TRITON™ Regenerative Thermal Oxidizer
Our Highest Performing VOC Abatement Solution
The TRITON™ Regenerative Thermal Oxidizer by Alliance Corporation represents the finest Regenerative Thermal Oxidizer available and our highest performance product.
The TRITON™ fundamentally differs from the rest of the pack in that the TRITON™ includes 3 heat exchange beds in contrast to the 2-Bed design Regenerative Thermal Oxidizers emphasized by other manufacturers. The reason 2-Bed designs are popular is simple: 2-Bed Regenerative Thermal Oxidizers require less materials and are inherently less expensive to build.
TRITON™ Details and Specifications
2-Bed Regenerative Thermal Oxidizers are perfectly suitable for many applications which is the reason that Alliance Corporation also offers 2-Bed Regenerative Thermal Oxidizers with our KRONUS™ product-line; however, where maximum performance is required, there are some drawbacks to consider for Regenerative Thermal Oxidizers with less than 3 beds.
The TRITON™ Regenerative Thermal Oxidizer by Alliance Corporation offers the benefits of maximum destruction efficiency, high heat recovery, and process application flexibility of regenerative thermal oxidization designed in an economical modular package to create an outstanding overall value in high performance emissions control equipment. The TRITON™ is designed with integral valves to direct the flow through the heat exchange beds incorporated into the oxidizer body. The integral valves minimize the oxidizer footprint. The entire oxidizer is housed in a single* compact box. This integral valve feature eliminates the transition ducts often associated with conventional Regenerative Thermal Oxidizer designs and further simplifies the field installation.
*TRITON™ Regenerative Thermal Oxidizer systems 12,000 SCFM and below are built as single contiguous pre-assembled modules. Larger TRITON™ Regenerative Thermal Oxidizer systems are comprised of multiple modules to accommodate conventional shipping. Each module includes a heat exchange bed, combustion chamber section, inlet and exhaust valves, burner, combustion air and gas train as appropriate. These modules are completely pre-assembled and shipped ready for installation.
- No Vacuum Spikes
Regenerative Thermal Oxidizers are susceptible to vacuum spikes. By definition, it is the nature of all Regenerative Thermal Oxidizers to change the flow direction through the beds at regular intervals to exchange heat. 2-Bed Regenerative Thermal Oxidizers must internally reverse the flow between the two beds when the flow direction is changed. While most 2-Bed Regenerative Thermal Oxidizers attempt to reverse the flow reversal as quickly as possible, there is still a period of approximately one second when both inlet and exhaust ports to each bed are open and the untreated process is able to bypass the Regenerative Thermal Oxidizer. During this bypass period, the pressure drop of the beds is momentarily removed and the process fan which produces a constant differential pressure transfers the excess energy from the momentary loss of back pressure to the inlet duct-work in the form of a vacuum spike. While it is often overlooked when selecting a Regenerative Thermal Oxidizer, the magnitude of the vacuum spike can be quite severe and wreak havoc on fragile processes such as web handling, semiconductor, etc.
TRITON™ Regenerative Thermal Oxidizers differ with the availability of a 3rd bed. TRITON™ Regenerative Thermal Oxidizers do not reverse the flow internally, rather the flow is rotated through the beds. The rotation avoids opening the inlet and exhaust ports simultaneously. Therefore, the process is never bypassed and thus no appreciable vacuum spikes are created.
It takes 3 times longer to do anything in the field than is does in the shop. Therefore, all Alliance Corporation Regenerative Thermal Oxidizers are completely factory pre-assembled. This includes mechanical assembly of all components, plumbing and electrical. Every Alliance Regenerative Thermal Oxidizer undergoes extensive factory testing, control systems check out and calibration prior to shipment. The factory pre-assembly reduces the installation effort and maximizes quality control over the finished product. The factory testing ensures a smooth startup. A typical installation can be completed in a day. A typical startup can be completed in as little as 2 days on-site, including personnel training.
