273-056 Heating Element, 9 kW, 415 V ac

RS PRO Industrial Incoloy Sheathed Water Heaters_x000D_ Introducing the comprehensive range of industrial immersion water heater elements from our RS PRO range. These rod adjustable thermostats feature an Incoloy sheathed heating element perfect for hot water heating. Incoloy generally refers to nickel based alloys designed for excellent corrosion resistance and strength at high temperatures.These heating elements work particularly well in heavy duty/hard or aggressive waters._x000D_ Options include:_x000D_ 272-996 - INCOLOY SHEATHED WATER HEATER, 3KW 11 inch_x000D_ 273-006 - INCOLOY SHEATHED WATER HEATER, 3KW 30 inch_x000D_ 273-012 - INCOLOY SHEATHED WATER HEATER, 4KW 11 inch_x000D_ 273-028 - INCOLOY SHEATHED WATER HEATER, 4KW 16 inch_x000D_ 273-034 - INCOLOY SHEATHED WATER HEATER, 6KW 16 inch_x000D_ 273-040 - INCOLOY SHEATHED WATER HEATER, 6KW 30 inch_x000D_ 273-056 - INCOLOY SHEATHED WATER HEATER, 9KW 14 inch_x000D_ 273-062 - INCOLOY SHEATHED WATER HEATER, 9KW 27 inch_x000D_ 273-135 - INCOLOY SHEATHED WATER HEATER, 12KW 24 inch_x000D_ Features and Benefits:_x000D_ • Wired in single or 3 phase suitable for applications requiring either a single_x000D_ • Control thermostat in the Incoloy 825 pocket, with all dual cut out heaters coming with a rod thermostat (supplied)_x000D_ • Can be immersed in lengths up to 11 - 30 inches_x000D_ • BSP threaded brass head_x000D_ • Hose proof polypropylene terminal enclosure which can be rotated in any position_x000D_ • Fitted with thermostat and jointing gasket_x000D_ Safety features:_x000D_ • Dual cut-out_x000D_ • Separate secondary manual reset safety cut-out (alongside the dual cut-out) which is directly fitted to the actual immersion heater head_x000D_ Applications:_x000D_ Immersion heaters are electric heating elements that are found in water cylinders to heat water. These elements perform like a kettle to heat the surrounding water in the cylinder. One key advantage of an immersion heater element within your heating system is that if the boiler fails, you should still be able to get hot water. The element usually has its own power supply which means that it can be turned on and off when needed so that water is not constantly being heated unnecessarily._x000D_ • Hot water heating_x000D_ FAQs_x000D_ How do water heater elements work?_x000D_ A water heating element is a pair of upper and lower heating elements that fit into a water heater of some sort. An electric current is passed through the elements which then heats the cold water._x000D_ What causes water heater elements to burn out?_x000D_ Below are some causes:_x000D_ Power surge - a sudden voltage increase to the element caused by a power surge can be enough to burn out an element._x000D_ Wires - a bad connection can cause an element to stop working._x000D_ Thermostat tripping out- these have a high limit switch that shuts off power to the elements when temperatures exceed normal._x000D_ Minerals - sediment collects at the bottom of the water heater tank, encasing the lower element. The element is forced to work harder, and will eventually fail._x000D_ Air pockets - these allow the upper element to burn while not immersed in water, resulting in failure._x000D_ Note_x000D_ it is recommended that heaters over 3kW should be used on a 3 phase supply.
