Industrial immersion heaters are a fast and efficient way of heating up various liquid solutions in processing equipment, large tanks and containers in many industries. Heating up liquids using direct heat transfer allows for the liquid medium to quickly reach the desired temperature using electric heaters such as flanged heaters, screw plug heaters, over the side heaters or circulation heaters. This application is commonly used in chemical processes, large petrochemical containers as well as large water containers that require fast heat up time. With minimal maintenance requirements, immersion heaters are an excellent solution to rapid heating in almost any industrial environment.

 

Flanged heaters have the ability to hold multiple hairpin elements that can be mounted onto the side of a metal tank. Its versatility allows it to offer up to 750 KW of power on a single unit. Among its various uses include utility companies, defense contractors, petrochemical researchers and boiler manufacturers.


 

Circulation heaters (or In Line Heaters) use immersion heaters such as flanged heaters or screw plug heaters within a vessel chamber to heat up liquids from an inlet and expels the heated liquid through an outlet using the force of a pump to allow easy circulation. The circuit of running liquid is then reheated to reach a target temperature. It is often referred to as the most efficient use of electric heating as heat is initially applied to liquid at ambient temperature but then recirculated at an elevated temperature that does not require as much energy to reach your target temperature. The use of insulation around piping and the tank itself allows the heat to be contained. The circulation vessel is often reinforced with high quality insulation that helps prevent heat loss. Coupled with the use of a high quality alloy that prevents heat loss (high grade stainless steel) the unit is a complete system that allows users to use thermocouples, RTD temperature sensors or standard mechanical thermostats to maintain liquids at optimum temperatures. Safety sensors are also available such as high temperature sensors to help prevent excessive heat or over temperatures. This protects both the liquid you are heating as well as protection to your flanged heater.


 

The use of electric immersion heaters has been more popular in the past several decades as rising costs of fuels force individuals to select a more cost efficient way of heating their applications. Ecologically conscientious groups have long advocated for cleaner energies to help save the environment. Electric heating has been known to be the cleanest form of heating leaving no residual discharge and provides immediate heat transfer to any medium. Over the side heaters are used to heat up larger containers of liquid that have openings.

Immersion heaters are often available with several different ranges of temperatures that can be fine tuned for extreme accuracy. As such, very tight and efficient control can be maintained which has a positive effect on the performance of the industrial plant. Along with this, several mounting options can be also be availed which further facilitate processes. Examples include screw plug connections, over the side designs and flanges. There are several options for piping as well such as flanged, welded or threaded.

Circulation Heaters also known as "in line heaters" use steel, stainless steel, titanium flanged immersion heaters in many applications. Lube oil and waste oil applications often use steel for circulation heaters as it is fairly inexpensive compared to stainless steel counterpart. In line heaters flowing water use stainless steel, admired for its anti corrosive qualities. Both applications involve using a pump that flows the liquid through a closed pipe circuit (IE. water or glycol solution) that is reheated. A major consideration for this application is viscosity. Heat that is generated by the oil heater allows the liquid to be viscous enough to pass through the circuit of pipes. Circulation heaters come in a range of watt densities that are specifically designed for the medium that is heated. The required wattage to heat the oil or water is highly correlated to the flow rate (in GPM). The oil or water enters through an inlet (the inlet closest to the flange heater) and gets heat applied to it as it flows within a vessel chamber and exits the outlet nozzle (or flange) where it circulates throughout the piping circuit. Insulation is often required for vessels in order to preserve the heat to be applied within the vessel. Efficient heat application can often reduce unnecessary costs through heat loss. Digital thermocouple probes or RTDs, can be  used with the electric immersion heater to maintain the oil or water at the preferred temperature. Many applications use liquids with low flash point and, require explosion proof housing (NEMA 7) to avoid potential mishaps.

 

Other useful features found with circulation heaters are drain valves.  They can be installed in any location on the vessel and allow for easy maintenance of the heater. The water or oil can be purged through the drain valve allowing for maintenance on the elements. Calcium deposits and other residue can be found on elements and should be cleaned several times a month. Inline heaters also come with the choice of horizontal or vertical mounting depending on your application. Skid mounted vessels are used in oil heating industries that require mobility. Wattco heaters are also available in moisture resistant terminal boxes or explosion proof terminal boxes for hazardous environments. Wattco in line heaters are an exceptional choice for heating process liquids, non corrosive to the materials of construction. In line gas heaters are also used when heating closed loop systems that require high temperatures of up to 1000 deg F. These applications use large flanged vessels that contain the gas and heat it up in containment most efficiently requiring low maintenance and excellent heat transfer.

