Circulation Heaters In-Line Heaters Guide:![]() ![]() Circulation/Inline Heaters-Components Circulation Heaters, Re-Circulation Heaters
CIRCULATION HEATERS PRODUCT DESCRIPTION GUIDE: Circulation heaters, also referred to as in-line or re-circulation heaters are used for heating flowing liquids and gases. Non-pressurized or highly pressurized fluids can be heated very effectively using either direct or indirect circulation heating. A wide variety of standard designs and custom engineered power ratings, sizes, flow capacities and options are available to fulfill most any application needs.
NPH circulation heaters feature all-welded construction of the steel shroud and flanges, hydrostatically pressure-tested ports, heavy-duty metal-sheathed heating elements of Incoloy or steel, galvanized or carbon steel containment pipe, NEMA1 terminal housings, bulb & capillary thermostats or solid-state controls, plus up to a 150-lb. forged steel flange with bolt construction connecting the terminal housing and containment vessel.
