Tubular and Process Assemblies Watlow flange heaters are easy to install and maintain. Designed for heating liquids and gases in tanks and pressure vessels, flange immersion heaters are ideal for applications requiring higher kilowatts. Watlow flange heaters are made with WATROD or FIREBAR® tubular elements brazed or welded to a flange. Stock flange heaters are equipped with a general purpose (NEMA 1) terminal enclosure. Flange 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 petroleumbased liquid heating applications. Performance Capabilities • Watt densities to 100 W/in2 (15.5 W/cm2) • Wattages to one megawatt • UL® and CSA component recognition to 480VÅ(ac) and 600VÅ(ac) respectively • Incoloy® sheath temperatures to 1600°F (870°C) • Passivated 316 stainless steel sheath temperatures to 1200°F (650°C) • 304 stainless steel sheath temperatures to 1200°F (650°C) • Steel sheath temperatures to 750°F (400°C) • Copper sheath temperatures to 350°F (175°C)

Features and Benefits • ANSI and ANSI compatible 2, 21⁄2, 3, 4, 5, 6, 8, 10, 12 and 14 inch flanges provide appropriate heater size-to-application and fit. • Flange sizes up to 24 inches available on made-to-order units. • Element sheath and flange materials to meet application needs. • Integral thermowells provide convenient temperature sensor insertion and replacement without draining the fluid being heated. • A standard, general purpose (NEMA 1) terminal enclosure offers easy access to wiring. • Element support(s) provide proper element spacing to maximizing heater performance and life.

• To facilitate lifting, drilled and tapped holes come supplied for eye bolts on 10 inch and larger flange heaters. • All units are inspected and/or tested to ensure element-toflange pressure seals do not leak. • Four or six inch FIREBAR flange heaters pack more kilowatts in smaller bundles—in liquid immersion applications, a conventional 10 inch round tubular element flange can be replaced with a six inch FIREBAR flange. • WATROD hairpins are repressed (recompacted) to maintain MgO density, dielectric strength, heat transfer and life. • Branch circuits meet NEC with 48 amps per circuit maximum. • UL® and CSA component recognition under file numbers E52951 and 31388 respectively.

Thermocouples 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 inch (3050 mm) leads (longer lead lengths available). Unless otherwise specified, thermocouples are supplied with temperature ranges detailed on the Thermocouple Types chart. Using a thermocouple requires an appropriate temperature and power control. These must be purchased separately. Watlow offers a wide variety of temperature and power controls to meet virtually all applications. Temperature controls can be configured to accept process variable inputs, too. Wattages and Voltages Watlow routinely supplies flange immersion heaters with 240 to 480VÅ(ac) as well as wattages from 150 watts to one megawatt. If

Thermostats 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. For details and ordering information, refer to Thermostats on pages 423 to 425. Please verify that the thermostat’s sensing bulb O.D. is compatible with the flange heater’s thermowell I.D.

Consult your 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.

Tubular and Process Assemblies Flange Immersion Heaters Application Hints • Select the recommended heating element sheath material and watt density for the substance being heated. Use the Supplemental Applications Chart on pages 263 to 266. If unable to determine the correct heating element sheath material and type, consult your Watlow representative. • Extend the element no-heat section completely into the fluid being heated to help prevent premature heater failure. See accompanying illustration for proper no-heat section placement. • Locate flange heater low in the tank, but above the sludge level.

Flange Immersion Heater

No-Heat Section

• Choose a FIREBAR element when your application requires a smaller system package or lower watt density. • Ensure wiring integrity by keeping terminal enclosure temperature below 400°F (205°C). • Keep electrical connections clean, dry and tight. • Minimize problems associated with low liquid level conditions by

using low liquid level sensor or sheath temperature high-limit control. • Periodically remove the flange assembly to inspect and clean the heating element(s). This preventive maintenance will reduce premature failure and optimize heater performance. • Refer to the Installation and Maintenance Instructions for correct orientation of FIREBAR elements. This is important in air applications with customer supplied circulation tanks. Correct element orientation to flow minimizes pressure drop, increases buoyancy force and heater performance.

Flange Immersion Heater Base Code Number➀ (Includes general purpose enclosure without thermostat) Terminal Enclosure Type S = General purpose (NEMA 1) W = Moisture resistant (NEMA 4) E = Explosion resistant (NEMA 7) E/W = Explosion/moisture resistant (NEMA 7/4) Thermostatb Thermocouplec J = Type J K = Type K a Flange immersion heaters are supplied with a standard, general purpose (NEMA 1) terminal enclosure. A thermostat will not fit the standard general purpose terminal enclosure on 2, 21⁄2 and 3 inch flange sizes. b Code numbers are shown on the Thermostat stock chart on page 425. Check the temperature sensing bulb O.D. to be certain it will fit into the thermowell’s I.D. c Specify Type J or K thermocouple. If overtemp thermocouple specify orientation horizontal, vertical up or vertical down.

How to Order To order a stock flange heater, please specify: • Watlow code number • Flange size and material • Volts/watts • Phase • Options • Quantity If the flange immersion heater is to be configured with options, add the suffix letter(s) to the base flange heater code number, as indicated on the Build-a-Code chart. If our stock units do not meet your application needs, Watlow will make-to-order.

For made-to-order units please specify: • Application, including media heated, flow rate, pressure, and process operating temperatures • Volts/watts • Watt density • Phase • Number of circuits • Number of heating elements • Element diameter (WATROD only) • Immersed (‘B’ dimension) length • Flange size, rating and material • No-heat section below the flange • Terminal enclosure type • Options • Quantity

Availability Stock: Same day shipment Assembly Stock: Five to seven working days Modified Stock➂: Five to seven working days Standard: 10 working days Made-to-Order: Five to seven weeks Options, complexity and quantity may affect availability and lead times. Consult factory.

➂ Stock or Assembly Stock units with catalog options.