- 99%+ VOC Destruction Efficiency
VOC destruction is the measure by which an oxidizer destroys Volatile Organic Compounds (VOCs) exhausted from the process. VOC destruction is the method to determine the caliber of an oxidizer. By the same means that a 2-Bed Regenerative Thermal Oxidizer bypasses the beds and generates vacuum spikes during flow reversals, untreated process is also allowed to bypass the Regenerative Thermal Oxidizer. The bypass flow combined with the entrained volume of the plenum and heat exchange media void space allows a significant spike of VOCs to escape to atmosphere untreated each time the flow is reversed. This VOC spike limits the 2-bed VOC destruction efficiency to around 95%2. Some applications can tolerate the lower VOC destruction efficiency of 2-Bed Regenerative Thermal Oxidizers; however, it is becoming increasingly common to require greater VOC destruction. In addition to VOC destruction, opacity is another factor to consider for processes containing condensable solvents, as when the VOC spike escapes it may be possible to see a puff of smoke leave the exhaust stack. To offset the VOC spike of 2-Bed Regenerative Thermal Oxidizers, some manufacturers utilize a downstream chamber with a diversion valve to capture the VOC spike. The captured VOC spike is then recycled back to the Regenerative Thermal Oxidizer inlet. Downstream chambers are limited since VOC spikes must be captured in motion. The VOC spikes are partially lost to the exhaust flow due to eddy currents, varying velocities, capture valve timing, etc. A capture chamber also adds back pressure to a 2-Bed Regenerative Thermal Oxidizer which requires increased process fan horsepower.
Just as the TRITON™ Regenerative Thermal Oxidizer avoids generating vacuum spikes by rotating the flow through the beds, the TRITON™ Regenerative Thermal Oxidizer also avoids VOC spikes. Additionally, the entrained volume is automatically contained in the off-line bed and is recycled back to the oxidizer inlet stream. TRITON™ Regenerative Thermal Oxidizers are designed and guaranteed to destroy 99.0%** of the VOCs present in the process inlet stream to the Regenerative Thermal Oxidizer. There are instances where TRITON™ Regenerative Thermal Oxidizers have achieved 99.6% VOC destruction in the field.
TRITON™ 2-Bed Regenerative Thermal Oxidizers can be tuned by Alliance Corporation to enhance the VOC destruction up to a guaranteed to 98%**.
** If all of the Performance Conditions defined in the Proposal are satisfied, then the Regenerative Thermal Oxidizer will reduce the concentration of hydrocarbons measured at the exhaust as compared to the concentration of the inlet to the Regenerative Thermal Oxidizer by an average of greater than the stated percentage or down to 25 Parts Per Million Volume (PPMV) measured as C1 in the exhaust from the Regenerative Thermal Oxidizer. Please refer to the standard terms and conditions included with the Proposal for further detail.
Our credo is that it takes 3 times longer to do anything in the field than is does in the shop.

This includes mechanical assembly of all components and plumbing, and wiring of control cabinets, junction boxes and components. Every Alliance Regenerative Thermal Oxidizer undergoes extensive factory testing, control systems check out and calibration prior to shipment. The factory pre-assembly reduces the installation effort and maximizes quality control over the finished product. The factory testing ensures a smooth startup. A typical installation can be completed in less than 2 days. A typical startup can be completed in as little as 2 days on-site, including personnel training.
- State of the Art Controls
At first glance, many Regenerative Thermal Oxidizers can seem similar in that they are all basically insulated boxes containing some type of ceramic media and a means for switching the flow direction. While we can and will make the case that the design, materials, components and execution of our Regenerative Thermal Oxidizers is superior to the competition, it is controls that is one of the greatest areas of difference that sets Alliance Corporation apart from the rest of the Regenerative Thermal Oxidizer manufacturers.
Alliance Regenerative Thermal Oxidizers feature state-of-the-art controls with detailed proven software that is self-diagnosing and correcting. The software is the result of years of field experience. The software contains complex algorithms to wring out the maximum VOC destruction and thermal efficiency. The software and graphic operator interface provides the end user with unmatched intuitive and simple operation. We guarantee the performance of the software for the life* of the Regenerative Thermal Oxidizer.
One of the keys to our successful control systems are VPNs included as a standard feature with each Regenerative Thermal Oxidizer. The VPNs allows real time monitoring of our Regenerative Thermal Oxidizers. Combined with the data collected by our telemetry software, these tools enable Alliance Corporation to provide unparalleled support.
*The lifetime guarantee requires a working DHCP internet connection to the VPN. The lifetime guarantee is for the proper functionality of the PLC program for all aspects of the Regenerative Thermal Oxidizer operation for the scope at the time commissioning. In the event of future process scope changes after commissioning that require programming, the programming may be billed on a time and material basis.
