Varitherm® diffusers feature an architecturally appealing solid plaque design and high performance control linkage. The plaque can be opened to allow for easy access to temperature set-point dials, and minimum air flow adjustment.
Thermal actuators sense room air and adjust air flow into the space to satisfy the room load, requiring no wires for simple installation and maintenance.
