Brahma 18000002 SR3 control box

Brahma SR3 is a microprocessor controller ("burner automation") designed for automatic ignition control, flame monitoring and safe operation of atmospheric gas burners of both single-stage and two-stage types. The device operates in an intermittent cycle and is suitable for burners with natural draft (without fan) and forced air supply (with fan). Model SR3 (art. 18000002) is a compact and reliable solution for automation of gas systems. It may have different time parameters depending on the batch. Before purchasing, be sure to check the pre-purge time (tv), safety time (ts) and wait time (tw) indicated on the unit housing against the requirements of your burner. Typical combinations: 1.5/5/1.5 s, 1.5/10/1.5 s, 5/10/5 s and others. Application area includes: gas heating and combined boilers (domestic and industrial); air heaters, hot air generators; air heaters, infrared heaters; water heaters, process furnaces, drying chambers; burners Riello, Baltur, Weishaupt, Lamborghini and other brands. Main functions and features Versatility: Supports both single-stage and two-stage burners, making it a flexible solution for different types of equipment. Full automation of the combustion cycle: The unit independently performs the sequence: check for absence of false flame → pre-purge → ignition (first stage, then second if necessary) → combustion monitoring → safe shutdown when flame is lost. Ionization flame detection: Flame detection via ionization electrode (rectification effect). Reaction time upon flame loss is less than 1 second, meeting EN 298 requirements. High class
