Over the Side Heaters are a popular industrial heating product for economic and practical uses. Using a water-resistant terminal housing, these industrial heaters come in many shapes and sizes to fit within your tank dimensions and specifications. Wattco over the side immersion heaters are custom designed with multiple tubular elements and a thermowell to hold your temperature probe. Shaped to fit within your standard (or non-standard tank) the economic feasibility can meet the budget of any project manager. The mobility of these heaters to be able to be used in more than one container allow it to be the choice of many project managers. Wattco uses high quality stainless steel and other exotic alloys to meet the requirements of any application. Together with a digital control panel, this heater becomes the perfect solution to heating large containers with no access to the liquid except from the top. Brackets are used to support the heater onto the wall of the tank and cold sections are carefully calculated to prevent over heating when water or liquid levels drop below certain levels as a result of evaporation or drainage. Using high quality alloys, Wattco over the side heaters are strong enough to physically withstand many harsh environments both indoors and outdoors. Commonly used in petroleum and chemical industries it is an exceptional choice for projects with limited budgets.
Over the side immersion heaters are specifically designed such that they can be installed in the upper portion of tanks. The substance to be heated is either below the industrial tank heater or onto one side, hence the name. The main advantages of this approach are that ample space is left in the tank for other operations to take place and the heater can easily be removed when the required temperature is achieved within the substance. The heating element of an over the side process heater is usually made from steel, copper, cast alloy and titanium. A coating of fluoropolymer or quartz can be provided for protection.
There are several applications in which over the side heaters can be used such as heating oils of varying viscosities, degreasing solutions, heat transfer oils and caustic solutions.
