Fog in 29 seconds. Security in seconds.
Density® 900 is the high-capacity fog generator for safe rooms, ATM walls, tobacco shops and high-value reserves — pushing back intruders instantly with 900 m³ of dense fog protecting premises up to 900 m³ to zero visibility.
An alarm tells you it happened. Fog stops it happening.
A typical break-in is over in two to three minutes — long before anyone can respond. Security fog removes the one thing a thief needs: visibility.
Your alarm, a sensor or a panic input fires the unit.
After initial heat-up, the 900 floods the room with fog the moment it’s triggered — 900 m³ in just 29 seconds.
The intruder can’t see the goods, the exit, or their own hands.
Nothing to grab, nowhere to go. Most intruders abandon within seconds.
of theft attempts at fog-protected sites are stopped. A break-in is usually over in under two minutes — fog closes that gap in seconds, where an alarm only raises it.
