High Performance HVAC Laboratory

At Governair® and CES Group we have a long tradition of utilizing cutting edge technology to test, verify, and improve the performance of our equipment. As one of the first HVAC manufacturers to recognize the emerging emphasis on acoustical performance, We began conducting sound pressure and sound intensity testing in the 1980's and has been leading the pack in the arenas of HVAC system and acoustical performance and verification ever since.
Cabinet Vibration Study GraphIn 1994, we demonstrated our commitment to ingenuity and forward thinking through a sizable investment in a full-service, on-site acoustical and aerodynamic testing and research laboratory. This AMCA accredited facility is one of the largest dual reverberant chamber testing sites with airflow measurement capabilities in the world. It can accommodate production and R&D test scopes ranging from 500 to over 65,000 CFM.
Over the last two decades, laboratory personnel have garnered the highest reputation from customers and acoustical consultants across the country and have become recognized as a leading authority on aerodynamics and acoustics in the HVAC industry. The lab provides a wide range of unique services to our customers and venders including acoustical modeling, witnessed production testing, and robust performance and diagnostic analysis. The lab is also the site of rigorous, ongoing R&D test work designed to continually enhance and improve the entire CES Group product line.
The following list highlights some of the specific advantages that the Sound Lab on the campus of Governair in Oklahoma City affords our customers for critical performance applications:
