Brahma 18047102 TGRD81 control box

Brahma TGRD81 is a modern microprocessor controller ("combustion manager") from the KOMPACT series, designed for full automation of ignition, flame monitoring and safety of atmospheric gas and liquid fuel (diesel) burners of progressive (modulating) type. The device operates in intermittent mode and is equally effective with or without a fan in the combustion circuit. The key feature of this modification is the pre-purge time (TP) = 30 seconds, making it indispensable for burners requiring long purging of the combustion chamber before ignition. Application area includes: combined, heating and steam boilers (domestic and industrial); air heaters and hot air generators, including Master BV70, BV110, BV170, BV290, B230, B360, OKLIMA; radiant tube and convector heaters; water heaters, process furnaces, monoblock burners; burners Riello, Weishaupt, Giersch, Viessmann, Lamborghini and other brands. Main functions and features Built-in high-voltage ignition transformer — the device combines a programmable controller and a powerful ignition system, simplifying the burner design and reducing the number of external components. Extended pre-purge time (TP = 30 seconds) — critically important for systems requiring long purging of the combustion chamber from residual gas before start-up. Wait time (TW) is adjustable in the range of 1–240 seconds. Safety time (TS = 5 seconds) — if flame does not appear within this time after ignition, the unit emergency shuts off fuel supply and goes into lockout. Non-volatile emergency lockout with manual reset — in any abnormal situation (flame absence, ignition failure, ionization circuit break, etc.) the unit pe
