PROINERT®2 … flexible, cost-effective and environmentally friendly fire suppression

Published:  13 May, 2015

COMPANY PROFILE Fike Corporation is a globally recognised supplier of precision-engineered solutions for fire protection, pressure relief, overpressure protection and pressure activation. 

Because so much is at stake™, since 1945 our highly skilled workforce has designed and built solutions for Fortune 500 companies and businesses around the world that want peace of mind from experiencing consequences of serious financial loss or a devastating disaster. When it comes to fire suppression systems, there are many choices. Fike offers a full range of fire detection, suppression and monitoring systems for industrial, commercial, and special hazard applications. 

There are also many factors that go into selecting a system that protects your budget, building, assets and occupants.  In today’s fire suppression landscape, changing regulations mean environmental protection should also be considered.  Fike can help meet your needs with the safest, most cost-effective, environmentally responsible fire protection solution – PROINERT2.

Since its introduction in 2003, PROINERT has become widely accepted as the best performing, most cost-effective and environmentally friendly inert gas fire extinguishing system. PROINERT®2 offers the same technology you are used to with these added benefits:

  • Actuation at the valve, for greater cost savings
  • More flexibility with three additional inert gas options
  • Increased choice of nozzle sizes

Not Your Ordinary Inert Gas System

PROINERT2 features a unique, constant flow valve which eliminates the potentially hazardous pressure peaks associated with most inert gas system discharges. With PROINERT, the gas is delivered at a steady rate, reducing venting requirements and allowing for the use of low pressure piping across longer spans - providing significant cost savings and reducing potential risk. In addition to the savings realized because of the constant flow rate valve technology, Fike’s new Universal Valve Operator (UVO), allows for actuation right at the valve, eliminating the need for additional hardware.  Fewer parts mean you benefit from a reliable fire suppression system at a fraction of the cost.

Zero Global Warming Potential & 100% Chemical-Free. 

Fike’s PROINERT2 system uses agent made from natural gases found in the air we breathe and poses no harmful toxicity issues associated with some widely used popular chemically-based fire suppression agents.  The 100% natural PROINERT2 agent has a global warming potential of zero.  When the agent is released into a normally occupied space, it has no harmful effect on people, property or the environment. Protecting your assets with PROINERT2 is not only good business, it’s good for the planet.
