Circulation Heaters, also known as “in line heaters,” have uses in many applications. They can use steel, stainless steel, or titanium depending on the application. Lube oil and waste oil applications often use steel for circulation heaters. This is because it is fairly inexpensive compared to stainless steel counterpart. Water circulation heaters use stainless steel because of its anti-corrosive qualities. In both applications, a pump flows the liquid, such as water or glycerol, through a closed pipe circuit. The liquid is reheated as it flows through the circulation heater. A major consideration for this application is viscosity. Electric circulation heaters generate heat, making the medium less viscous. The less viscous the fluid, the easier it is to pump through a circuit of pipes.
Industrial circulation heaters come in a range of watt densities. Watt densities are specifically designed for the medium they will heat. The required wattage to heat the oil or water is highly correlated to the flow rate (in GPM).
Insulation is often required for vessels to preserve the heat within the vessel. This results in efficient heat application, reducing unnecessary costs through heat loss. Electric circulation heaters can use digital thermocouple probes or RTDs. This allows them to maintain the oil or water at the preferred temperature. Many applications use liquids with low flash point. These require explosion-proof housing (NEMA 7) to avoid potential mishaps.

Other useful features found with electric circulation heaters are drain valves. They are easy to install in any location on the vessel, allowing for easy maintenance of the heater. The water or oil can be purged through the drain valve allowing for maintenance on the heating elements. Calcium deposits and other residues can build up on heating elements. These require cleaning several times a month. Circulation heaters also come with horizontal or vertical mounting, depending on your application. Skid mounted vessels are used in oil heating industries that require mobility. WATTCO™ electric heaters are also available in different terminal boxes. These include moisture resistant or explosion proof terminal boxes for hazardous environments. WATTCO™ circulation heaters are an exceptional choice for heating process liquids. They use materials that are resistant when heating corrosive mediums.
Circulation heaters are also used when heating closed loop systems. These can require high temperatures of up to 1000℉. These applications use large flange heating vessels that contain the gas and heating it efficiently. It requires low maintenance and provides excellent heat transfer.
Oil and Gas companies use circulation heaters in heating oils. Electric heaters assist them in modifying the viscosity levels of their heating oils. Crude oil enters an inlet of the vessel at a cool temperature. The circulation heater reheats the oil. The oil then exits the outlet at a temperature more convenient for flow as it travels from one end of the transport pipe to the other. Hydraulic fluid can also be heated using this electric heater for heat transfer purposes. It also provides freeze protection in cooler climates. This is crucial because winter temperatures can damage the fluid. Immersion heaters are widely used in a variety of industries. Particularly the oil and pipeline sector for several different purposes. These industrial heaters are specifically designed so that oil, water, viscous materials, gases, solvents and other different process mixtures can be heated in direct contact with each other. This allows the heat to be generated within a single enclosure or solution, and so hundred percent efficiency can be achieved. Get a quote for a circulation heater today.

Flanged heaters are commonly used in many chemical, petroleum and water based applications. Consisting normally of an ANSI rated flange with several hairpin elements or bugle tubular elements extending from the face of the flange, this electric heater uses direct heat application to the liquid medium. 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 control panel that cycles and maintains the desired target temperature. Often a high limit sensor is also used to help protect liquid mediums from over heating and, offers protection to the flange heater as well.

Wattco flanged heaters allow the flexibility of using many different alloys to help resist corrosion and maintain life longevity of the flanged heating element Steel flanges are typically used for lubricant oils, heavy and light oils, waxes as well as mildly corrosive liquids and low flow gas heating. Steel flanges can also be found in immersion heaters for water tanks. These flanged heaters are used to process soap and detergent solutions as well as demineralized or deionized water. Stainless steel flanged heaters 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 in a flanged heater 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.
Flanged heaters use bent tubular elements that are brazed or welded onto a flange. Extra wiring boxes in which the electrical connections are fixed are provided with it. Some heaters have already been prefixed into flanges, but others can be welded on matching flanges that are mounted on a nozzle or tank wall. Wattco offers flanged heaters in varying kilowatts ratings, voltages, temperature ranges, sheath materials and so on.
Flanged immersion heaters are one of the most widely used industrial heater options in the oil sector. Compared to other oil heaters, they are easier to install, are specifically designed for use in pressurized vessels and more manageable. Typical applications include preheating different grades of oil, cleaning tanks and heat transfer.
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.
