Flange immersion heaters are typically inserted horizontally into a tank or vessel for direct heating of liquids, allowing the fluid to quickly reach the desired temperature and ensure optimized high performance results. We manufacture electric flange immersion heaters for industrial and process heating applications, providing economical and reliable heating for large volume, high power and/or high-pressure applications and for use in smaller pieces of equipment such as Boilers or Calorifiers. Industrial flange immersion heaters provide heating solutions for fluid freeze protection and winterizing, hot or warm water storage, rinse tank heating, process chemical reactors, water-glycol heating, parts cleaning, plating and finishing chemicals, waste oil, wash systems and numerous other thermal heating applications. Typical heating mediums include: Process air Heat transfer oils Clean water Process water Lube and fuel oils Mild and corrosive solutions Wax and molasses Flange materials: steel, 304 and 316 stainless steel Sheath materials: 304 and 316 stainless steel, Incoloy 800 & 840 & Copper. Screw Plug Immersion Heaters consist of tubular elements welded or brazed into a threaded screw plug which can then be inserted into a threaded opening in a tank wall or through a mating full or half coupling. The screw plug immersion heaters consist of one, three or six heating elements which are assembled on a brass, steel or stainless steel plug.
