DN 125 (5″) to DN 500 (20″) FLANGE IMMERSION HEATERS

Vulcanic flange immersion heaters are designed for the heating of fluids (water, oil, heavy fuel, glycol, acids, caustic soda, asphalt, etc.) or gases (air, nitrogen, CO2, etc.) by natural or forced convection up to 3000 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.

Vulcanic immersion heaters comprise a very compact bundle of pin heating elements available in several materials compatible with the fluids to be heated (steel, stainless steel, Incoloy®, etc.).

The heating elements are welded onto a flange conforming to standard EN1092-1 or ASME B16.5, with dimensions from DN 125 (5”) to DN 500 (20”).

Flange immersion 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.

An electrical control and power supply unit with IP55 to IP66 protection rating, in painted steel or stainless steel, protects the connections from the heating elements to the power supply and from the control and safety devices to the power cabinet.

Vulcanic flange immersion heaters are designed and manufactured either as part of our standard range or as a customised solution for installation on vessels conforming to European directive 2014/68/EU (PED).
