Compact solutions in one actuator: The EA-SZ EA-SZ 24/80/550 rack actuator offers several advantages: There are no protruding parts due to the toothed rack in one groove. This allows planning in any length. In addition, the SHE actuator has a long service life with minimal maintenance and high rigidity.

Expandable SHE actuator

The EA-SZ 24/80/550 actuator works very quietly and can be extended via a connecting shaft with a mechanical idler. Thus, it is also ideal for use with large window elements or rooflight dome systems. If required, the actuator can be extended by means of a rack idler and a connecting shaft (synchronous operation for a more stable opening of large elements).

Advantages at a glance:

  • Effective energy consumption
  • Maximum stroke utilization
  • Synchro insert with idler mechanism and connecting shaft
  • Compact solutions through internal rack
  • High rigidity
  • Long service life with minimal maintenanc
  • Available as 24 volt and 230 volt versions

Under the Construction Products Regulations (CPR) it is a legal requirement to use only certified products for smoke ventilation. It is the responsibility of the installer to ensure installations meet the relevant standards. For more information see SCS Group’s Technical Bulletin.
