PROINERT™ IG-55 is a clean agent fire extinguishing system using an inert gas (IG-55) consisting of 50% Nitrogen and 50% 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.
IG-55 is a colorless, odorless, electrically non-conductive gas with a density approximately the same as air. (see Physical Properties for additional information).
Fike ProInert Cylinders are offered in an 80 Liter size and filled to a pressure of 200 or 300 bar. The cylinders may be utilised in single or multiple cylinder applications as needed and linked together through a common discharge manifold.
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.
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.
The function of the discharge nozzle in a fire extinguishing system, is to distribute the agent in a uniform, predetermined pattern and concentration.
ProInert manifolds are offered in 2, 3, 4 and 5 cylinder configurations. For systems that require more than 5 cylinders, manifolds must be interconnected into a common feed pipe.
Caution/Advisory Signs are provided to comply with ISO/EN and/or NFPA 2001 requirements, and to provide the necessary information to personnel in the area.
Fike offers several selector valves for use with the ProInert Fire Extinguishing System. The Selector Valve allows a single agent supply to be utilised for protection of multiple hazards, reducing the total number of cylinders required.
Each Fike ProInert Cylinder is equipped with a Pressure Gauge and Switch Assembly to indicate a visual pressure indication at the cylinder, as well as continuous cylinder pressure monitoring at the control panel. The Pressure Gauge scale is calibrated to show the actual pressure, as well as a color-coded acceptable operating range, under-pressure range, and over-pressure range.
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.
Pipe and fittings used in Clean Agent System piping network must conform to the requirements as outlined in NFPA 2001 and ISO 14520, latest editions.
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.
Each ProInert cylinder or group of cylinders being actuated simultaneously (up to 60 cylinders) requires a nitrogen actuator for valve activation.
All ProInert cylinders must be adequately mounted and supported to suitable mounting surface. Fike offers a racking system for multi-row configurations to secure the cylinders. The racking consists of the hardware necessary for assembly, including front support, rear support and clamp rods. The various racking options available provide the installer with multiple options for cylinder arrangement. Cylinders may be mounted in Single-Row, Double-Row or Triple-Row configurations.
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.
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.
Due to concerns over more efficient cooling of equipment and the need to reduce operating costs, today’s data centers are going through an efficiency evolution. Often changes include Hot Aisle / Cold Aisle Configurations, Aisle Containment Curtains, Hot Aisle Containment, and Cold Aisle Containment.

NOTICE OF AUTHORISATION TO APPLY THE UL MARK
The purpose of this bulletin is a reminder to practice the proper safe handling of ProInert cylinders.
The purpose of this bulletin is a reminder to enforce the proper way to prepare ProInert cylinder/s ready for return to be refilled.
Fike developed the first pressure/flow regulating valve for fire suppression systems in 2003. Since that time Fike ProInert systems have been safely applied to thousands of hazards to protect vital assets, critical processes, and protect against business interruption.
Fike is issuing this bulletin as a reminder of the proper way to install a ProInert pressure gauge. This procedure applies to both 200 bar and 300 bar systems. It is quite simple and involves the following steps: 1) Carefully screw the pressure gauge into the pressure gauge port, being careful not to cross the threads. 2) Continue screwing the gauge in until it bottoms out into the port.
Lunch & Learn sessions involve Fire Protection Technologies Product Specialists hosting presentations that cover specific system information, which can be tailored to suit your applications.
