Dry Chemical Fire Suppression System

Dry Chemical Fire Suppression Systems are designed with fixed piping and nozzles to discharge sodium or potassium bicarbonate-based powder over the fire area.
The systems are designed in compliance with EN 12416-2, while testing and maintenance are carried out according to EN 12416-1 and -2.

Therefore, all design, installation, testing, and maintenance must be performed by qualified and certified fire protection professionals.

These systems provide rapid extinguishing, wide coverage, and re-ignition prevention, making them ideal for both local and total flooding applications.

Operating Principle

When activated automatically or manually:

1. The pilot cylinder releases compressed gas (nitrogen or CO₂).

2. This pressure propels the dry chemical powder through distribution piping.

3. The powder blankets the fire surface, cutting off oxygen and interrupting the chemical reaction responsible for combustion.

This dual effect — cooling and chain reaction inhibition — ensures fast and permanent extinguishing performance.

Applications

Dry chemical systems are suitable for environments with flammable liquids, gases, or electrical hazards, including:

• Transformer stations

• Oil reservoirs

• Boiler rooms

• Fuel loading/unloading areas

• Compressor rooms

• Industrial machinery spaces

• Generator rooms

• Paint and solvent storage areas

They perform effectively in both open and enclosed areas, provided that vent and clearance calculations meet standard requirements.

Advantages

• Immediate response within seconds

• High extinguishing efficiency across large areas

• Prevents re-ignition through chemical inhibition

• Safe for human exposure

• Automatic or manual activation options

• Low maintenance and recharge costs

System Components

• Dry chemical storage cylinders

• Pressurizing gas cylinder (Nitrogen or CO₂)

• Stainless steel piping and nozzles

• Manual/automatic actuation valves

• Control and alarm panel

All outdoor or semi-open installations must include ventilation and dispersion calculations according to EN standards.
