Technical Specs of Over the Side Water Heaters Winter is here, and so are the freezing temperatures. During subzero conditions, liquids often cool and ice over. For countless industrial purposes -- ranging from oil extraction to pharmaceutical manufacturing -- that can be bad news for the efficiency of a business. These kinds of temperatures can be immobilizing for the logistics of processing, preparing orders, and filling them correctly and on time. Over the side water heaters hang on the side of a tank that holds liquid and heats said liquid to maintain its temperature or raise it to the necessary heat level. For industrial use, these immersion heaters can be applied to oils, acids, waters and solutions in all areas of engineering and business. Here are the technical specs of over the side immersion heaters so you can keep in mind the best one for your work. Key Features Over the side immersion heaters boast a variety of features that are key to warming any liquid. First, it has a standard 1-inch conduit opening that allows the wires to route through to the rest of the heater. Second, the heating elements come in diameters of 0.315”, 0.375”, 0.430”, and 0.475”. The elements are the central provider of heat to warm the liquid. They take the currents as they pass through the metal and encounter resistance and convert that electricity into heat. The heating elements are almost always placed into sheaths, with ends supported as well, to insulate the wire electrically and keep it safe from unwanted moisture. For over the side water heaters, the sheaths come in materials of steel, stainless steel, copper, Inconel, titanium and Incoloy®. The right type of sheath material depends on its application. For example, for heating water you would choose copper, which is non-corrosive. For oils, steel or stainless steel can prove to be a good, non-corrosive option. Wattage, Voltage and Power In terms of the size and shape, over the side immersion heaters come in single or triple element structures. This essentially means that the former has one heating element, while the latter boasts three. In general, the number of elements affects the size and weight of the heater: while a single is only 8.8 lbs., a triple weighs 22. This, of course, affects where and how you install an over the side heater. Whereas a single element is significantly smaller and can be put into tanks with lesser capacity, a triple element is applied to bigger ones. In addition, a triple element can be utilized in single or three phase power. While the former uses one power conductor, the latter has three. In terms of wattage, they both enjoy 19, 32, or 48 Watts per square inch, depending on the KW reading. Voltage levels include 208, 240, 480, and 600.
