TRITON III Series Regenerative Thermal Oxidizer

TRITON III-Series Regenerative Thermal Oxidizers are the traditional three-tower (or multiple tower) designed RTO. While these systems require somewhat higher initial cost, their benefits are realized by being able to achieve up to 99.9% removal efficiency. In some applications, this level of removal efficiency may be required to meet permitting requirement, corporate emission goals, or if odorous compounds are a concern, the TRITON III-Series Regenerative Thermal Oxidizer is the perfect solution.

  • For more than 42 years, Catalytic Products International has focused its efforts on supplying our customers with the worlds best air pollution control solutions.  In today’s environmental climate, just about any source may be a target for add-on air pollution control equipment.   The TRITON-Series RTO is the answer to environmental agencies trends to regulate even the lowest emitters of air pollution causing volatile organic compounds (VOC’s).

    The TRITON III-Series RTO is a Three-Tower System, meaning there are at least three regenerator towers holding the specialized ceramic media.  In some larger volume applications, additional towers may be included.  The media is chemically and thermally stable designed to provide 85% to 97% thermal rate efficiency (TRE).   Since each TRITON-RTO is custom designed to your exact needs, we can choose the ceramic media system and the associated % TRE to maximize your process conditions and provide the most efficient operation.

    You can be assured that your TRITON-Series RTO will be designed with the industry leading design features especially suited to your needs.   Proprietary designed Posi-Seal Valves matched to our duct-under Even-Flo Plenums minimize entrained volumes and accurately seat valves for the highest VOC removal efficiency.  Structurally sound cold face supports provide the long equipment life and uptime reliability demanded in today’s air pollution control systems.  Control features such as our Thermal Control Logic maximizes the thermal efficiency based on the exact conditions presented by your process.

    These systems are easy to install, provide very high removal efficiency, and offer very low operating cost.  With thoughtful engineering and continuous advancement in design, the TRITON-Series RTO can be counted on to provide years of reliable service.

    Thermal treatment of VOC’s and other air pollutants works by a simple reaction of the harmful air pollutants with oxygen and heat.  In this environment the VOC’s are converted to harmless inert byproducts, water vapor (H2O), and usable heat.  These harmless by-products are released to atmosphere or use an energy recovery technique to further lower the operational costs.

    TRITON-Series RTO’s are considered among the world’s most advanced recuperative thermal oxidation systems.  These specially designed and proven systems combine the basic principles of time, temperature, and turbulence – matched to industry leading construction and design features.  All resulting in exceptional performance, substantially reduced operating costs, and industry-leading reliability.


    The TRITON-Series Regenerative Thermal Oxidizer process begins with the touch of a button, which activates the system’s PLC-based Temperature Safety System (TSS).  The TSS control system automatically retrieves media temperatures, selects the hottest bed for damper positioning, opens the fresh air purge/idle damper, energizes the booster fan, purges the system with fresh air, ignites the burner, cycles the valves, and gradually brings the system up to the correct operating temperature. The TSS also monitors the temperature in the regenerators, combustion chamber in three places, and in the valve assembly’s inlet and outlet. This helps safeguard the system from extreme temperature fluctuations that cause thermal stress and overall system fatigue.

    As soon as the required operating temperature is reached, the TSS enables the process lines to feed into the oxidizer, or holds the system in idle mode until production is ready. When production is ready the fresh air purge damper closes and one or more of the diverting dampers open to draw the volatile organic compounds (VOC’s) off of the process lines.

    A booster fan draws one or more VOC-laden exhaust from your process lines into the system. From there, VOC’s are directed into one of the systems regenerators (an internally insulated vessel containing ceramic media). The contaminated gases are passed through the first regenerator where energy is transferred from the ceramic media to the gas in order to elevate the temperature. This elevated temperature approaches the ignition level for most solvents and then is directed from the ceramic bed into the combustion chamber. As the stream exits the ceramic bed and travels through the internally lined combustion chamber minimal heat is added to ensure a proper oxidation temperature and a designed dwell time is maintained for the ultimate destruction of the streams VOC’s.  The oxidized gases are then directed to the second regenerator to absorb the heat energy.  As the ceramic media loads with sufficient heat, the Posi-Seal Valves switch, and the gases are reversed through the system where the second regenerator bed continues the energy transfer and oxidation cycle before being released to the atmosphere.

    While the first and second regenerators are exchanging energy, the third regenerator is being purged with clean air.  This purging of valves and regenerator prevent un-treated VOC’s from ever reaching the atmosphere and is the basis for TRITON III-Series Regenerative Thermal Oxidizer’s ability to reach +99.9% removal efficiency.  The purge air is internally recirculated back through the combustion chamber and over the exhausting regenerator tower before being release to atmosphere, or to auxiliary heating systems such as; secondary air to air recovery, air to water recovery, air to oil recovery, or directly back to the process in a closed loop direct recirculation process.

    Your process is now in compliance with all clean air regulations !!
