Cost Savings
One of the most significant benefits of opting for a refurbished RTO is the substantial cost savings. Refurbished systems can save you 40% or more in capital costs compared to purchasing new equipment. This makes it a budget-friendly option without compromising on performance or reliability. By choosing a refurbished RTO, you can allocate your budget to other critical areas of your operation, enhancing overall productivity and profitability.
Reduced Delivery Time
Choosing a refurbished RTO from Kono Kogs can significantly reduce delivery time compared to a new system. Our experienced team implements all system upgrades quickly with 90% of work accomplished under our roof. The result? A nearly new system allowing you to be online quickly, whether replacing your less efficient oxidizer on your current process, or a system to serve your expansion plans.
High Performance and Long-Term Reliability
Our refurbished RTOs start with the best-built system, and are meticulously restored to meet or exceed original performance standards. We ensure that all critical components are updated or replaced, providing you with a system that operates efficiently and reliably. Each refurbished unit undergoes rigorous testing and quality checks to ensure it meets our high standards, giving you peace of mind and confidence in your investment.
Longevity
With proper maintenance, a refurbished RTO can offer decades-long performance, comparable to new units. This longevity makes them a wise investment for long-term emission control. By choosing a refurbished RTO, you gain reliable performance for decades at a significantly reduced capital investment, along with energy efficiency and PLC controls/connectivity rivaling new equipment.
Environmental Benefits
RTOs are already the most efficient thermal oxidizer choice with very high VOC/HAP destruction efficiency. But refurbishing existing RTOs goes above and beyond when considering the positive environmental impact. One unique aspect offered by refurbished oxidizer systems is a significant reduction in Greenhouse Gas (GHG) emissions, as compared to a new oxidizer system.
While we rebuild and upgrade every sub-system on our refurbished oxidizer systems, the main body of the unit is mostly retained. Re-use of the main body- a structural metal base and a metal shell with internal insulation- eliminates multiple tons of GHG emitted for the virgin manufacture of this steel and insulating material. Scope 1, 2 & 3 emissions are a common way to quantify the benefits of reduce, re-use, recycle initiatives. Re-use of the main long-life components of an RTO provides an excellent net reduction of GHG emissions. Securing a nearly new oxidizer system to destroy VOC/HAPs while also reducing GHG emissions is a win-win for our clients and the environment.
Greenhouse Gas (GHG) Emission Savings with Refurbished Oxidizers

In steel and insulation re-use alone the average size (25,000 scfm) refurbished RTO provides a credit of 67 metric tons of CO2 emissions compared to a new RTO system.
Here's how the savings in material production breaks down when you buy a refurbished regenerative thermal oxidizer:
- Steel Production = 1.4-1.85 metric tons of CO2 emissions/ton of steel produced
- Ceramic Fiber Insulation Production = 1.2 – 1.7 metric tons CO2 per ton of insulation produced
- Ceramic Media = 0.5- 1.0 metric tons of CO2 per ton of ceramic media produced
Advantages of Buying a Refurbished RTO from Kono Kogs, Inc.
From start to finish, incorporating a refurbished regenerative thermal oxidizer from Kono Kogs provides the needed technological know-how, the extra support and record of quality that you should expect when seeking a custom emission control system.
Advanced Technology Integration
Our refurbishment process includes integrating the latest technological advancements. This means your refurbished RTO benefits from modern PLC technology, improved ceramic media designs, and enhanced heat recovery systems. Also, each OEM design has weak links that we are aware of from our nearly 30 years of rebuilding these systems. This unique knowledge allows us to upgrade components and controls to leverage the best parts of any OEM's systems. Our new RTO systems have their innovative design drawn from this hands-on knowledge/experience. These upgrades can lead to better energy efficiency and operational control. By incorporating state-of-the-art technology, we ensure that your refurbished RTO is equipped to handle the demands of modern industrial processes, providing superior performance and reliability.
Customization and Flexibility
Our refurbished RTOs can be customized to meet your specific needs, ensuring optimal performance for your particular industrial process. Our experience allows us to reconfigure an existing system to customize it for your particular process conditions. This unlocks our world's largest inventory for use in almost all emission control applications.
Comprehensive Support = Maximum Uptime

Refurbished Regenerative Thermal Oxidizers FAQs
Get quick answers to common questions regarding refurbished RTOs
Please check our RTO Inventory...Quality-built refurbished regenerative thermal oxidizer (RTO) systems have a long life, can save 40% vs. new units, and have performance and parts warranties comparable to new systems.
Yes. It is normally a simple conversion.
In most cases, yes. But proper evaluation is recommended to establish that no potential catalyst poisons or masking agents are present in your airstream.
Our experience is that regenerative thermal oxidizer (RTOs) systems less than 20 years old are good candidates for rebuild/repair/upgrade rather than for RTO replacement. Replacement costs including removal of existing, capital cost of a replacement system and shipping, ductwork, mechanical assembly, etc. add up quickly making it more cost effective to repair the system, upgrade the PLC, and/or add energy saving updates. Thermal recuperative oxidizer systems on the other hand usually are not cost effective to repair for long term use, but simple repairs may help limp these systems along until a replacement can be budgeted for. Catalytic recuperative oxidizers can be repaired, but the cost of catalyst replacement may justify replacement of the system if the catalyst has a history of contaminating quickly. Contact us and we can visit to make an evaluation. We want long term relationships with our customers so we provide our best evaluation of the total cost of ownership of each option so you can make an objective decision.
This is a common concern. Will the buyer be left with only promises, or will Kono Kogs provide robust support after the purchase and commissioning of the oxidizer?
