Dollar Loss Table for Radiator Traps
Steam Cost @ $6.00/1000 lbs.
Pressure balanced thermostatic radiator traps are most commonly found on low pressure (25 psig and under) steam heating systems. Located on radiators, convectors and other radiant heat units, there may be literally hundreds of these scattered throughout larger facilities. The operating unit within the trap, a pressure-balanced disc or bellows, is filled with a distilled liquid to respond to the changes in temperature (i.e. pressure) within the trap. The disc or bellows will generally "fail open" after three to five years of hard work (after five years it has opened and closed hundreds of thousands of times). The orifice sizes (*) shown, for all the steam traps, are conservative estimates of the average size found in these traps. Actual dollar loss may be more or less than shown.
