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.
What’s Included with a Dry Air Pac® Advance Series?
All components are pre-piped, pre-tested, and pre-wired for ease of mechanical and electrical installation on site. Each unit comes sized to fill a dry or pre-action sprinkler system to 40 psi in 30 minutes as per NFPA code, all pre-filters are included and pressure switches / pressure regulators preset to industry standards. Every Dry Air Pac® Advance Series also includes a UL Listed, FM Approved Air Maintenance Device, compressor oil and vibration isolators.
Did You Know? The FM Approval on the Dry Air Pac® eliminates the requirement to connect the air intake to the freezer room. NFPA 13 exempts any approved packages from this costly requirement.
