秒速赛车开户Safe escape routes for people and safe entry routes for firefighters is the key points of a building's safety concept.
The basis of the fire safety concepts in Europe is the standard 120101 part 6. This standard is separated into application classes, A to F.
Class A to E describes self-rescue with (partly) simultaneous firefighting. Here, the focus is on self-rescue and the maximum differential pressure must be below 50 Pa.
Class F addresses firefighting. Here, the permissible differential pressures must be above 50 Pa.
Mechanical systems cannot usually switch between different operating pressures. (max 50Pa/min50Pa).
For this reason, electronically controlled overpressure systems bring a new dimension to fire protection. With a simple switch, the fire brigades can increase the system to maximum performance, which usually eliminates the need for mobile fans. This means that electronic overpressure systems not only support rescue routes, but also provide additional protection to firefighters against flue gases at high temperatures/pressures. It will provide clear visibility and usually make it possible to quickly reach the cause of the fire.
Systemair is the leading company in differential pressure systems with control of EC-motor technology or frequency inverter control technology. An airtight building places higher demands on the systems reaction time.