Oil and Gas companies have specifically used circulation heaters to assist them in the process of modifying viscosity levels of their heating oils . Crude oil enters an inlet of the vessel at a cool temperature and 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 immersion heater for heat transfer purposes, and to resist cooler climates as winter temperatures need to be avoided. Immersion heaters are widely used in a variety of industries particularly the oil and pipeline sector for several different purposes. These 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.

In line heaters (a.k.a circulation heaters) are ideal for processing fluid, including hazardous liquids, that requires intermediate heating while maintaining a flow rate. Instead of stripping the heat from another source as it would for a heat exchanger, an In line heater simply transfers the heat generated from electrical power into the target fluid. The main characteristics of the in line heater are for efficient heat transfer, the easiness to install and to maintain, and its high range compatibility with the current standard industrial piping. Applications such as waste oil, steam and water processing can use in line heaters in order to regulate and control the temperature, but also to maintain the fluid viscosity. An improper liquid viscosity could gradually slow down the overall processing time of the production. In addition, the product’s final yield and purity could also be affected by a slight deviation of the viscosity. To avoid this type of problem, a heater inline is used to heat the fluid so that at the proper temperature, the viscosity remains unchanged and at the same time to process the medium at a desirable steady flow rate. To control the liquid flow rate of the heater, the wattage can be manipulated and regulated to obtain the desired temperature (in other words, the flow rate is directly proportional to the temperature/liquid viscosity).

An in line heater is composed of an immersion heater covered by an anti-corrosion metallic vessel chamber. This casing is mainly used for insulation to prevent heat loss in the circulation system. Heat loss is not only inefficient in terms of energy usage but it would also cause unnecessary operation expenses. A pump unit is used to transport the inlet fluid into the circulation system. The fluid is then circulated and reheated in a closed loop circuit around the immersion heater continuously until the desired temperature (up to 1000°F) is reached. The heating medium will then flow out of the outlet nozzle at a fixed flow rate determined by the temperature control mechanism.

Tools such as the RTDs and digital thermocouples can be used to precisely control the temperature of the heating system. For extra protection, optional components such as moisture resistant or explosion proof housing are available for special applications. Drain valves are also available on the circulation heater to facilitate the procedure with the system maintenance, whereas the leftover fluid or residues (such as water or Calcium) can be easily removed from the equipment. Special mounting options are available for the target application’s mobility requirement. The flange immersion heater inside the circulation unit can be customized by WATTCO™’s manufacturing depending on the chemical and physical properties of the target fluid. Other customization options, such as the equipment orientation (vertical or horizontal) or flange type, are also available to consider for your target application.

There is a large variety of immersion heaters available in the market which can even be tailored to meet specific needs of an oil plant. The offered products can be used in a variety of applications that feature high pressure ranges or are executed in hazardous regions. Generally, whenever an immersion heater is used for heating, it is usually immersed in the solution which has to be heated. As such, the heating elements are often covered by a sheath so that they remain protected.

Inline heaters comprise of heating elements that are mounted in a rounded tube. Often, the flanged heater is thermally insulated by either the side or inline operation so that the efficiency of the heating process can be increased. This is particularly done when a flowing medium has to be heated. Almost all inline heaters use  thermocouple sensors that can be integrated with any control to manage the temperature range. Different applications call for varying options for terminal enclosure, sheath material, flanged connections, and temperature ranges. Several mounting options are also available such as integral mounting utilizing SCRs and remote mounting which uses contactor control panels.
 
A vessel heater is manufactured as a packaged unit which contains several components such as heating element, chamber, thermostat, sensors, insulated material, brackets for mounting and electrical connections. The efficiency of this heater is high as all heat is produced within the substance or vessel. The operation is fast and executed in a short time. The heat generated is evenly distributed throughout the substance.
 
Many applications make use of indusrial heaters. The most common of these are heating oils, corrosive solutions, water cooled engines, oil sump heaters, process kettles, blending mills, molding dies, steam superheating and preheating purposes such as viscosity pumping and oil delivery to burners.

Flanged industrial immersion 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 controller 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 flanged heater as well.


