CA 2384235

A kinetic antifreeze device for preventing a dry sprinkler system from freezing is disclosed. The kinetic antifreeze device contains a longitudinal pipe for guiding air and water flow connected to a dry sprinkler system pipe at a junction adjacent to a drain valve. The longitudinal pipe provides a pressure gauge, an isolation valve, a bleed off valve and a relief disc means for providing over pressure relief. The relief disc means is either a bursting disc device or a rupture disc device which remains closed when the dry sprinkler system is contains only air. The relief disc exits or opens upon fire suppression fluid entering the system after a main supply of fire suppression fluid is actuated by the dry sprinkler system and the pressure increases due to the presence of fire suppression fluid in the dry sprinkler system.
