R3F radiators are mounted horizontally and consist of two layers of fins sandwiched between two layers of panels and a third row of fins on the backside.
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 powdercoat, 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). For more complete R3F specifications, please refer to the Runtal technical pages.
