Trane Catalytic Air Cleaning System (TCACS)


The Trane Catalytic Air Cleaning System can be retrofitted to your existing system and is a cost effective way to improve indoor air quality in places such as departments with immunocompromised patients, waiting areas and locations that suffer from engine exhaust fumes in your healthcare facility.

How it works

  • TCACS seamlesslessly integrates three technologies to effetively improve building IAQ 

    • MERV 13 rated filters remove majority of 0.3 micron ultrafine particles and larger
    • Ulltraviolet Germicidal Irradiation (UVGI) is used to damage or kill various organisms on surfaces and in the airstream
    • Photocatalytic Oxidation (PCO) eliminates volatile organic compounds (VOCs) and small biologicals


Key benefits include

  • Significant reduction of microbiological elements (viruses, bacteria and fungi/mold)
  • Reduction of organic odors caused by VOCs like engine exhaust fumes
  • Highly efficient particle removal
  • Minimal maintenance and longer lifecycle than other air cleaning technologies
  • Available in a variety of configurations

    • Easily retrofit into existing air handling systems
    • Factory engineered and installed in new Trane air handling units
    • Curb-mounted for use with existing and new rooftop packaged systems
    • Portable and duct-mounted versions
