Varitherm Series
Varitherm Series

The Price Varitherm® is a thermally powered, self-modulating diffuser that features a specialized linkage design for optimal zone temperature control in a stand-alone package. The Varitherm® VPD-HC is available for heating and cooling modes with an automatic heating/cooling changeover, and the Varitherm® VPD-C is available for cooling only applications.

Prodigy Series
Prodigy Series

The Price Prodigy® diffuser features an architecturally pleasing faceplate design and high performance inner cone. A DDC controller utilizes advanced adaptive control algorithms and a high torque motor to modulate air flow and maintain constant room temperatures. The Prodigy® Series allows for true VAV control in cooling and heating cycles. Reheat, control of up to 5 drones, building automation, and system pressure control are all possible with the Prodigy® Series.

Pressure Control Valve
Pressure Control Valve

The Price PCV is a pressure control valve for use upstream of diffusers. A static pressure sensor downstream of the PCV provides a signal for the valve to control, ensuring that the static pressure in the duct does not exceed "The Design Pressure". The PCV can be used in either a by-pass configuration where excessive air is by-passed into the ceiling space, or where the PCV controls the pressure in the duct by dampening the upstream supply.


VAV Accessories

Price offers additional accessories for both the Prodigy® and Varitherm® diffusers. The PRC is a mechanical pressure relief collar suited for Price VAV diffusers, which bleeds air into the ceiling space when the inlet static pressure exceeds .25 in. w.g. The PPM is a power module designed to allow for up to 30 Prodigy® diffusers to be connected in series with minimal electrical wiring.
