Recirculating Thermocatalytic Air Purifier for Collective Protection

摘要

MesoSystems Technology Inc. is developing a recirculating air purifier that deactivates chemical and biological contaminants without the need for replaceable filters or adsorbents. The thermocatalytic air purifier (TCAP) is based on three enabling technologies: (1) lightweight, high-effectiveness heat exchangers; (2) aerogel-based insulation; and (3) Honeywell's Military Air Purification catalyst, which is proven capable of oxidizing a wide variety of chemical agents. TCAP prototypes have demonstrated high single-pass destruction efficiencies for simulated chemical and biological agents. This paper describes the development history of the TCAP, the enabling technologies, the design tradeoffs that were considered in its development, and prototype development and testing.
