Process electric tank heaters have several advantages in storage tank applications due to the precise control of temperature and heat distribution required for liquid storage conditions. Each industrial heater solution is designed for the specific application and optimized to ensure high performance results. We take into account temperatures, flows and mixing, viscosity of the fluid, corrosive nature of the fluid, tank insulation and the overall operating conditions and project requirements.
Durex engineers and manufactures a variety of standard designs as well as customized solutions for a variety of tank heating applications including open or closed tanks, outdoor or indoor installations, as well as underground tanks, pressure vessels, and even railroad tank cars and over the road trailer tanks.
Direct Heat / Direct Immersion Tank Heaters
Screw Plug Immersion Heaters - Ideal for economical and reliable heating for a large variety of small volume tanks. Constructed of rugged hairpin tubular elements brazed or welded into NPT pipe fittings, these heaters are easily screwed into a threaded coupling in the tank wall or vessel. Hundreds of industry standard designs available.
Flange Immersion Heaters – Flange immersion heaters are used for higher power, larger tank heating requirements. Constructed similar to screw plug heaters, with hairpin bent tubular heater elements brazed or welded into ANSI standard flanges or plate flanges of various shapes and sizes. Typically used for large volume, high power and/or higher-pressure applications requiring a flange tank or pipe connections such as found in the chemical processing or oil & gas industries.
Over The Side Immersion Heaters - Consisting of multiple tubular heater elements, these electric heaters are designed for installation at the top of the storage tank or through an access port with the heated portion directly immersed along the side or at the bottom of the tank. These heaters are adaptable to the tank shape and easily removed for maintenance or use in temporary heating applications.
Suction Heaters – A hybrid of an immersion, inline circulation and dry well heaters, this is typically used in oil storage tanks where the user does not want to heat the entire tank contents. Essentially an “on demand” heater, a large pump creates “suction” and draws the cold oil into and through the suction heater, and out of an outlet port outside of the tank. Contact Durex for more information.
Inline Circulation Heaters – These electric industrial heaters are ideal for fluids that require constant mixing in tanks without mechanical mixers or when it is impractical to install an immersion heater into an existing tank. Circulation pumps move the fluid from the tank through the heater and back into the tank to set up circulation currents.
Indirect Immersion Tank Heating
Dry Well Heaters– When draining a storage tank for heater removal and servicing is not feasible, a dry well heater is a perfect solution. A screw plug or flange immersion heater is fitted into a pressure-tight bayonet pipe (closed end protection tube) and inserted into the bottom of a tank. This isolates the heating elements and facilitates easy removal of the heaters.
Process Tank Heating Systems
Process heating systems consist of skid- or frame-mounted circulation heaters, process air heaters, or DFX cast circulation heaters with or without an integrated control panel and instrumentation. Process heater systems allow for easy field installation at the job site enabling quick hook up to power as well as process piping.
Advantages of Using an Industrial Heating System
Process heaters are integrated heating & control systems that provide plug-n-play heating solutions. These process tank-heating systems are cost effective and save time during installation, allowing you to install the entire unit instead of individual components. Durex Industries is the single-point of responsibility for engineering, manufacturing & delivering the entire project.
