The M300 control box is suitable for gas forced draught burners for gas and oil fuel for civil and industrial applications, with one flame level.
This control can alternatively employ as detection flame sensor both an electrode, which makes use of the rectification property of the flame (ionization), and a UV phototube.
The “Laboratorio di Macchine e Termotecnica del Centro Studi ed Esperienze” in Rome - Capannelle tested the M300 control for power up to 350KW, which obtained the certification n° 3704/142/77/16 and the approval of the Ministry of the Interior for fire prevention (circulars n°68 and n°42). |
