UNITED Fire Systems is pleased to announce our FREE NITROGEN-PAC™ Equipment Selection Guide. This easy-to-use tool is designed to determine which NITROGEN-PAC™ equipment is right for your sprinkler system(s). Simply provide a few items of information about your sprinkler riser(s), and receive links to:
A customized Bill of Material,
Data sheets for all required NITROGEN-PAC™ components,
Instruction manuals, checklists, and information sheets for installation, commissioning, and maintenance,
Ready-to use architect & engineer specifications, along with drawing details.
Whether you are a contractor, estimator, or engineer, this tool is for you. Follow these simple instructions to download and use the NITROGEN-PAC™EQUIPMENT SELECTION GUIDE:
B.Save the file to your computer, and open using Microsoft Excel.
C.Use STEP 1 – PIPE VOLUME CALCULATOR to determine the pipe volume (in gallons) of each sprinkler riser, using pipe lengths and sizes.
D. Use STEP 2 – INDIVIDUAL SPRINKLER RISER INFORMATION to enter the required information for each sprinkler riser:
– Type of riser (preaction or dry-pipe)
– Pipe volume (in gallons) – information from STEP 1
– Supervisory pressure (in PSIG)
To make it easier to gather the necessary information for this step, see our Project Survey Form.
E. Use STEP 3 – OPTIONAL COMPRESSOR FOR PREACTION SYSTEMS to decide if an external air compressor for initial-fill with air makes sense for your system.
F. Use STEP 4 – SYSTEM CHOICE to review the chosen system and click for your deliverables.
That’s it – four simple steps and you are ready to specify, install, commission, use, and maintain a NITROGEN-PAC™ system. Refer to the INSTRUCTIONS page in the file for more detailed guidance. Start using this valuable tool today!

Did You Know?
Your wet-pipe sprinkler system may not be as filled with water as you expect it to be. A bubble of air may migrate to the highest point in the system, creating a very vulnerable location for internal pipe corrosion. That’s why NFPA 13 now requires that all new wet sprinkler systems be fitted with an air vent at the system’s highest point. This is a good investment for both new and existing systems. The UNITED Fire Systems Model AR-1 automatic air release device is Factory Mutual (FM) Approved for just this function. See here for more information, and take action to prevent damaging corrosion.
