The Regenerative Thermal Oxidizer (RTO) has long been recognized as an efficient way to thermally treat pollutants. Conventional RTOs, however, are designed with multiple valves that direct air flow in and out of each oxidation chamber in the system. The multiple valve design is prone to maintenance problems, decreased efficiency and poor reliability over time.

The innovative patented design of EISENMANN's Valveless Regenerative Thermal Oxidizer (VRTO) eliminates the need for multiple valves and chambers and replaces many moving parts with a single, simple rotary distributor. EISENMANN also offers a compact, skid mounted system providing the same, patented valveless technology as the VRTO, with reduced installation time and the smallest footprint available per CFM of gas treated.

EISENMANN is the Ethanol Industry's "supplier of choice" with over 79 Valveless Regenerative Thermal Oxidation (VRTO) systems installed throughout industry and operating on-line since 2003 and have met guaranteed emissions performances, verified by annual stack testing.
