Circulation heaters

Circulation heaters are very efficient in heating water, thermal oil and other liquids or air and gasses (like LNG or nitrogen) or even steam. A circulation heater consists of a vessel in which a flanged immersion heater is mounted. By forcing the medium along with the heating elements of the heater, it is reaching the desired temperature very quickly. The circulation heaters can be produced in steel, various stainless steels (304, 316, titanium), Incoloy, and all other sorts of metal which can be found standard on the market (recently Heating Group International supplied a circulation heater in duplex steel).
