  • Automatic drain for a fire protection sprinkler system
    Patent number: 6443173
    Abstract: An automatic auxiliary condensate drain for an automatic dry-pipe type fire protection sprinkler system, wherein condensation which forms within the sprinkler system due to changes in temperature is drained from the condensate reservoir at the direction of a programmable controller. The programmable controller coordinates the opening and closing of inlet and outlet valves so that accumulated condensate is drained from the system, yet the pressurized gas located in the sprinkler system is not allowed to escape. Actuators operate the inlet and outlet valves in response to signals from the programmable controller.
