🔥 Fire Suppression Calculator
Protect your critical assets with the ThermoFlowPro Fire Suppression Calculator. This advanced engineering tool is designed to help MEP consultants and fire protection engineers calculate the required gas quantity for clean agent systems like FM200 (HFC-227ea) and CO2 (Carbon Dioxide). Our calculator ensures your design meets the stringent safety requirements of NFPA 2001 and NFPA 12, providing precise volume-to-agent ratios for server rooms, electrical rooms, and industrial hazards.

Supported Systems
FM200 (HFC-227ea) Calculation
The FM200 system is the standard for occupied spaces. Our tool calculates the agent weight based on:
Room Volume: Total cubic meters/feet of the protected hazard.
Design Concentration: Usually between 7% to 9% depending on the hazard type.
Ambient Temperature: Factoring in the minimum expected temperature of the protected space.
CO2 (Carbon Dioxide) Suppression
Used primarily for unoccupied spaces and local application. The calculator determines:
Total Flooding Quantity: For enclosed rooms based on volume factors.
Surface Hazards: Specific calculations for flammable liquids or electrical equipment.
Technical Design Factors
Altitude Correction: Adjusting gas weight based on the building’s height above sea level.
Leakage & Design Margins: Adding safety factors to ensure the design concentration is maintained for the required “Hold Time.”
How to Calculate Gas Quantity?
Measure the Room: Calculate the Gross Volume ($Width \times Length \times Height$).
Select the Agent: Choose between FM200, CO2, or Novec 1230.
Define Temperature: Enter the lowest expected room temperature.
Result: The tool provides the Total Agent Weight and the required cylinder size.
FAQ
- Q: What is the “Hold Time” in fire suppression? A: It is the duration the gas must remain at the design concentration (usually 10 minutes) to prevent re-ignition.
- Q: Can I use CO2 in an occupied office? A: No, CO2 is lethal at design concentrations. Clean agents like FM200 or Novec 1230 are safer for occupied spaces.
