Open Air Damper Actuators
Siemens Engineering
Siemens Sensors
Damper Actuators provide control, either electronically or pneumatically, for a variety of HVAC applications, including: VAV Systems, Mixing Boxes, Central Fan Systems, Exhaust Dampers, Fire/Smoke Dampers. A basic rule of control valve sizing is: The higher the percentage of drop across the wide open valve in relation to the percentage of pressure drop through the line and process coil, the better the control. SymaroTM HVAC sensors record and transmit readings extremely quickly and accurately, providing an optimal basis for precise and therefore energy- and cost-efficient control of the entire HVAC plant.
