<\/p>\n

A functioning smoke and heat extraction system is essential to remove dangerous smoke layers in the event of a fire and to keep escape routes passable. Electrical Window drives<\/a> They play a central role here: They open affected windows or skylights automatically and reliably \u2013 even under high load.<\/p>\n

In brief:<\/strong> In a smoke and heat exhaust system, the window actuators open the smoke vents in the event of fire \u2013 quickly, reliably and even against wind and snow load. That is why sufficient force, robust technology and regular maintenance matter for RWA actuators.<\/p>\n

<\/p>\n

<\/p>\n

High-quality actuators are more than just mechanics. They must meet clear safety standards and withstand a high number of load cycles. Our models achieve at least 10,000 double strokes under maximum load and are therefore ideally prepared for regular everyday use and emergencies.<\/p>\n

<\/p>\n

<\/p>\n

A coordinated combination of drive, control system, and sensors creates comprehensive smoke and heat exhaust ventilation (SHEV) solutions that offer planning reliability to tradespeople and construction companies. Thanks to our own stock in Hamburg, many common models can be delivered at short notice \u2013 a major advantage for time-critical projects.<\/p>\n

Frequently asked questions<\/h2>\n

<\/p>\n

<\/p>\n

What is the role of window actuators in a smoke and heat exhaust system?<\/h3>\n

<\/p>\n

<\/p>\n

In the event of fire, they open the assigned windows or rooflights automatically and reliably \u2013 even under high load \u2013 so that dangerous smoke layers can escape and escape routes remain passable.<\/p>\n

<\/p>\n

<\/p>\n

What requirements must a high-quality SHEV actuator meet?<\/h3>\n

<\/p>\n

<\/p>\n

It must meet the relevant safety standards and withstand a high number of load cycles. Vent Systems actuators achieve at least 10,000 double strokes under maximum load.<\/p>\n

<\/p>\n

<\/p>\n

Can SHEV actuators also be used for daily ventilation?<\/h3>\n

<\/p>\n

<\/p>\n

Yes. Actuators with a high cycle rating are designed for regular everyday use as well as for emergencies. What matters is a well-matched combination of actuator, control unit and sensors.<\/p>\n
