• ProInert®2 Gaseous Suppression System

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

Data Sheet

  • ProInert® IG-541 Agent

    IG-541 is a colorless, odorless, electrically non-conductive gas with a density approximately the same as air. (see Physical Properties for additional information).

  • C.2.28.01 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.

  • C.2.29.01 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.

  • C.2.30.01 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.

  • C.2.32.01 ProInert® Discharge Manifolds

    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.

  • C.2.41.01 ProInert® Selector Valve Assembly

    Fike offers several selector valves for use with the ProInert Fire Extinguishing System. The Selector Valve allows a single agent supply to be utilized for protection of multiple hazards, reducing the total number of cylinders required.

  • C.2.47.01 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.

  • C.2.48.01 ProInert® Pipe & Fittings

    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.

  • C.2.49.01 ProInert® Dishcarge 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.

  • C.2.50.01 ProInert® Actuation Packages

    Each ProInert cylinder or group of cylinders being actuated simultaneously (up to 60 cylinders) requires a nitrogen actuator for valve activation.

  • C.2.51.01 ProInert® Mounting Hardware

    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.

  • C.2.57.01 ProInert® IG-541 Agent Storage Assembly

    Fike ProInert Cylinders are offered in an 80 Liter size and filled to a pressure of 200 or 300 bar. The cylinders may be utilized in single or multiple cylinder applications as needed and linked together through a common discharge manifold.

  • C.2.60.01 ProInert® Pressure Gauge Switch

    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.

  • C.2.63.01 ProInert® Instructional Signs

    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.

Application Profiles

  • FSAP001 Hot Aisle/Cold Aisle For Data Center Applications

    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.

Fact Sheet

  • FS08-003 Safe Handling of ProInert Cylinders

    The purpose of this bulletin is a reminder to practice the proper safe handling of ProInert cylinders.

  • FS10-003 Return of ProInert Cylinders for Refill and Service Exchange

    The purpose of this bulletin is a reminder to enforce the proper way to prepare ProInert cylinder/s ready for return to be refilled.

  • FS12-002 ProInert Valve Operation

    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.

  • PITB06-001 ProInert Pressure Gauge Installation

    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.
