SHEM Series cross Trap psi apacity sq. ft. EDR* * Ratings are in accordance with recommended standards established by the Steam Heating Equipment Manufacturers association (SHEM). sq. ft. EDR is equivalent to a heat emission of 240 TU per hour with 2 psig steam filling a radiator surrounded by 70 F ambient air. To convert sq. ft. EDR to lbs. of condensate, or steam per hour, divide the sq. ft. rating by 4. NPT SPT NPT SPT Pressure Model Model Size Part Part Rating Weight Number Number in. Number Number psi (bar) lbs.
