FALCO 300 Catalytic Oxidizer Flowrate/Inlet Pressure Calculator (Remediation / SVE units)

    rev 12/6/12 This calculator may be applied to any FALCO 300 oxidizer sold after 1/1/2012.

This calculator provides an estimate of flow through a FALCO 300 at a catalyst temperature of 330°C with the heat exchanger bypass valve closed**.

Alternatively, if the Flow rate is known, Inlet Pressure may be estimated.

    Known Inlet Pressure:        
    Enter Inlet Pressure
(in H2O)
    Estimated Flow Rate =
    Known Flow Rate:        
    Enter Flow Rate
    Estimated Inlet Pressure =
(in H2O)
    Opening the heat exhanger bypass valve will reduce pressure drop by    
    approximately 3-6 in H2O.***          
  * Flow greater than 360 scfm is beyond the normal operating range.
  ** FALCO 300 is normally operated with heat exchanger bypass closed at concentrations < 800 ppmv
  *** FALCO 300 may be operated with the heat exchanger bypass open at high concentrations
  Inlet pressure assumes a clean flame arrestor.
  The FALCO 300 has a high efficiency heat exchanger.
  High efficiency is accompanied by increased pressure drop.
  Heat recovery is adjustable with a heat exchanger bypass valve.
  Lowering heat recovery reduces pressure drop.
