Actuators: Zitrón equips its dampers with the most reliable and precise actuators in the market, strong enough to guarantee accurate operation over many years. The different types of actuators are chosen in accordance with the customer’s requirements and can be electric, pneumatic or electro-hydraulic, with integrated control cabinet fitted in the ventilation system.
The actuator internal limit switches are used to control and stop the actuator when the damper is completely open or completely closed. Extra limit switches, torque switches, potentiometer, heater and other accessories can be included.
Actuator casings: In order to achieve an adequate thermal protection for the actuators, specially designed casings are provided, which ensure the actuator’s continuous operation, even in the most adverse conditions (250-400-600oC/ 1-2 hours). Zitrón provides actuators with a either a flexible (textile jacket) or rigid protection (ceramic case).
