proinert_headerThe Complete Package

Since its European introduction in 2003, Fike’s innovative ProInert® has become widely accepted as one of the best performing, most cost-effective, and proinert_cylindersenvironmentally friendly inert gas fire extinguishing systems. Now that same technology is available in the United States, and other parts of the world requiring UL and FM approval.

Fike’s ProInert offers all the benefits of other inert gas systems with several significant design improvements – enhancements that not only mean a superior product, but savings to your bottom line!

Most inert gas systems discharge from the nozzle into the protected space with a high surge flow rate, creating a hazardous pressure peak. These systems use pressure reducers further down the pipe network in order to mitigate safety issues, but also require both high-pressure and low-pressure piping.

ProInert is Better

proinert_flowrateBecause of its unique patented valve assembly, the ProInert agent enters the protected room within the industry required 60 seconds, but at a steady flow rate — preventing destructive turbulence from occurring. This constant flow rate means you can use small-diameter, low pressure (and less expensive) piping from the inert gas container, all the way to the nozzle. And the necessary venting area is much smaller – reducing installation costs by as much as 60% on venting hardware.

ProInert’s patented constant flow rate valve translates into a system that is not only safer for your staff and facility, but also saves you money.

Other ProInert Inert Gas System Benefits:

  • Zero Ozone Depletion for maximum environmentalism
  • Superior design allows for convenient long pipe runs
  • Constant flow rate reduces hazardous pressure peaks
  • Globally Approved
  • Typically requires less floor space than other inert gas systems

USGBC LEED® Recognized


While inert gas fire suppression systems are an excellent, environmentally sound means of protecting key assets and rooms, one thing is clear—adding an additional 50% volume into a protected space (the fire suppressant agent) will cause a pressure increase, which can cause damage to the room, if not vented. With High-X vents, pressures are kept within acceptable levels and the inerting gas remains in the protected space for the required time, to allow the fire to be completely extinguished. And the patented High-X design makes it the most economical choice in fire suppression venting.
