FC125-240 Series

FC125 Operating Specifications

  • Operating fluid pressure range: 0 to 172 kPa ( 0 to 25 psig) @ 80°C (176°F)
  • Operating fluid temperature range: 1 to 80°C (33 to 176°F)
  • Maximum Pressure differential on tubing: 35 kPa (0 to 5 psid) @ 80°C (176°F)
  • Negative pressure differential will collapse tubing and must be avoided
  • Storage temperature range: -30 to 60°C (-22 to 140°F)

FC125 Materials of construction

  • Housing – Shell –Polypropylene
  • End caps – GE Noryl Seals – EPDM (peroxide cured)
  • Tube bundle headers – Thermoset polyurethane
  • Membrane tubing – Nafion®

IMPORTANT –  WARNING!  Due to differing rates of expansion, metal fittings are not recommended. ABS or Nylon fittings are required. Additionally, DO NOT USE teflon tape when attaching fittings to Perma Pure humidifiers. Using either metal fittings or teflon tape will cause the end caps to crack, leading to leaks (and voiding the warranty).

* The performance information for the gas-to-gas units are expressed as the flow rate of air (slpm) in relation to the approach dew point temperature. The approach temperature is defined as the difference between the cathode exhaust stream entering the humidifier and the humidifier exhaust stream going to the stack. For example, if the cathode exhaust dew point entering the humidifier is 67° and the humidifier generates a dew point of 61°, it would have been sized for a 6° approach temperature.
