Dry chemical

Benefits

• Low costs compared to chemical gases;
• This technology is not subject to room sealing requirements associated with the saturation mode of ambient air and no integrity (fan test) tests are required;
• System designed in advance (pre engineered);
• Local application authorized;
• Low cost of equipment maintenance.

Required Considerations

• Causes collateral damages during release (dry chemical in protected area);
• Not recommended for gun propellant and cellulose nitrate processes or storage;
• Produces no cooling effect;
• Hydraulic elements must be balanced;
• Reduced visibility during release;
• Ineffective against smouldering fires;
• Not recommended for electric appliances or to protect expensive equipments;
• Can leave corrosive deposits.

Environmental Sustainability

• No global warming potential (GWP);
• No ozone depletion potential (ODP).

Equipment Re-Activation Time

Relatively rapid but requires a significant cleanup.
