When using a wet or dry start to start the system, Changsha fm authentication signal butterfly doors, using K = fast response closed nozzle 80 as a fire detection elements, and cross-fire with closed nozzle disposed in the protected area. Fire detection components as early action fast response sprinklers, wet start-up mode deluge valve diaphragm chamber pressure discharge water from the sprinklers start operation, the dry sprinkler boot mode from the start of the discharge operation starts within the dry pipe network pressure, Hunan fm authentication signal butterfly doors, which open dry-start control valve diaphragm chamber discharge pressure of the water, the pre-action valve is open to the water pipe network. The dew point of the air compressor air compressor is provided for a dry sprinkler system for the overall control system -40 ℃ dry air. Air compressor design and the dry sprinkler system piping the gas pressure up to 40psi (2.76bar), signal butterfly doors, the pressure in line with NFPA13 standards, and provide for the normal operation of the twin towers of regenerative air dryer desired higher pressure. Before entering the regenerative air dryer, an air-cooled rear cooler hot gas compressor discharge is cooled to 100? F (38 ℃). With a differential pressure gauge condensation pre-filter can remove oil mist and other impurities can damage the drying tower desiccant. Adjusting the air pressure to the sprinkler system at the same time through a synthetic particle filter and automatic regulator to prevent leakage of desiccant dust down. For ease of installation and electric devices in place mechanism, all parts should be pre-set control, testing and connection.
