Trane Catalytic Air Cleaning System (TCACS)
To address the air cleaning aspect of IAQ, Trane developed a hybrid air cleaning system called the Catalytic Air Cleaning System (TCACS) which utilizes multiple technologies to control particulate (dust) along with gaseous airborne contaminants that can cause odors.
Achieving good indoor air quality requires consideration of the entire conditioned air system. Energy consumption also plays a part in the equation.
Trane Catalytic Air Cleaners use a photocatalytic oxidation (PCO) process that uses a titanium dioxide treated media activated by UV-C energy to create a hydroxyl field that can oxidize and reduce microorganisms to a non-viable state. This technology can also be effective on converting some VOCs (volatile organic compounds) to a less harmful product. The process is analogous to the effect a catalytic converter has on the exhaust gases from gasoline powered automobiles.
Bottom line: Trane Catalytic Air Cleaners, in combination with traditional particulate filtration, can provide improved indoor air quality without the potential high pressure drop and motor horsepower penalties of other air cleaning options like activated carbon filtration.
Trane Catalytic Air Cleaners are available in a variety of configurations:
- Factory-engineered and installed on new Trane cataloged and custom air handlers
- A retrofit module designed to upgrade existing air handling systems
- Curb-mounted for use with small to medium-sized packaged rooftop equipment
- Portable and duct-mounted versions available from Trane Parts Centers
