Bronx Regenerative Oxidiser (RTO)

At Bronx, we engineer and manufacture high-performance thermal oxidisers tailored to the demanding needs of today’s industries. We offer both Regenerative Thermal Oxidisers (RTOs) and Recuperative Thermal Oxidisers (learn more about Recuperative Oxidisers here).

The key difference between the two lies in how they recover heat. Regenerative oxidisers use ceramic media beds to transfer heat between exhaust and incoming air, while recuperative oxidisers use a metal heat exchanger, typically a shell and tube design, to preheat the incoming air with the exhaust gases.

Whether you’re managing volatile organic compounds (VOCs) from paint curing lines, chemical drying processes, or other industrial applications, our Regenerative Thermal Oxidisers (RTOs) offer a proven solution for air pollution control and process heat recovery.

Why Your Process Needs a Regenerative Thermal Oxidiser (RTO)

Processes like paint curing, chemical drying, metal coating, and printing generate emissions that include VOCs and hazardous air pollutants (HAPs). Left untreated, these emissions can cause health hazards, environmental damage, and regulatory non-compliance.

Our oxidisers are designed to thermally destroy pollutants through high-efficiency combustion, converting them into safe, inert byproducts like carbon dioxide and water vapor—keeping your operations clean, compliant, and sustainable.

Trusted Across Industries

From automotive and aerospace to chemical processing and metal finishing, Bronx oxidisers are trusted by global manufacturers for their reliability, energy efficiency, and seamless integration with existing thermal equipment.

Regenerative Thermal Oxidisers (RTOs)

The Regenerative Thermal Oxidiser delivers superior energy efficiency by passing exhaust gases through refractory ceramic beds, which recover and reuse thermal energy. These systems can achieve thermal efficiencies up to 95%.

How It Works:

  • The process begins when exhaust gases from the oven or production line enter a canister filled with hot ceramic bricks.
  • The heated gases move into the central destruction chamber (760°C) where VOCs are thermally destroyed.
  • After oxidation, the clean gases pass through another ceramic-filled canister, capturing and storing heat for preheating the next gases.
  • Every 90 seconds, the airflow is reversed to continuously recover heat efficiently.

In stricter regions like Europe and Australia, a third canister prevents VOC spikes during flow reversals.
