Centrifugal Fans for Thermal Oxidizers

Thermal Oxidizers (TO), including Regenerative Thermal Oxidizers (RTO’s), provide air pollution control through source reduction for safety, compliance, and comfort in industrial facilities and the surrounding environment. The oxidizer is like a huge furnace, turning the hazardous bypass gasses into water vapor through combustion.

The function of the centrifugal process air fan in the oxidizer is to force or draw the bypass gases through a series of chambers that follow alternating heating and cooling patterns to break down volatile organic compounds (VOC’s) and hazardous air pollutants (HAPs) before releasing the emissions into the environment in accordance with the requirements of the Environmental Protection Agency’s Clean Air Act.

In addition to the main process air fan, oxidizer applications also require a combustion air blower, which you can read about on our Combustion Air Blower Application page.

Primary Industries for Thermal Oxidizers

Pollution control is required across many industries that produce hazardous substances or contaminants as byproducts of their operations. Common industries that employ thermal oxidizers for pollution control include:

  • Animal Feed
  • Automotive
  • Building Materials
  • Chemical Processing
  • Chrome Plating
  • Food Processing
  • Metal finishing
  • Oil & Gas
  • Paint & Surface Coatings
  • Pharmaceuticals
  • Printing, Packaging & Labeling
  • Rubber & Plastics
  • Semiconductor & Electronics
  • Wastewater Treatment

 Fan Selection & Specification for Thermal Oxidizers

Because of the emission requirements, thermal oxidizers are a core function of the industrial operation, making the process air fan mission-critical to the overall production process. That means it’s important to select the right fan technology.

The required air flows call for efficient industrial fans that can withstand high temperatures and corrosive gases. That makes our backward-curved BCHS BCMS, and BCLS models the top choice in many cases. These fans can achieve up to 81 percent efficiency! Additional fan technology options include the Backward Inclined (BIHS) and Radial Tipped (RTHS) designs.

We build high-efficiency, high-temp, and corrosion-resistant industrial fans & blowers specially designed for each Thermal Oxidizer application.

Fan Designs Commonly Used on Thermal Oxidizers

To select the right fan for your Thermal Oxidizer, you’ll need to know the airflow volume, temperature (as high as 1800°F), static pressure, and how toxic the gas stream is in parts per million (PPM).

Fan Arrangements

Thermal Oxidizers and RTOs most often use an Arrangement 8 direct-drive on the process fan. This modular pedestal design offers stability in addition to saving time and money at installation.

Accessories & Design

When it comes to design and accessories, it’s all about protecting and optimizing operations, maintenance, and life of the fan and bearings.
