Brahma 37180677 CM32PR control box

The Brahma CM32PR 37180677 gas control units provide highly efficient control of gas burners with a fan operating independently of combustion in the circuit.

The use of burner control units CM32PR 37180677 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.

Features

• Electrical reset

• Double flame

• Atmospheric with a fan

• Complies with EN298:1993

• Complies with EN298:2003 (2)

• Flame control based on ionization

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

• Service life of electrical equipment > 250,000 operations at maximum load

• Built-in solid-state ignition device

• EU certification (CE PIN code 0694BR1154) according to Directive 90/396 on gas appliances

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

• Auxiliary contact for low-power ignition or control of the main gas valve in systems with intermittent power supply (the relay contact is not isolated PRom the main voltage, therefore it is not suitable for controlling SELV circuits)

Construction

The CM32PR 37180677 oil burner control box is an innovative device with a durable plastic body and self-extinguishing material. This design provides reliable protection against mechanical damage, dust and dirt, which not only prolongs the service life of the device, but also reduces the risks associated with exposure PRom the external environment.

Optimizing the dimensions of the printed circuit board is a key element in improving the device. The use of a module with electronic components on the surface led to a significant reduction in the size of the device. This step not only made the device more compact, but also increased its efficiency.
