COLD ROOM PRESSURE RELIEF

Pressure Relief Valve (PRV) Calculator

Calculate volume from internal floor area × height and make a preliminary valve selection using FERMOD or Intertecnica methods.

Open PRV calculator

Inputs: Internal floor area (m²) × height, temperature and temperature-change rate
Valve selection: FERMOD · Intertecnica
Use limitations: Preliminary selection only. Verify manufacturer limits and panel pressure requirements. Intermediate-temperature assumptions require explicit opt-in.
