Brahma 18047107 TGRD81 control box

Brahma TGRD81 — a modern microprocessor controller ("burner 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 (art. 18047107) is increased pre-purge time (TP) = 30 seconds and safety time (TS) = 5 seconds, making it an ideal choice for burners requiring long purging of the combustion chamber before ignition. This article is a full analogue of 18047102 and 246.124.015, and is also compatible with spare parts for Master air heaters. Application area includes: combined, heating and steam boilers (domestic and industrial); air heaters and hot air generators, incl. 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 (spark up to 17 kV), simplifying the burner design and reducing the number of external components. Increased pre-purge time (TP = 30 seconds) — critically important for systems requiring long purging of the combustion chamber from residual gas before start. Waiting time (TW) is adjustable in the range 1–240 seconds. Safety time (TS = 5 seconds) — if flame does not appear within this time after ignition, the unit goes into alarm
