FC Series Humidity Exchangers Selection Guide

  • FC100 Series – Compact humidifier for portable systems up to 500W. Weighs less than 100 grams. Gas flows to 16 alpm
  • FC125 Series – Built using low-cost molded parts. The FC125-Series humidifiers are an ideal choice for systems up to 1kW. Gas flows to 75 alpm (gas/gas) and 150 alpm (water/gas)
  • FC200 Series – Ideal for systems up to 3kW, the FC200-Series is a rugged, compact humidifier for mobile and stationary applications alike. Gas flows to 300 alpm (gas/gas) and 450 alpm (water/gas)
  • FC300 Series – Our standard humidifier for gas-to-gas humidification in 5kW systems. Gas flows to 625 alpm (gas/gas) and 2,000 alpm (water/gas)
  • FC400 Series – The FC400-Series is designed to provide ideal humidification for 7-12KW systems. The high pressure model is now being evaluated for use in passenger cars. Gas flows to 1,000 alpm (gas/gas) and 7,000 alpm (water/gas)
  • FC600 Series – The FC600-Series is suitable for gas-to-gas humidification for systems up to 50kW. When operated water-to-gas, this humidifier is a great choice to replace a bubbler in large test stands (80-100 kW). Gas flows to 2,500 alpm (gas/gas) and 7,000 alpm (water/gas)

1 Flow rate recommendations based upon an approach temperature between 4-6 degrees. The optimal dry air inlet temperature range is between 35 and 55°C.
2 Water-to-gas flow rate is based upon a 80-85%RH. See actual performance curves for specific flow rates. Note that the gas pressure must be higher than the water pressure.
3 When ordering, specify port orientation as same side or 180 degree
