Brahma 18047160 TGRD91 control box

Brahma TGRD91 18047160 gas control units based on KOMPACT series microcontrollers are designed for effective control of gas atmospheric burners. Brahma TGRD91 18047160 gs control units are adapted both for burners with a fan in the combustion circuit, and for those where there is no fan. The units also provide optimal control of atmospheric oil burners in variable operating conditions.

Brahma TGRD91 gas control for Master 4033.250 B230, B360 since 2011, BV110, BV170, BV290 since 2013.
