The Anguil Dual-Bed Regenerative Thermal Oxidizer (RTO) consists of two insulated, vertical thermal energy recovery chambers connected by an inverted "U shaped" insulated oxidation chamber. Flow diverter valves are located under the thermal energy recovery chambers to divert the process air flow into and out of the chambers. The thermal energy recovery chambers are filled with ceramic media that provides for the recovery of up to 95% of the oxidation temperature. The complete operation of the oxidizer system is controlled by a Programmable Logic Controller that optimizes both the VOC destruction efficiency and the thermal efficiency.
