GPM	=	Gallons per minute	^ These selections have two circuits. All the other selections have a single circuit .
PD	=	Water pressure drop in feet of water	^^ All steam coils rated at 5 PSIG Steam.
MBH	=	BTU per Hour in Thousands	** Steam selections for 65 and 75 are two circuits and are 1 inch diameter tube (Type-8).

*To estimate performance of coils at other than 10 FPI or at other air speeds or with other water or air temperatures or other steam pressures see page 23, or call your representative. With your representative, you can have specific computer selected coils rated for your job conditions.
