Steam Radiation

Need some help with this guys.
Surveved a church today for updating the mechanicals and found something I've never seen before. We've got a cast iron heating coil inside an air handler with no markings ther than an ID tag on the cabinet stating "Manufactured for A.M.Castle &Co.--Chicago, IL." This thing is 17 sections wide 2 sections deep(34 sections total), each section being 10inches wide,72inches high & approx. 5inches deep. Anyone have any idea on the amount of EDR or how to figure the same? Thanks in advance.
