This used CECO Adwest Retox 6,000 regenerative thermal oxidizer (RTO) has 6,000 scfm capacity. In very good condition internally, and a little UV weathered externally. Treated emissions from a heatset web offset printing press. The RTO includes a two-chamber design, with random packed ceramic media and a dual poppet (switching) valve configuration.  Now off line and available immediately

CECO Adwest Retox RTO systems are designed to provide one of the lowest utility costs (fuel & electric) of any leading oxidizer system. It is a simple RTO with over-sized beds to reduce pressure drop.

This regenerative thermal oxidizer has the following features:

  • Maximum design flow – 6,000 scfm @ up to 350F process emissions
  • Ceramic media (saddle ) heat exchanger (95% thermal effectiveness)
  • Pneumatic poppet valve for flow direction changes through media
  • Main RTO fan with 30 hp TEFC motor and an Allen Bradley Powerflex 400 VFD
  • Maxon Kinemax 3.0 burner for heat-up
  • Allen Bradley SLC 500 PLC
  • Allen Bradley Panelview 300 operator interface
  • Yokogawa chart recorder
  • Combustion blower with 3 hp TEFC motor
  • Isolation damper with electro-pneumatic actuator
  • Inlet start-up/Fresh air damper with electro-pneumatic actuator
  • Stand-alone exhaust stack (24’ from grade) w/test ports
  • Fuel gas injection for high fuel efficiency and low NOx operation
  • Complete owner’s manual with electrical and mechanical drawings
