The Brahma CM12F 37103252 controllers are high–tech controllers specially designed for controlling gas atmospheric burners with a fan in the combustion circuit or working without it in non-constant operation conditions.


• Steam convectors;

• Heating boilers;

• Warm air generators;

• Radiator tubular heaters;

• Water heaters and other gas installations with an atmospheric burner.


• Type of EU certification (CE PIN code 0694BR1154) in accordance with Directive 90/396 on gas appliances and the following amendment to Directive 93/68;

• In accordance with EN 298 (European standard for automatic programming and flame control systems for gas burners);

• Flame control based on the rectifying properties of the flame (ionization);

• Two independent safety contacts in series at the outlet of the gas valve (models with manual reset);

• Service life of electrical equipment at max. declared load > 250,000 operations;

• Built-in fully solid-state ignition device with high efficiency;

• Auxiliary contact for low-power ignition or control of the main gas valve in intermittent power control systems (this contact is not isolated from the main supply voltage by reinforced insulation, therefore the relay contact is not suitable for controlling SELV circuits

The design includes a durable plastic container designed for reliable protection against impacts. The use of an innovative “box-shaped” design gives the device compactness and increased efficiency. Additional elements such as a varistor to protect against transient voltage, a built-in fuse and a flame detection system based on the rectification effect ensure reliable and safe operation.

The Brahma CM12F 37103252 relay guarantee a long service life, successfully performing more than 250,000 operations. In addition, they provide additional features such as manual unlocking, built-in ignition and an auxiliary contact for low-power ignition. These characteristics provide high functionality and flexibility in use.

The Brahma CM12F 37103252 oil burner safety control boxes comply with CE standards and certifications in accordance with the European Gas Directives, and also meet the requirements of the EN298:2003 standard. This ensures compliance with the high standards of automatic control systems for gas burners, ensuring safety and efficiency in use.
