Adwest Technologies'Flameless Operation RETOX RTO Regenerative Thermal and Catalytic Oxidizer systems have provided  industry with affordable, cost effective air pollution solutions for control of VOCs since 1988. Adwest's RETOX RTO oxidizers have been installed successfully on over 800 applications including paint spray, finishing, chemical processing, printing, web converting, coil coating, composites, plastics, surface coating and microelectronics processes from 500 scfm to over 240,000 scfm flowrates.

Adwest also pioneered the successful application of RETOX RTOs for corrosive halogenated chemical processes since 1989 using various stainless and titanium alloy metallurgies for chemical, wastewater treatment and soil remediation applications. Other leadership firsts include the utilization of flameless RTO combustion (provides virtually zero NOX byproducts), and development of simple low-cost RTO poppet valves with soft step seating to provide zero leakage RTO flow control. This allows the RETOX RTOs to achieve 99 percent and greater VOC DRE without the need for third chambers or puff capture modules. A major Adwest RTO advantage is its low ceramic heat transfer media pressure drop, saving up to 40 percent on RTO fan electric and natural gas usage. The virtual total shop assembly and compact, low profile modular design provides rapid installation schedules for clients. RETOX RTOs only require one fan to operate, not two or three fans that others require for operation, reducing maintenance time and costs. 

Adwest's RETOX RTO Oxidizers provide industry with a specialized, focused RTO supplier that brings a proven, reliable, mature design with extremely low operating and energy costs, all at an affordable price for cost effective VOC compliance.
