A wide selection of flange sizes, kilowatt ratings, voltages, terminal housings and sheath materials makes these heaters ideal for all types of heating applications.
Flanged immersion heaters are one of the most widely used methods for heating liquids (such as water, oil, heat transfer fluid and corrosive solutions). Designed for use in tanks and pressurized vessels, they 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 utilize standard pipe flanges ranging from 3\" to 14\" 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, vats or irregularly shaped vessels.

恒温器或温度控制Thermostats or Temperature Control
许多螺旋塞和法兰型加热器都配备内置恒温控制器。 在某些安装中，一个罐体内会存在多个加热器，您可以考虑使用一个配备内置控制器的加热器，通过将恒温器接入磁性接触器的保持线圈电路来控制其它加热器。 如果恒温器与加热器分离，那么恒温器传感元件应位于加热器上方约 4 到 6 英寸处。 在需要高精度或更通用的控制方案的情况下，也可以采用其它控制类型。 电子控制和完整控制面板安装起来非常简单。
Many screw plug and flanged type heaters are available with built-in thermostatic controls. In some installations, where there is more than one heater in a tank, you may consider one heater with a built-in control that will control the other heaters by wiring thermostat into the holding coil circuit of a magnetic contactor. If the thermostat is separate from the heater, the thermostat sensing element should be located approximately 4 to 6 inches above the heater. Other types of controls are available where a high degree of accuracy or a more versatile control scheme is required. Electronic controls and complete control panels are easily installed.
