Abstract
A dry powder fire extinguisher recharging system charges and discharges a bottle with dry powder. The system includes a frame unit and various components associated with it, such as a clamp assembly to clamp a bottle assembly. The bottle assembly has a bottle in a pre-discharge or a discharge condition, and a valve. There are also components including locking plungers, a torque idler to torque and untorque the valve, a fill valve to recharge the bottle assembly, a fill gauge to pressurize the bottle assembly to the required pressures, a recharge line to charge the bottle assembly with the pressurizing agent, a discharge line to discharge a fully charged bottle, and a socket and an extension. The system also has a valve service area to re-service the valve, and a sprayer gun to remove dry powder residue from the valve during re-servicing of the valve.
