Watlow Flanged Immersion Heaters

3"- 6" Flange Heaters with Baffles from WATLOW and Flow Factor

Watlow flanged immersion heaters are easy to install and maintain. Designed for heating liquids and gases in tanks and pressure vessels, ANSI flanged immersion heaters are ideal for applications requiring higher kilowatts.

Watlow flanged immersion heaters are made with WATROD or FIREBAR tubular elements brazed or welded to a flange. Stock flange heaters are equipped with a general purpose terminal enclosure.

Watlow Flanged immersion heaters, with FIREBAR elements, also answer the need for liquid immersion applications requiring high kilowatts in small tanks. The FIREBAR element's unique flat surface geometry packs more power in a smaller bundle, with lower watt density, making it especially well-suited for petroleum-based liquid heating applications.

Features and Benefits:

UL® and CSA component recognition.
ANSI and ANSI compatible 2, 2½, 3 thru 48 inch flanges.
Integral thermowells provide convenient temperature sensor insertion       and replacement without draining the fluid being heated.
Standard, general purpose terminal enclosure for easy access to wiring.
All units are inspected and/or tested to ensure element-to-flange pressure seals do not leak.


Alloy 800 Material = 1600º Max. Temp and 100 Watt Density Max.
Stainless Steel Material = 1200º Max. Temp and 100 Watt Density Max.
Steel Material = 750º Max. Temp and 100 Watt Density Max.

Typical Applications
Water: Deionized Demineralized Clean Potable Process Industrial water rinse tanks Vapor degreasers Hydraulic oil, crude, asphalt Lubricating oils at API specified watt densities Air and gas flow Caustic solutions Chemical baths Process air equipment Boiler equipment Freeze protection of any fluid Anti-freeze (glycol) solutions Paraffin

Terminal Enclosures
General purpose terminal enclosures, without thermostats, are standard on all flange immersion heaters. Optional terminal enclosures include:
• General purpose with a single or double pole thermostat.
• Moisture resistant. Available with or without a single or double pole thermostat.
• Corrosion resistant. Available with or without a single or double pole thermostat.
• Explosion resistant Class 1, Div. 1 and 2, Groups B, C and D, T1-T6. Available with or without a single or double pole thermostat.
• Explosion/moisture resistant combinations. Available with or without a single or double pole thermostat.

Stand-off Terminal Enclosures
Stand-off terminal enclosures provide an air-insulating barrier between the flange and terminal enclosure by mounting the terminations and wiring away from the flange. Stand-off terminal enclosures are recommended whenever a process operating temperature exceeds 210°F (100°C). This helps minimize terminal enclosure temperatures.

Certified Enclosures
CSA, ATEX, IECEx or PESO certified enclosures protect wiring in hazardous gas environments.

ASME Pressure Vessel Code Welding
Flange assemblies can be provided with an ASME Section VIII, Div. I pressure vessel stamp upon request.

To provide process temperature control, Watlow offers optional single pole, single throw (SPST) and double pole, single throw (DPST) thermostats.
Unless otherwise specified, thermostats are mounted inside the terminal enclosure. Please verify that the thermostat’s sensing bulb outside diameter is compatible with the flange heater’s thermowell inside diameter.

ASTM Type J or K thermocouples offer more accurate sensing of process and/or sheath temperatures. A thermocouple may be inserted into the thermowell or attached to the heater’s sheath.
Thermocouples are supplied with 120 in. (3050 mm) leads (longer lead lengths available). Unless otherwise specified, thermocouples are supplied with temperature ranges.
Using a thermocouple requires an appropriate temperature and power controller. These must be purchased separately. Watlow offers a wide variety of temperature and power controllers to meet virtually all applications. Temperature controllers can be configured to accept process variable inputs, too. Contact a Watlow representative for details.
To order, specify Type J or K thermocouple and lead length. Indicate if the thermocouple is for process temperature sensing or heater sheath high-limit protection. Please specify if the flange heater will be mounted vertical or horizontal in the tank. If vertical, specify if the housing is on top or bottom.
If the flange heater is part of an in-line circulation heating application, indicate flow direction relative to the heater’s enclosure.F

Wattages and Voltages
Watlow routinely supplies flange immersion heaters with 240 to 480VAC as well as wattages from 150 watts to one megawatt.
If required, Watlow will make heaters with voltage up to 600VAC and wattage beyond one megawatt.

Watlow FIREBAR® Heaters from Flow Factor

FIREBAR® Single/Double-Ended Heaters by Watlow

Get a Quote HERE!

Watlow FIREBAR heating elements provide added heating performance over standard round tubular heating elements—especially for immersion applications in petroleum-based liquids requiring high kilowatts. 
The FIREBAR's unique flat surface geometry packs more power in shorter elements and assemblies, along with a host of other performance improvements. These include:

-Minimizing coking and fluid degrading

-Enhancing the flow of fluid past the element's surface to carry heat from the sheath

-Improving heat transfer with a significantly larger boundary layer allowing much more liquid     to flow up and across the sheath's surface

Watlow FIREBAR elements are available in single- and double-ended constructions with one inch or 5⁄8 inch heights. These two configuration variables make it possible to use FIREBAR elements instead of round tubular elements in virtually all applications.

70 percent greater surface area per linear inch compared to a 0.430 in. (11 mm) diameter round tubular heater

Compacted MgO insulation maximizes thermal conductivity and dielectric strength

Precision wound nickel-chromium resistance wires

0.040 in. (1 mm) thick MgO walls transfer heat more efficiently

Three resistance coil design readily adapts to a variety of electrical sources and wattages outputs
