The Inert Gas System so safe it even protects your budget.

PROINERT™ IG-01 is a clean agent fire extinguishing system using an inert gas (IG-01) consisting of 100% Argon and is used in total flooding systems. PROINERT™ has become widely accepted as the best performing, cost effective, and environmentally friendly inert gas fire extinguishing agent, offering extended hold times and great flexibility in design.  The patented pressure regulating discharge valve used in the PROINERT™ system utilises a superior valve design to automatically regulate the pressure of the extinguishant at discharge, providing an ideal discharge pressure and maintaining a constant flow rate throughout the discharge.

04-01 ProInert® Discharge Pressure Switch

Fike’s Discharge Pressure Switch Assembly (DPS) is used to provide a latching electrical input to the control panel to confirm a system discharge/actuation.

04-02 ProInert® Valve Assembly

The ProInert Discharge Valve Assembly is a self-regulating valve that allows the extinguishing agent to be released from the cylinder at a constant pressure. Because pipe pressure and nozzle flow rates remain constant throughout the discharge, small diameter piping can be used throughout the protected space, and the need for installing overpressure relief vents in the room is minimised.

04-04 ProInert® Discharge Hose Kit

The Discharge Hose Kit, IG71-003, is used to provide a flexible connection between the ProInert cylinder valve and the discharge piping or the distribution manifold.

04-05 ProInert® Discharge Nozzles

The function of the discharge nozzle in a fire extinguishing system, is to distribute the agent in a uniform, predetermined pattern and concentration.

04-06 ProInert® Actuator Assembly

Each Fike ProInert Cylinder is equipped with a latching Actuator Assembly that actuates the cylinder valve. The actuator includes a flexible hose that is used to connect it to the next actuator assembly on multiple cylinder systems.

04-07 ProInert® Hush Nozzle

The “Hush” nozzle is a new Proinert innovation with a proprietary mesh interior designed to reduce noise levels during a discharge of the system. While the ProInert constant flow valve already delivers a lower pressure discharge of 42 bar compared to the industry average of 72 bar, the product now operates at significantly reduced noise levels that will not harm equipment.

04-09 ProInert® Universal Valve Operator (UVO) KIT

The Universal Valve Operator (UVO) provides means to electrically or manually activate the Fike ProInert Valve inert gas cylinder by providing the force required to extend a piston that will open the valve, allowing the agent to be released from the cylinder.
