Petrochemicals often require certain temperatures in order to maintain its viscosity in process applications as well as in harsh external environments.
Oil and Gas Industry
Flanged heaters are often chosen in order to apply a relatively moderate heat source that can penetrate the heavy lubricant evenly across the containment. Bitumen often uses flanged heaters to help with the extraction process in the oil industry.Circulation heaters are used when circuits of flowing liquid exist and users are looking for minimal (or gradual) heat applications. The temperature of the liquid starts off at ambient temperature but the residual heat that already exists in a well insulated circuit is assisted with bursts of gradual cyclical heat from a heat source: the flanged immersion heater.
Immersion heaters are one of the most important sources to complete numerous heating projects. Different industries use special types of liquids, kept in containers, processing equipment and large tanks, to heat fluids. Through direct heating, companies are able to quickly attain the required temperature- whether they are using pipe heaters, circulation, over the side heaters or any other kind. They have a lot of importance in almost every industry however, petrochemical, chemical and process industry where companies need fast heating up time. Industrial immersion heaters are also helpful in keeping liquid below freezing temperature, especially in winter where, fluids freeze faster and maintaining their condition becomes difficult.
Flanged immersion heaters are useful for water-based, chemical and petroleum industries to direct transfer heat to the liquid. These heaters are constructed to maintain temperature of fluids through their ANSI rated flange provided with bugle tubular elements or many hairpin elements. A thermowell is available within the heaters to assist RTD, basic mechanical thermostat or thermocouple to communicate temperature readings to the digital controller, which is responsible to maintain the required temperature.
Screw plug Immersion heaters are equipped with hairpin tubular elements that are welded or brazed into pipe thread fitting and then connected with a threaded coupling of vessel or tank wall. These heaters are the easiest source to heat up liquids in small containers. Digital controllers or mechanical thermostats are normally used with these industrial immersion heaters to sustain the target temperature with effectiveness and accuracy.
Pipe heaters (drywell heaters) are designed to easily fit in standardized two or three inches schedule 40 NPS measured pipes so that they can properly provide low watt densities for mediums like wax, think fluids like corrosive mediums, tar and molasses. These heaters do not directly heat mediums instead, they use the path from pipe to medium for heating. The process simplifies its maintenance because companies don’t have to empty them while replacing. Pipe heaters are actually manufactured to withstand in extreme heat and therefore, can be easily used to heat corrosive liquids, fluids with higher viscosity and heavy bunker fuel oils.
Over the side immersion heaters are famous for practical, commercial and economic purposes. Provided with water-resistant terminal housing, these heaters are available in different sizes and shapes to compliment the requirements of the industries. They can be manufactured with a thermowell and multiple tubular elements that hold the temperature probe. Over the side heaters are capable of meeting standard economic feasibility of every project manager. So, they can be used in almost all industries according to the nature of use.
Using precise instrumentation such as a thermocouple or an RTD, users can often reach the temperature required with efficient use of clean energy while achieving their goals. Control panels are also used with high limit controllers to help prevent higher temperatures that could result from caking material that stick onto the heating elements. Low watt densities assist with the preservation of heating elements but a good control that shuts off the elements in the presence of high temperatures is an effective means to preserve both the heated medium as well as the heat source: your WATTCO flanged heaters.
An excellent choice for open tanks. These are custom designed for your specific tank dimensions with a digital control panel (or a mechanical thermostat) for accurate temperature control. The mobility of these units allow for users to use one heater for multiple tanks if required.
