Type CH circulation heaters and CHP circulation packages are compact, self contained units designed to heat flowing liquids and gases, including super heating steam. Circulation heaters can be installed vertically or horizontally for in-line heating, or mounted vertically to a tank as a side arm heater. Circulation packages can be horizontally or vertically designed and are mounted on a skid with a complete control center. Each heating unit consists of a tubular flanged immersion heater mounted in a steel heating chamber. The chamber is equipped with flanged inlet and outlet connections, mounting studs, high temperature insulation and an aluminum jacket. Circulation heaters and packages are available in a wide range of kW sizes, construction materials, NEMA ratings, controls and other options.
