Brahma Burner Control Unit NDTM11 37587000

The Brahma Burner Control Unit NDTM11 (SKU 37587000) is a microprocessor-based control box for single-stage or two-stage gas and oil burners. It operates on 220–240 V supply voltage, with a safety time of 8 seconds and a pre-purge time of 30 seconds. The unit uses an ionisation electrode or photodiode for flame detection and features a non-volatile lockout with manual reset. It is certified to CE and EN298:2012, has a net weight of 0.2 kg, and is protected to IP00. The body is made of flame-retardant plastic, and it is designed for intermittent operation with a service life of 250,000 cycles under maximum load. Its flame loss reaction time is less than 1 second.

When selecting a replacement control box of this type, ensure the supply voltage, safety time, pre-purge time, and flame detection method match the burner's requirements. The unit must be compatible with the burner's fuel type (gas or oil) and stage configuration (single or two-stage). Installation should be performed by qualified personnel, and the mounting dimensions and connection layout must be verified against the existing unit. The protection class (e.g., IP00) may require proper enclosure or installation to meet safety standards.

Typical failures of such control boxes include no burner start, lockout after the safety time due to no flame signal, or spontaneous shutdown during operation. These can be caused by faulty flame sensors, ignition issues, fuel supply problems, or external safety device triggers. Check the flame sensor, spark generation, fuel supply, and all safety circuits. A non-volatile lockout requires manual reset after resolving the cause.
