FirePro Condensed Aerosol Fire Suppression System

The FirePro condensed aerosol fire suppression system is a fixed extinguishing solution designed to rapidly control fires inside protected enclosures, equipment and technical spaces.

The system uses compact generators that discharge fine condensed-aerosol particles throughout the protected enclosure. These particles interrupt the chemical chain reaction that sustains combustion, helping suppress the fire without the use of water.

In many applications, FirePro generators can be installed directly inside the protected space, reducing the need for large gas-storage cylinders, extensive distribution piping and multiple discharge nozzles.

This page presents the FirePro fixed aerosol-generator family as one complete system category rather than one individual model. The final generator models, quantities and locations must be determined through approved engineering calculations.

Operating Principle:

Each FirePro generator contains a solid fire-extinguishing compound inside a metal housing.

When the generator receives an electrical or thermal activation signal, the compound produces condensed aerosol and discharges it into the protected enclosure.

The aerosol spreads through the space and primarily suppresses combustion by interrupting the chemical reaction within the flame.

System performance depends on:

• Correct extinguishing-compound mass.
• Generator distribution.
• Net enclosure volume.
• Hazard and fuel type.
• Enclosure integrity.
• Installation height and orientation.
• Detection and activation method.
• Required concentration-holding period.

Available Generator Family:

The FirePro catalogue includes a broad range of fixed aerosol generators, including:

• FP-20.
• FP-40.
• FP-80.
• FP-100.
• FP-200.
• FP-500.
• FP-1200.
• FP-2000.
• FP-3000.
• FP-4200.
• FP-5700.

Selected models may also be available in different configurations, including:

• Multiple discharge outlets.
• Single discharge outlet.
• Stainless-steel enclosure.
• Coated carbon-steel enclosure.
• Electrical activation.
• Thermal activation.
• Combined configuration according to the selected model.

Generator selection must be based on approved calculations, required aerosol-compound mass, hazard type and enclosure design.

Activation Methods:

Electrical Activation:

Generators may be activated by an electrical signal from:

• An extinguishing control panel.
• A dedicated controller.
• A fire-detection system.
• A sequential activator.
• An approved manual-release circuit.

Electrical activation is commonly used in automatic systems that require detection, staged alarm and a programmed release delay.

Thermal Activation:

Selected models can be supplied with thermal activation.

The generator activates when the thermal device reaches its specified operating temperature.

Thermal activation may be used in selected standalone applications or as part of an approved protection strategy.

Manual Activation:

Manual-release devices may be provided through the extinguishing control system.

Manual-release controls must be protected from accidental operation and installed in a clear and accessible location for authorized personnel.

Fire Classes:

The catalogue identifies selected FirePro generators for:

• Class A fires involving solid combustible materials.
• Class B fires involving flammable liquids.
• Class C fires according to the applied classification and intended hazard.

Suitability for the specific protected material and hazard must be confirmed during system design.