Wattco flanged immersion heaters allow the flexibility of using many different alloys to help resist corrosion and maintain life longevity of the flanged heater. Steel flanges are typically used for lubricant oils, heavy and light oils, waxes as well as mildly corrosive liquids and low flow gas heating. Process water, soap and detergent solutions as well as demineralised or deionized water applications often use steel flanges. Stainless steel flanged heating elements 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 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.

Just like screw plug heaters, flanged immersion 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 immersion heaters in varying kilowatts ratings, voltages, temperature ranges, sheath materials and so on.
 
Flanged immersion heaters are one of the most widely used heating options in the oil sector. Compared to other 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.

 

Screw Plug heaters from WATTCO™ consist of hairpin tubular elements that are brazed or welded into a machined pipe thread fitting, (normally an NPT fitting for North American standards) which are then screwed directly through a threaded coupling in the tank wall or vessel, or installed in pipe. Screw plug heaters are an easy way to heat up solutions in smaller containers that also require controls. Mechanical thermostats or Digital controllers can be used with these immersion heaters to help reach target temperatures with great accuracy meeting your project objectives. Additional thermowells can be installed for high limit temperature probes to help protect your liquid and processes.



Screw Plug heaters from WATTCO™ are used for heating gases and liquids in tanks or vessels. These elements are designed to be immersed in liquid so that heat transfer will occur at a rapid rate, enabling quick heat up times. Typical uses include the food and beverage industry, laboratory clinics, applications involving hydraulic oils and lubricants as well as more sophisticated uses such as heating up flammable liquids or gases which require explosion proof housing.

WATTCO™ Pipe Heaters are especially constructed to fit inside standard 2 or 3” schedule 40 NPS pipes. Specifically designed to fit in tank applications that require extremely low watt densities such as waxes, thick liquids such as tar, molasses and corrosive mediums. Wattco pipe heaters do not come in contact with the liquid medium. Rather the indirect heating from element to pipe is used to heat liquid sources. This provides easy maintenance as the tank does not need to be emptied out if heater needs to be replaced.

 

Designed to withstand high heat environments, Wattco pipe heaters are an excellent choice to use with heavy bunker fuel oils, corrosive liquids and liquids with high viscosity. Wattco pipe heaters can use flanged heaters, screw plug heaters as well as resistance coil heaters (open coil heaters).

 

Pipe heaters use supportive ceramics resistant to high thermal heat that provide mechanical support to coils. Thermocouples can also be used to relay temperature readings to a digital controller that helps regulate the heat intensity. Steel pipes can be used for their thermal transfer properties and their corrosion resistant properties to many petrochemical solutions.  Open coils are the most efficient type of electric heating while at the same time being the most economically feasible for most heating applications.

Over the Side Heaters are a popular 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 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 meet the budget of any project manager. These 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 controller, 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 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 heater is usually made from steel, copper, cast alloy and titanium. A coating of fluoropolymer or quartz is 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.

Wattco offers boiler heaters that suit many different sizes and dimensions that customers need. If a boiler ahs a flanged heater that need to be replaced, Wattco can replicate the model you currently have from practically any manufacturer and have your boiler system up and running in a matter of hours. Boiler heaters come in a variety of different flange sizes and lengths. The two common models are rounded flanges and square flanges. The lengths of the boiler heater is highly correlated to the length that is available within your boiler. If all the major variables are known (ie. Wattage, Voltage, Length and Flange size), Wattco can replicate the model you have in no time.

Boilers are used in many facilities for comfort heating, laundry services, and kitchen services. The nature of the facility's operations will indicate whether the boiler system is steam generating or if hot water system is used. Hot water systems typically heat up water up to 230 degrees Farenehit. The operating pressure for hot water systems is approximately 30 psi to 125 psig (hydrostatic).

There are many different types of steam and hot water boilers. Low pressure steam boilers are limited to 15 psig are are predominantly used in common heating practices such as comfort heating. High pressure boilers are used for more intense applications and can have up to 1000 psig.

Electric boilers are extremely popular as they are considered the most efficient method of heating water or steam and, the are clean, quiet and easy to install.Because there is no carbon emissions, electric boilers have very low maintenance costs with easily replaceable electric heating element (flange heaters). Government regulated bodies are enforcing more often, the use of electric boilers to meet carbon emission standards that are being enforced as a result of the carbon footprints of fossile fuels. In areas where the cost of electric power is favorable, electric heating is considered the best choice as it offers power ranges of 5KW up to 3,000 KW of output power.
