VAV Diffusers, Controls & Accessories
Acutherm’s VAV diffuser approach combines contemporary HVAC design with advanced control to deliver sustainable, efficient comfort. By creating small temperature-control zones, their diffusers improve air movement and comfort while supporting low-pressure, high-turndown air systems for energy savings.
Available in mechanical thermal actuation and digital electric actuation, Acutherm diffusers operate as simple, stand-alone devices when supplied with appropriate air temperatures and pressures—maintaining air circulation, minimizing stratification, and enabling high-performance system design.
