Flange heaters are designed for the heating of fluids (water, oil, heavy fuel, glycol, acids, caustic soda, asphalt, etc.) or gases (air, nitrogen, CO2) by natural or forced convection up to 75 kW, 750 V 3-ph, 400 °C, 50 bar. Horizontal or vertical mounting on the vessels for static fluids or inside vessels for fluid circulation heaters. Heaters comprise a very compact bundle of pin heating elements available in various materials compatible with the fluids to be heated (steel, stainless steel, Incoloy®, etc.). The heating elements are welded onto a flange conforming to standard EN 1092-1 or ASME B16.5, with dimensions from DN 32 (1”1/4) to DN 100 (4”). Flange heaters can be equipped with control and safety devices (thermostats, PT100 sensor, thermocouple, etc.) for the measurement of the temperature in the fluid or of the heating elements.
