Sprinkler systems that are run from a works main air supply or separate compressor can use one of our Air Maintenance Devices to automatically control the air that enters the system. This device will keep the air at both the right volume and pressure required for correct operation.
Automatic Air Control
The unit will also allow for air pressure to be reduced where the plant compressed air supply pressure is higher than that needed to operate the sprinkler system. The air supply is fed through an orifice plate so that should a sprinkler head operate the supply will not interfere with the operation of the dry valve.
Dry Pipe Systems
We recommend that for dry pipe systems a low pressure alarm valve is included that will monitor the overall air pressure and signal if it falls below the pre-set alarm value. When a sprinkler head is triggered in a dry system, the system pressure will drop and the dry pipe valve will trip leading to the system filling with water.
