAC maker Trane, a brand of Ingersoll Rand, launched the industry's first photocatalytic oxidation air cleaning system as a standard option for cataloged air handling units.

The company's Catalytic Air Cleaning System (TCACS) is now a standard option with the Performance Climate Changer air handler, to deliver cleaner air and better indoor air quality while providing lower energy and maintenance costs and environmental impact compared with conventional air cleaning solutions.

The solution is designed to be ideal for healthcare facilities, offices, schools, airports, and other environments where indoor air quality is critical.

The TCACS blends three technologies: particle filtration, ultraviolet germicidal irradiation, and a photocatalytic oxidation (PCO) process. The system provides three steps of air cleaning:
* MERV 13 or higher particle filters provide the first stage of contaminant capture.
* Ultraviolet (UV) lights provide irradiation of the stationary surfaces such as coils and drain pans to reduce the likelihood of growth of germicidal contaminant.
* UV lights activate the catalyst on the media to enable the chemical reaction to reduce the carbon-based contaminants in the airstream.

The air handlers feature energy recovery, airflow monitoring, and humidity control options that improve the building environment and better control temperature and humidity.
