A Peer Reviewer Said It. The Fluid Flow Proves It.

An independent review concluded the Diamond-Shaped Actuator has real potential to help mitigate climate change. This video shows exactly why — walking through the fluid flow at each stage of operation, so you can see how it works, not just take someone’s word for it.

Induction units provide heating and cooling for offices in many commercial buildings. This video explains how these systems operate and highlights two major BAS retrofit errors that we have encountered in the field. While these issues can significantly impact performance, the original induction unit design is also inherently energy inefficient. That broader design issue, along with practical methods for improving efficiency, will be addressed in a separate video.
