R3F panel radiators are manufactured in the USA from cold-rolled steel and consist of two panels with three sets of fins. The panels are finished in a gloss powder coat, and are available in many standard colors and over 100 optional colors. These panels are made in lengths from 2’-0” to 29’- ”, and heights from 3” to 29”. Standard piping connections are 1/2” NPT for inlet and outlet piping, and 1/8” NPT for vents (3/4” NPT inlets and outlets are available by special order)
