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.

Flanged Heater Uses

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 welding techniques on matching flanges that are mounted on a nozzle or tank wall.

• Instant Heating: Flanged heaters generate heat faster and evenly for liquids, gases, and viscous fluids and are used in chemical processing and petrochemicals.
• Durability: It works under high pressure and harsh environments and is used in industries like oil and gas, water treatment, and power generation.
• Versatility: Heats all media, like water, oil, chemicals, and gases. It is customizable to the required flanged size and client needs.
• Energy Efficiency: Targeted heating and integration with a modern control system reduces energy consumption.
• Safety: Embedded with safety measures like temperature control, over-temperature protection, pressure management, and operating safe during critical environments.
• Low Maintenance: These heaters are easy to install and replace, reducing downtime and operational costs.

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.
