Flanged Immersion Heaters

Magma Technologies offers a range of Flanged Immersion Heaters, among the most widely used methods for heating liquids (such as water, oil, heat transfer fluid and corrosive solutions). Designed for use in tanks and pressurised vessels, these are easy to install and maintain to provide heat for many processes. The direct immersion method is energy efficient and easily monitored and controlled. These through-the-side immersion heaters utilise standard pipe flanges of various ranges in diameter to support high tank pressures of liquids. They are installed through a matching companion flange, obtainable from local industrial supply houses, to the tank wall. A wide selection of watt densities, heating outputs and flange sizes and ratings make this an excellent heater for all tanks, or irregularly shaped vessels. A thermowell is often used within the bundle of 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. Magma flanged immersion heaters allow the flexibility of using many different alloys to help resist corrosion and maintain life longevity of the flanged heater. Steel flanges 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. These heaters are available in varying kilowatt ratings, voltages, temperature ranges, sheath materials and so on. Typical applications include preheating different grades of oil, cleaning tanks and heat transfer, etc.
