What does the shop sell?

Spare parts for gas and oil burners and boilers: gas valves, nozzles, ignition electrodes and transformers, pressure switches, flame detectors, fuel pumps, servomotors and burner control boxes.

How large is the catalogue?

Over 100,000 part numbers from every major manufacturer, brought into one structure so that parts from different brands can be compared and replaced.

Can I find a part by its number?

Yes. The order number, the manufacturer model and any supplier code all lead to the same part, so a number from an old invoice or a nameplate is enough.

Description

This Brahma microprocessor burner management unit (model NDM11PR) is intended for automatic ignition and flame monitoring in atmospheric or progressive burners that operate on gas or liquid fuel in intermittent mode. It accepts 220–240 V, 50–60 Hz supply, carries out a 30 s pre-purge, and has a 3 s safety time. Flame control is by ionisation electrode or photodiode FD. Its built-in high-voltage ignition transformer, EMC filter and varistor are housed in an IP40 enclosure that withstands -20 to +70 °C and measures 10.7 x 8.1 x 3.6 cm.

Further details

Control functions	pre-purge, ignition, flame monitoring and safety lockout
Diagnostics and indication	self-diagnosis and LED indication of operating modes and fault codes
Mounting method	on a DIN rail or inside equipment
Reset method	by briefly interrupting power or by a button (if available)
Safety Feature	safety lockout on flame loss or ignition failure

Signs of failure

Burner management units of this type enter a safety lockout if the flame is lost or ignition fails. The burner then stops and the LED indicates a fault. Reset is done by briefly interrupting the power supply or, if a button is fitted, by pressing the reset button.
