The Spectrex Wheels Extinguisher is specifically designed for the wheels and under the vehicle. It consists of a Purple-K 90% dry powder which is super-pressurized with dry nitrogen.
The extinguisher is activated by an electrical signal, transmitted by the control box or emergency switch box. The extinguisher status is continuously monitored by the control box, due to the presence of a pressure switch.
Accidental discharge during shipping, installation and maintenance is prevented by an anti-recoil device for the outlet port and a protective cover for the electrical connector.
