Flanged industrial immersion heaters are commonly used in many chemical, petroleum and water based applications. Consisting normally of an ANSI rated flange with several hairpin elements or bugle tubular elements extending from the face of the flange, this flanged immersion heater uses direct heat application to the liquid medium. A thermowell is often used within the bundle of tubular elements to allow for a probe (either a thermocouple, RTD or basic mechanical thermostat) to relay temperature readings to a digital controller that cycles and maintains the desired target temperature. Often a high limit sensor is also used to help protect liquid mediums from over heating and, offers protection to the flanged heater as well.

Wattco flanged immersion heaters allow the flexibility of using many different alloys to help resist corrosion and maintain life longevity of the flanged heater. Steel flanged immersion heaters are typically used for lubricant oils, heavy and light oils, waxes as well as mildly corrosive liquids and low flow gas heating. Process water, soap and detergent solutions as well as demineralised or deionised water applications often use steel flanges. Stainless steel flanged heating elements are used with mildly corrosive solutions as well as severe corrosive solutions. Food applications also use stainless steel for sanitary purposes. The sheath materials used can be steel, stainless steel, copper as well as exotic alloys such as inconel, hastalloy and titanium. Extremely corrosive environments such as salt water should use exotic alloys such as titanium to avoid sheath breach over excessive durations. Industries that use exotic alloys can include military, chemical and process industries.
 

Flanged immersion heaters allow for immediate heat transfer into your liquid medium that is more efficient than most alternative methods of heating. Flanged immersion heaters also adhere to environmental concerns as electric heating leaves no carbon footprint in the ecology. Many applications use flanged immersion heaters as the sole method of heating or, use it in conjunction with existing heating alternatives that allow users to reach target temperatures. Flanged immersion heaters come with 150LBS, 300LBS, 600 LBS or custom made flanges if required. These flanged heaters also come with baffles for sturdy construction, as well as the option to maintain close temperature readings by attaching thermocouples onto sheath of the tubular elements. Digital controllers and hi limit controlers would then be used to maintain proper temperatures and protect the flanged immersion heater from overheating.
