  • In-house lab analysis of catalytic oxidizer catalyst and carbon media

Catalyst and carbon testing

Dürr has a dedicated in-house testing lab for examining catalyst and carbon. Our testing services verify that catalytic oxidizer and carbon adsorption systems are able to deliver environmental compliance.


Your entire operation can depend on the performance of your VOC control system. Oxidizer catalyst testing ensures your catalytic oxidizer is ready to do its job. 

Dürr brings you the benefits of more than 30 years of experience providing environmental compliance solutions worldwide. We’re specialists in advanced catalyst formulations and thermal oxidation technologies, as well as oxidizer media testing. We know your equipment. We know the chemistry. And we know your industry.

When your catalyst or carbon needs replacement, turn to Dürr. We work with your staff to determine the best solution for your specific application. Our catalytic oxidizer media testing will determine how much and what type you will need. And if necessary, we can retrofit your unit to accept the new catalyst.

Dürr catalysts achieve conversion efficiencies greater than 99% in most applications - well above regulatory requirements. Our catalysts also help get you into compliance and ensure you stay in compliance longer.

Testing services

Routine oxidizer catalyst testing and carbon testing are cost-effective ways to ensure uninterrupted operation of your oxidizer and carbon adsorption system. Routine testing also helps document system performance. When coupled with an annual preventive maintenance check, oxidizer media testing and carbon adsorption testing can verify that a unit is in compliance. Many government environmental regulators now accept this as validation your system is meeting performance requirements. This approach is much less expensive than costly stack tests.

Dürr is the only oxidizer supplier with its own on-site testing laboratory. We provide the complete range of catalyst testing services you need. We recommend annual oxidizer media testing to confirm activity, surface area, and contamination.
