Novec 1230 Fire Suppression Calculation Sheets (Excel)

Novec 1230 is technique which is used to stop fires in places like data centres , museums , telecom facilities etc. they use this to save equipment from water or dry chemical agents. to make novec 1230 system work properly , engineers must find out how much agent is required to make it work like manufacturer say (its like 5.9 % to 6.9 % for class A hazards) and they also need to make cylinder storage and piping layout proper. Our free Excel‑based calculation sheets simplify this process by automating key computations: room volume, agent mass, cylinder count, discharge time, and discharge manifold design. Simply input the architectural dimensions, ceiling height, and desired concentration—then let the spreadsheet handle the rest.

Key Features

• Room Volume & Concentration: • Calculates total agent mass using: m=C×ρ×V m = C times rho times V– m: agent mass (kg) – C: required concentration (decimal) – ρ: Novec 1230 density (kg/m³ at 20 °C) – V: protected volume (m³)
• Cylinder & Storage Sizing: • Determines the number of standard cylinders required (14 kg, 28 kg, etc.). • Accounts for cylinder fill pressure and temperature corrections.
• Pipe Network Design: • Provides preliminary piping layout and calculates pressure drops for manifold sizing. • Suggests orifice sizes for rapid discharge (typically < 10 seconds).
• Discharge Duration Check: • Verifies that discharge time meets minimum hold‑time requirements per NFPA 2001.
• Unit Flexibility: • Supports metric (kg, m³) and imperial (lb, ft³) unit systems.
