Automatic extinguishing systems for engines and electrical cabinets using the sensor tube are classified as automatic systems that are pre-engineered to sense and extinguish fire, and pre-engineered systems are known as systems with specific performance, inclusions and pre-operating systems, and these systems are characterized as cost-effective and environmentally friendly in terms of the amount of medium. The firefighter used in the process of extinguishing the fire in addition to its ease of maintenance, as the automatic extinguishing systems for engines and electrical cabinets sense the fire using a continuous thermal sensor tube that feels heat around its axis and then triggers the release of the extinguishing medium, and these systems are more flexible and effective in terms of performance and cost. In contrast to alternative mechanical and electronic systems, and its innovative design guarantees targeted security for high-risk areas such as electrical and mechanical equipment, which are difficult to protect in practice due to the difficulty of accessing dangerous places, as the flexibility of the sensor tube made it easy to install them inside the electrical panels and around their components directly, which made them feel early points The fire, and then the pressure is released by it And activating the winding for operating the system and flooding the area surrounding the fire brigade, which works to extinguish the fire in a few moments.

Automatic extinguishing systems for engines and electrical cabinets are classified on the basis of the fire brigade and the method of operating the system as follows:
Direct Pressure Operating System – Using Dry Chemical Powder
Operation theory: At a temperature of 110 ° C, a sudden pressure discharge occurs inside the sensor tube. This sudden pressure release causes the cylinder valve to operate and then the total dumping of the protected area by the fire medium
The extinguishing medium: dry chemical powder.
Operating pressure rating: low pressure.
Cylinder capacity: 2, 4, 6, 12 kg.
System Inclusions:
Line end link with a manometer.
Pressure gauge with switch (to connect to siren or alarm panel).
Pressure switch (to connect to siren or alarm panel).
Siren alarm.

Indirect pressure operating system – using dry chemical powder
Operation theory: At a temperature of 110 ° C, a sudden pressure discharge in the sensor tube occurs. This sudden pressure release causes the cylinder valve to operate and then completely floods the protected area with the fire medium by means of a separate vacuum network.
The extinguishing medium: dry chemical powder.
Operating pressure rating: low pressure.
Cylinder capacity: 6, 12 kg.
System Inclusions:
Line end link with a manometer.
Pressure gauge with switch (to connect to siren or alarm panel).
Siren alarm.
Manual pressure release switch with manometer connection.
Discharge switch (to connect to siren or alarm panel).
Manual discharge switch in the manual.

Direct pressure drive system – using CO2
Operation theory: At a temperature of 110 ° C, a sudden pressure discharge occurs in the sensor tube. This sudden pressure release works to turn on the cylinder valve and then completely flood the area to be protected by the fire medium.
Extinguishing Medium: carbon dioxide gas.
Operating pressure rating: high pressure.
Cylinder capacity: 2, 6, 10 kg.
System Inclusions:
Line end link with a manometer.
Pressure gauge with switch (to connect to siren or alarm panel).
Pressure switch (to connect to siren or alarm panel).
Siren alarm.

Indirect pressure operating system – using carbon dioxide gas
Operation theory: At a temperature of 110 ° C, a pressure discharge in the sensor tube occurs. This sudden discharge causes the cylinder valve to operate and then completely dumped the area to be protected by the fire medium through a separate vacuum network.
Extinguishing Medium: carbon dioxide gas
Operating pressure rating: high pressure.
Cylinder capacity: 25, 45 kg.
System Inclusions:
Line end link with a manometer.
Pressure gauge with switch (to connect to siren or alarm panel).
Pressure switch (to connect to siren or alarm panel).
Siren alarm.
Manual pressure release switch with manometer connection.
Discharge switch (to connect to siren or alarm panel).
Manual discharge switch in the manual.
Examples of applications that are protected by the automatic extinguishing system for engines and electrical cabinets:
Electrical panels.
Control panels.
Containers of flammable liquids.
Bus engines.
Ship engines.
Noticeable :
Due to the effectiveness of these systems, they can be used to protect against risks in various applications. Then, Bavaria encourages its customers to request technical inspections to assess the risks and study the possibility of using these systems to protect these applications.
