Update: Split System DX-DOAS Now Listed in AHRI Directory

| Aug 2026

In our previous communication, we shared that we were temporarily turning off the split system DX-DOAS option in ECat while we worked to meet program timelines. As communicated, this change was implemented with the release of Version 6.365.0.

We’re pleased to share an important update: AAON is now fully certified in the AHRI 920 program, and ratings for both our split system and rooftop unit DX-DOAS products are now listed in the AHRI Directory.

With these certifications and ratings now available, we have completed the step we outlined in our previous communication and can move forward with the next phase of the DX-DOAS offering.

With the upcoming ECat release, the split system DX-DOAS option will be selectable again for ordering.

Please contact your regional sales manager or Applications Department if you have any questions.
