The NITROGEN-PAC SC (Self-Contained) Series is a family of FM Approved nitrogen-based sprinkler corrosion inhibiting systems, providing high-purity dry nitrogen for the interior of preaction and dry sprinkler piping. These units feature a compressor for system fast-fill and nitrogen generation, refrigerated drying of the air for the lowest possible moisture content, and membrane technology for efficient nitrogen generation. The SC Series factory-assembled units save space and shorten installation and commissioning time.
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.
