Thermally Powered VAV Diffusers

Product Overview

 

Product Overview

With over two million installed worldwide, Acutherm Thermally Powered VAV Diffusers deliver outstanding air distribution with longer throws, more entrainment, even temperature distribution, higher ADPI and better ventilation effectiveness for projects ranging from education, healthcare and transportation. The Acutherm product line includes a selection of square and linear VAV diffusers.

Square Diffusers

Square diffusers by Acutherm offer outstanding air distribution. Unlike fixed opening diffusers used with VAV boxes, Therma-Fuser modules vary the discharge opening as they vary air volume, resulting in an almost constant discharge velocity, with better throw, higher room air movement and uniform temperature distribution. Acutherm offers a selection of models.

ST 2x2 Therma-Fuser™ VAV Diffuser
Stand Alone Square Therma-Fuser™ diffusers provide individual temperature control to precisely match comfort requirements of each space. Each Therma-Fuser diffuser is its own VAV zone, and thermostats, actuator and damper are built into the diffuser. Special features include:

TF 2x2 Therma-Fuser™ VAV Diffuser
The TF Therma-Fuser Diffuser is a widely specified, thermally-powered VAV diffuser. Over one million have been installed throughout the world. Special features of the system include:

TB 2x2 Therma-Fuser™ VAV Diffuser
Model TB Therma-Fuser diffusers are 24" x 24" ceiling diffusers with built-in temperature controls and VAV damper. The diffusers provide individual temperature control to precisely match the comfort requirements of each space. Each Therma-Fuser diffuser is its own VAV zone. The thermostats, actuator and damper are built into the diffuser. Special features:

LT 2x2 Therma-Fuser™ VAV Diffuser

The Model LT-HC Therma-Fuser diffuser is a nominal 24" x 24" (600 x 600mm) ceiling diffuser with built-in temperature controls. The LT-HC has four dampers that open and close to meter air flow (warm and cold) into the room in response to room temperature. The dampers are mechanically actuated by thermal element thermostats.Stand Alone Square Therma-Fuserâ„¢ diffusers provide individual temperature control to precisely match the comfort requirements of each space.

VA 2x2 Therma-Fuser™ VAV Diffuser

The Acutherm VA-HC Therma-Fuser VAV Module satisfies ASHRAE 62 requirements without wasteful over ventilation, regardless of thermal load.


Linear Slot Diffusers

Acutherm Linear Slot Diffusers have a slim profile and individual temperature control, with thermostat actuator and damper built into each diffuser. Like square diffusers, linear diffusers deliver outstanding air distribution, longer throws, more entrainment, even temperature distribution, higher ADPI and better ventilation effectiveness. Several models are available.

TL Linear Slot Therma-Fuser™ VAV Diffuser

Model TL Therma-Fuser diffusers are linear ceiling diffusers with built-in temperature controls and VAV damper. The damper blades open and close, metering airflow into the room in response to room temperature. The damper is mechanically positioned by a thermostat/actuator, that is both room thermostat and damper motor. Special features include:
