Shut-off dampers

Shut-off dampers are supplied pre-wired to the control system and factory-tested. The dampers are installed in ventilation ducts and ensure controlled shut-off of the airflow.

The damper actuators have a protection rating of IP54. For outdoor installation, protective enclosures with IP56 rating can be selected for additional protection against wind and weather conditions.

Shut-off dampers are available:

• as standard shut-off dampers
• with spring return, typically used in connection with water after-heating element (supplied as one spring-return damper in combination with one standard shut-off damper)

All variants are supplied ready for installation and integrated into the unit’s control system.
