Pneumatic furnace damper drives may be more common, but electro-hydraulic actuators provide several advantages to the more traditional control scheme. One fossil-fired plant in Taiwan achieved more ...

Greenheck has introduced a round industrial control HVAC damper to accommodate higher velocities and pressure. Model HCDR-450 is rated for velocities up to 7000 fpm and pressure up to 30 in. wg, and ...

Description: The low-leakage insulated control damper features insulated airfoil blades, which offer great strength, produce minimal sound, provide sealing ability, and reduce static pressure loss. It ...

Equipment designers find that proportional control technology is ideal where precise performance is required in variable pressure or flow applications. Often perceived as more complicated than other ...
