Dry Sprinkler Systems

A dry sprinkler system is a sprinkler system that occupies pressurized air or nitrogen through a piping system, rather than water. When a fire has been detected and the automatic sprinklers have been triggered (the rising temperature will surpass the predetermined threshold), the sprinkler head opens and allows the air from the piping to ventilate through. As the air pressure in the piping system drops, the dry pipe valve opens and water will flow through the piping system and out of the sprinkler head.

Dry sprinkler systems are the second most common sprinkler system as they are installed and used in spaces that are susceptible to freezing temperatures. Dry sprinkler systems are mostly installed in unheated areas such as parking garages or other unheated buildings. Certified Red Seal journeymen at Metro Fire Protection Ltd. have the trained skills and abilities to design, install and repair dry sprinkler systems for a variety of industries, including commercial, industrial, government, residential and high-rise projects.
