Since 1978, Acutherm has been dedicated to creating more comfortable and energy-efficient building environments. Our VAV diffuser systems have proven to be the simple, reliable and economical solution for individual temperature control.

In 2017, Acutherm joined Price Industries to elevate how we bring our products to market. This new relationship allows us expanded access to technology and product development resources to create better solutions for our customers.

How it works

Each VAV diffuser is an independent zone of variable air volume control with individual room thermostats and built-in modulating dampers for varying the air volume. The dampers are continuously adjusting to vary the volume of air flow (warm or cold) into the room, in response to room temperature. Unlike fixed opening diffusers, which dump cold air on occupants at low volumes, the variable air opening within all of our diffuser models creates high discharge air velocity even at lower supply volumes. This maintains the Coanda effect where high velocity air hugs an adjacent surface, holding cold air up to the ceiling and prevents dumping.

The benefits

Personal comfort and control is possible. Our diffusers act as an individual VAV zone of control, providing temperature settings maintained within 1½°F/0.9°C. No dumping, high discharge velocity, persistent throws, better room air movement and uniform temperature distribution define an optimized environment.

Unlike a fixed-grill diffuser, each of our Acutherm VAV diffusers are a self-contained zone of control with individual thermostat and built-in VAV mechanisms. The system is accessible from the room-side, unlike other devices, which require above-ceiling access for ongoing maintenance and calibration. Both on a first installed cost and ongoing operational basis, our VAV diffusers are the most economical way to improve comfort and energy savings.

Energy Savings
As U.S. Green Building Council members, Acutherm is proud to produce low pressure, energy-efficient, VAV diffuser systems that prevent overcooling and overheating – resulting in 10%-31%  energy savings, when compared to other HVAC systems.

Sustainability and Integration
Sustainable buildings are designed to be environmentally responsible and resource-efficient throughout their lifecycle. For sustaining long-term usefulness, our VAV diffuser systems are modular and adaptable to layout and programming changes, while influencing up to 21 LEED® credits.

Key Contacts


Vice President, Managing Director


During my tenure with the company since 1995, where I have served as President and CEO (2002-2017) and Vice President/Managing Director, I have found the increasing global demand for our products to be quite rewarding.


Director, Engineering


I first worked for Acutherm part-time in the 1980s in the Direct Mail Marketing department.  I returned to Acutherm in 2003 as a project engineer.

I appreciate a well-designed and well-built mechanism and our TF diffuser is a master example. As a mechanical engineer I love that we can provide individual comfort control with a purely mechanical device.  Expanding our line of products has also been an exciting challenge, balancing sophisticated controls that interface with building automation networks with the clean powerful designs that have underpinned our success. Whether it is a simple system or a complex network, it is great to work with a product that has such a direct effect on individuals by helping people be more comfortable.


Associate Product Manager


My vision for my professional future, and for the future of Acutherm, is continuing to develop and advance technology in building design for improved efficiency, comfort and control.

In my previous roles as a Design Engineer and Engineering Manager in Stratified Air Systems at Price Industries, I oversaw product development, manufacturing implementation, tooling design, certification testing and performance testing for a variety of project applications across the continent. This experience is a perfect fit for how I contribute to solving complex design problems for Acutherm’s clients.