Every Alliance Regenerative Thermal Oxidizer is equipped with a Programmable Logic Controller (PLC) equipped with an Ethernet port that is attached to a VPN. The VPN allows monitoring of the PLC and HMI code. The VPN allows us to diagnose and troubleshoot directly in real time so that we can provide quick support. With the VPN in place, we are able to provide extended hour support for the maximum up-time of the system.
The PLC performs both control of the Regenerative Thermal Oxidizer and data logging. Every event, warning and fault is time and date stamped and stored in the PLC memory. Key process variables are recorded at regular intervals and stacked into the PLC memory. Alliance has developed software to retrieve this data from the PLC memory via a VPN. With the operation history, we are able to ensure optimal performance and up time. Please contact us for a live demonstration. We will come to your offices and connect to an operating Regenerative Thermal Oxidizer with our smart phones. We are confident that you will be impressed.
- Top Quality Components and Materials
Alliance Corporation has learned through experience of servicing and repairing oxidizers built by others that there is no benefit to cutting corners on materials and components. We have deliberately chosen to use the most robust materials and highest quality components available. You might consider that the quality of our components, craftsmanship and attention to detail would lead to higher prices for our equipment; however, just the opposite is true. We make up the difference in warranty savings. Alliance Corporation equipment has a proven track record of extreme reliability, and as such, our warranty expenses are negligible. Therefore, we are able to reflect warranty overhead savings in our up-front equipment pricing which you will find is among the most competitive in the industry.
Some examples of quality that set Alliance Corporation apart:
Alliance Corporation fabricates all standard oxidizers out of 1/4" thick carbon steel plate. Alliance also fabricates oxidizers out of stainless steel, AL6-XN® when required for special processes.
Alliance Corporation manufactures robust 2-way poppet valves for the inlet and exhaust of each bed. The valve seats are machined from solid steel. The valve disk is a steel plate disk sandwiched between a machined steel hub with a bolted and welded end cap. The disk assembly is threaded on to solid stainless steel shaft and locked at three points. The shafts are supported and housed in a purged pipe with self-aligning guide bearings at top and bottom.
Alliance Corporation poppet valves are automated by specially built actuators with extended internal pneumatic cushions to reliably slow down the disk to ensure gentle quiet contact with the seat. The actuators are fitted with mufflers to suppress pneumatic noise. Our actuators are built to endure decades of continuous use with no appreciable wear.
The interior of the combustion chamber and heat exchange beds are insulated with 8” thick SuperWool® compressed fiber modules stud welded in place. On high temperature applications, the interior of the inlet and exhaust poppet valve manifolds are insulated and cladded. There is no external insulation.
Alliance Corporation uses structured heat exchange media made of industrial porcelain. Structured media has greater thermal efficiency and a lower pressure drop which allows for smaller, more efficient beds. Structured media never requires additional material or leveling. Structured media will last the lifetime of the Regenerative Thermal Oxidizer on particulate and silicon free processes.
Alliance Corporation Regenerative Thermal Oxidizers include a ladder and handrails for easy, safe access to all components. All ladders and handrails are powder coated to ensure a maintenance free durable finish.
The controls, including the Variable Frequency Drive (VFD), are housed in a single climate controlled enclosure mounted on the Regenerative Thermal Oxidizer and factory wired to all of the components.d to all of the components.
All Alliance equipment is chemically etched, epoxy primed and finish painted with urethane.
- Easy Installation
All Alliance Corporation Regenerative Thermal Oxidizers ship pre-assembled and ready to install. Typically our supervision is not required for installation. If your firm is capable of offloading the shipment when it arrives and setting the equipment in place, you will have completed most of the installation. All of our Regenerative Thermal Oxidizers can be offloaded with a forklift; however, welded lifting lugs are also provided for a crane, if needed. There is no field welding or painting required. All hardware, gaskets and vibration isolators are provided. Generally, all that remains is connecting the utilities and duct-work. Alliance Corporation will provide the remote support at no charge and of course, Alliance will provide complete turnkey services should you prefer; however, our goal is to provide equipment completely pre-assembled so the installation is quick and simple and overall project costs are minimized.
