Brahma CM32PR 37180679 gas firing devices provide highly efficient control of gas burners with a fan operating independently of combustion in the circuit.

The use of burner control units CM32PR 37180679 is widespread in various technical devices such as steam convectors, heating boilers, warm air generators, radiator tubular heaters and water heaters. They use an ionization-based flame detection mechanism.


1. Electrical reset: A mechanism that allows the system to be reset electrically if necessary.

2. Double flame: A function that provides an additional control flame to increase the safety of the system.

3. Atmospheric with fan: The device is designed to operate in atmospheric conditions and is equipped with a fan for efficient operation.

4. Compliance with EN298:1993 and EN298:2003 (2) standards: This device complies with European standards for automatic programming and flame control systems for gas burners.

5. Flame control based on ionization: The flame detection mechanism is based on the ionization process, which ensures the reliability of flame detection.

6. Two safety contacts at the outlet of the gas valve (models with manual reset): This provides additional safety measures for models with manual reset.

7. Long service life of electrical equipment: The device is capable of performing more than 250,000 operations at maximum load, which indicates its high reliability and durability.

8. Built-in solid-state ignition device: This is a reliable ignition mechanism using solid-state components.

9. EU Certification (CE): The device is certified by the EU Directive 90/396 on gas appliances.

10. Auxiliary contact for low-power ignition or control of the main gas valve in intermittent power systems: This contact makes it possible to control the gas valve under specific conditions, but its characteristics should be taken into account in the context of use.

The CM32PR 37180679 controllers is an innovative device with a robust housing made of self-extinguishing material that provides reliable protection against mechanical damage, dust and dirt. This device has an optimized PCB structure with electronic components on the surface, which significantly reduces its size and increases efficiency. The CM32PR 37180679 firebox provides high reliability, long service life and optimal performance due to its compact and efficient design.

The principle of operation

Upon activation, the CM32PR 37180679 controller performs automatic self-monitoring, which includes a thorough check of all components. This process includes detailed testing of the flame signal amplifier and the air pressure switch, two key elements of the system.

In case of detection of any malfunctions during self-monitoring, the controller immediately enters the lock mode. This ensures reliable protection and safety of the entire system. Locking the controller prevents possible negative consequences and provides an opportunity to promptly eliminate the identified problems.

Such a self-monitoring and automatic locking mechanism ensures that the CM32 30379516 firebox operates with the highest level of reliability and safety, which is especially important in industrial processes.
