Tightness check for gas trains

LD tightness control is designed to verify the absence of inadmissible leaks in gas trains composed by automatic shutoff valves.
The check can be performed before the ignition of the gas burner or after its stop.
This device is used in industrial firing processes and in forced draught burners (when power is higher than 1200 kW, according to EN 746-2 and EN 676).
LD1 is the basic version composed by the electronic control, driven by a dedicated microchip.
LD-LDM upgraded versions consist of electronic control integrated with pressure switches and/or auxiliary valves and/or metal housing.
