FTE & FTES Float & Thermostatic Steam Trap

Brand: Watson McDaniel

FTE and FTES Series are high capacity steam traps specifically designed to remove condensate and air from HVac and industrial process applications with extremely high condensate load requirements. Examples include reboilers, absorption chillers, large air-handling coils, large heat exchangers and other large process equipment.

They are available with a ductile iron (FTE) or steel body (FTES) and contain a high quality welded stainless steel thermostatic air vent and stainless mechanism. F and T traps have excellent air-handling capability, making them a better choice than Inverted Bucket traps for most process applications.
  • Ductile Iron has a higher pressure and temperature rating and is more resistant to shock loads than Cast Iron
  • Cast Steel Body will allow operating pressures and temperatures up to psig: 300 (kPa: 2,068, bar: 20.68) and 232.2° C (450° F)
  • High capacity steam trap for draining large process equipment (over 100,000 lbs/hr)
  • All stainless steel internals with hardened seat and wear parts
  • In-line repairability is simplified by having all internals attached to the cover
  • Welded stainless steel thermostatic air vent resists shock from waterhammer. Live orifice air vent is available for superheated applications
  • Excellent air handling capability allows air to be discharged rapidly so steam can enter the system quickly during start-up
  • F and T traps discharge condensate immediately as it is formed (no condensate will back up into the system)
