Dollar Loss Table for Float & Thermostatic Traps

Steam cost @ $6.00/1000 lbs.

Float & Thermostatic (F&T) traps are found where higher levels of condensate are produced (Unit heaters, end-of-mains, heat exchangers, etc.) The modulating control provided by the float allows for continuous discharge of condensate when necessary. The air vent in this trap will generally "fail open" after three to five years of hard work. The mechanism and float assembly, which allows the condensate to discharge, may operate efficiently for eight to ten years, and will normally "fail closed" after this time. However, sludge and debris accumulation may cause the assembly to fail open and waste "big bucks" as shown. Actual dollar loss may be more or less than shown.

LOSS FROM AIR VENT: The air vents in all the F&T traps generally utilize a 1/4" discharge orifice.
