Advantages of Dry Air
The Dry Air Pac® has been the sprinkler industry’s benchmark for nearly 30 years in cold storage, freezer room facilities and other installations where moisture removal is essential. Dry air has long been utilized to prevent ice plugs from forming and in the same process reducing pipe corrosion significantly.
By bringing the pressure dew point of the air inside of the sprinkler piping system down to a -40 degree F dew point (note that this is a moisture measurement, not the temperature inside the pipe) moisture is removed from the compressed air supplying the sprinkler system and the process of oxidation is being controlled. In short, this means no ice plugs and significant corrosion protection.
Ice plugs occur when moisture freezes inside sprinkler piping. Using a Dry Air Pac® removes moisture from compressed air, preventing freezing and ensuring system reliability in cold environments.
The ideal air supply depends on your application: compressed air for general use, dry air for cold storage to prevent freezing, and nitrogen generators or Vapor Pipe Shield for corrosion mitigation.
