Electric Catalytic Oxidizers


What is an Electric Catalytic Oxidizer?

An electric catalytic oxidizer (ECO) is a catalytic oxidizer that uses electric heaters instead of gas burners to heat the dirty air to the catalyst operating temperature. This flameless option makes the ECO an ideal emissions control system for facilities without ready access to natural gas or those concerned with the potential hazards of gas-burning systems. Additionally, the ECO makes a great solution for companies looking for a more sustainable air treatment technology.

Benefits of Electric Catalytic Oxidizers

Like all catalytic oxidizers, ECOs use a catalyst to convert Volatile Organic Compounds (VOCs) into carbon dioxide, water vapor and thermal energy at a lower temperature compared to other thermal oxidizers. Benefits of using an ECO for oxidation include reduced harmful emissions, a flexible unit design footprint and lower installation and operating expenses.


  • Reduced Harmful Emissions - A significant benefit of this system is reduced harmful emissions and their contribution to smog as there are no combustion products of natural gas and no formation of NOx. Additionally, the formation of CO is significantly reduced to minimal levels.  


  • Flexible Unit Design - ECOs are also an appropriate system for facilities that have a limited footprint or a desire to place their air pollution control system in a specific location. The design of the enclosed ECO makes it lighter and more compact than traditional oxidizers; it does not occupy a lot of space and can be easily skid or roof-mounted. This unit is smaller, requires less maintenance due to fewer moving parts and is more easily accessible than typical thermal oxidizers.


  • Lower Installation and Operating Costs - An ECO is easy to install when compared to other air pollution control technologies. This system yields lower installation expenses since there is no need for natural gas or the installment of corresponding gas lines. Without a burner, facilities also don’t have to worry about extensive system maintenance or the required yearly NFPA burner inspections.

Electric Catalytic Oxidizer Controls

Each unit Pollution Systems engineers includes a modern set of automated controls and the necessary programming to effectively start-up, shut-down and safely operate the unit. Our automated controls require minimal operator interaction and can seamlessly integrate with existing facility processes.

Control package features include: a VFD, PLC, HMI with touch-screens, safety interlocks, temperature and pressure controls, timers, relays, switches, and air-conditioned control panels. Our customizable system controls can accommodate operation in classified/hazardous areas, remote HMI operation and may be managed through a plant’s distributed control system (DCS).

If you are looking to upgrade your controls or repair your existing Electric Catalytic Oxidizer, our technical services division PolSys Services can assist in repairing the make and model of any Electric Catalytic Oxidizer system
