Brahma 30282325 CM32 control box

Brahma CM32 30282325 burner control provide efficient control of gas burners with a fan operating independently of combustion in the circuit. These units can be equipped with both non-volatile and volatile locking. They provide the possibility of manual intervention to restart in the event of an emergency lockout or automatic recovery through a power outage. The use of burner control units CM32 30280055 is common in steam convectors, heating boilers, warm air generators, radiator tubular heaters and water heaters. They use an ionization-based flame detection mechanism, although without protective resistance, which potentially makes contact with the detection electrode dangerous.

Features

Construction

The CM32 30282325 gas firing device has a robust housing made of plastic and self-extinguishing material, providing reliable protection against mechanical damage, dust and dirt. This not only prolongs the service life of the device, but also reduces the risks associated with exposure from the external environment. Optimization of the dimensions of the printed circuit board using a module with electronic components on the surface led to a reduction in the size of the device and an increase in its efficiency.

The principle of operation

When turned on, the controller performs self-monitoring and checks of components, including a flame signal amplifier and an air pressure switch. In case of malfunction detection, the controller is locked, ensuring the safety of the system.
