Catalytic Combustion Corporation can provide you with a two tower RTO and VOC DRE of 95%, three tower RTO and VOC DRE of 99%, or with high performance multiple tower, patented valve common shaft EUROCAD design with a VOC DRE of 99.5% and extreme high reliability.

Each RTO system is designed for the conditions of a specific application. Sizes range from 2,000 SCFM to 100,000 SCFM. Please see specifics below.

Compact modular two bed RTO system Heat recovery efficiency up to 95% VOC destruction efficiency 95% (99% with optional VOC peak compensation chamber) VOC load 0 - 25% LEL (with optional hot gas bypass) Economical modular design Structured ceramic heat transfer media with low pressure drop and low electrical cost Pneumatically operated poppet valves Easy maintenance

Compact modular three tower RTO system Heat recovery efficiency up to 95% VOC destruction efficiency 99% VOC load 0 - 25% LEL (with optional hot gas bypass) Structured ceramic heat transfer media with low pressure drop and low electrical cost Pneumatically operated butterfly valves

RTO technology offers operational cost and other performance advantages over recuperative thermal technologies such as direct thermal oxidizer or a catalytic oxidizer.

The RTO’s heat recovery system is designed to recover up to 95% of available thermal energy for reuse in preheating the incoming process airstream. This design reduces the fuel consumption significantly if compared with conventional thermal recuperative oxidizers.
