Offered as a standard option for the company’s cataloged commercial air-handling units is a photocatalytic oxidation (PCO) air cleaning system. The Trane Catalytic Air Cleaning System (TCACS), now a standard option with the Performance Climate Changer™ air handler, is engineered to deliver cleaner air and better IAQ while providing lower energy and maintenance costs and environmental impact compared with conventional air cleaning solutions, claimed the company. Equipping an air handler with a TCACS can help reduce certain biological organisms such as spores, bacteria, and viruses. The air cleaning system provides a unique blend of three technologies: particle filtration, ultraviolet germicidal irradiation, and a PCO process. This system provides three steps of air cleaning: MERV 13 or higher particle filters, ultraviolet (UV) lights provide irradiation of the stationary surfaces such as coils and drain pans to reduce the likelihood of growth of germicidal contaminant, and UV lights activate the catalyst on the media to enable the chemical reaction to reduce the carbon-based contaminants in the airstream. In addition to air cleaning systems, the air handlers feature energy recovery, airflow monitoring, and advanced humidity control options that improve the building environment and better control temperature and humidity, while optimizing performance, said the company.
