What To Look For In A Used Replacement RTO

Buying a Used RTO – What Questions Should Be Asked?


A Regenerative Thermal Oxidizer (often referred to as RTO) destroys pollutants like Hazardous Air Pollutants (HAPs), Volatile Organic Compounds (VOCs), and odorous emissions that are often discharged during industrial processes.


RTOs are the technology of choice today because they achieve the highest VOC destruction with the lowest operating cost, and highest reliability relative to other oxidizer technologies. All oxidizer technologies achieve VOC destruction by exposing pollutant-containing air to a high temperature, for a set period of time, in a turbulent flow path.  Time, temperature and turbulence- Three T’s-  are critical and co-dependent factors that determine oxidizer performance. Regenerative thermal oxidizer systems utilize a special heat recovery method – regeneration- that has proven to be the most cost effective approach for typical industrial applications.


When you’ve got a need for a cost-effective replacement Regenerative Thermal Oxidizer, there are a few key questions to consider. Konokogs carries a large range of RTO brands and types, from MEGTEC, Tann, Adwest, and more. From knowing your exhaust airstream needs to which types of VOCs and emissions will be removed, these are a few of the criteria the Konokogs team will be able to answer to make sure your Used RTO is optimized for your specific needs.


What to Look for in a Regenerative Thermal Oxidizer (RTO):

  • Is the RTO optimized for my exhaust airstream?
    • RTO’s typically treat airstreams with a 0-10% Lower Explosive Limit (LEL)
    • RTO systems can handle 25% Lower Explosive Limit (LEL) airstreams
      • Hot gas bypass systems and other features may be needed
  • Is the ceramic media in the RTO optimized for:
    • maximum thermal efficiency
    • lowest pressure drop
    • Ability to handle organic/inorganic particulates
  • Does the RTO main fan utilize a variable frequency drives (VFD)?
    • Important for volume turn-down and idle operation
  • Is the RTO skid mounted with little welding required in the field?
    • Ease of installation will result in lower turnkey cost
  • Does the RTO have telemetry (Ethernet) for remote troubleshooting access?
    • Remote troubleshooting access  can reduce service visit frequency
  • Are visible emissions eliminated by this RTO?
    • A puff capture feature may be required to eliminate visible emissions
  • Is the RTO burner designed to maintain temperature during full flow, no VOC conditions?
  • Would a fuel gas injection system be a wise choice for this application?
    • Fuel injection can provide significant fuel savings
  • Is there a used RTO system available with the features needed?
    • Quality-built, used regenerative thermal oxidizer (RTO) systems have long life, can save 40-60% vs. new units, and offer performance and parts warranties

Other Used RTO Considerations:

  • Is there a risk of ceramic media plugging due to condensing VOCs?
    • A Bake-out feature can address organic build-up
  • Does the RTO have to address potentially corrosive emissions/halogens?
    • Special materials of construction may be required
  • Would an induced draft fan be a better choice than a forced draft fan?
  • Is there sufficient heat in the RTO exhaust (>250F) to consider secondary heat recovery
  • Is the process sensitive to pressure pulses possible with poppet valve?
  • Do local codes require Low NOX operation?
    • Low NOx burners can be retrofit for these applications.

Kono Kogs Removes + Delivers Regenerative Thermal Oxidizer (RTO) in 2 Days

A core service that sets Kono Kogs apart from other RTO resellers is our ability to not only replace old or outdated oxidizers – we also offer removal of the existing oxidizer! When the timing of shipping and installation don’t align with your current operational schedule, we can help. We can prepare your RTO for outdoor storage until you’re ready to install. We also offer RTO shipping to anywhere in the United States and Canada – just contact us and let us know the details of your situation.


See below for details on an RTO removal that was done extremely quickly and with minimal downtime in the middle of winter – in just 2 days!

Fast RTO Removal and Delivery in 2 Days

During the last week of December in 2018, Kono Kogs removed this MEGTEC Clean Switch 25,000 RTO and delivered it as a Kono Kogs Warranty-Backed Used RTO to a customer the very next day. After shipment, the Used RTO was prepped for outdoor winter storage to be installed several months later. After calculating the best and most cost-effective shipping options, it was determined that a direct shipment option was the most cost-effective approach to handling this particular RTO. Due to its extremely heavy weight (the heaviest piece of the machine was 77,000 lbs), this RTO required special trailers and escorts during transportation. By combing the various shipments and rigging needs into one direct shipment, Kono Kogs was able to save the customer both time and money.


This RTO was the 4th Used RTO this customer has purchased from Kono Kogs. We are proud that our customers feel a sense of trust when working with Kono Kogs, and taking care of our customers needs while providing cost-effective options is what sets us apart from other companies.


Kono Kogs has been buying, refurbishing, selling, servicing, and guaranteeing the performance of our used thermal and regenerative thermal oxidizer systems for over 22 years.
