Description

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

Watlow flange immersion heaters feature Watlow's industry leading WATROD® or FIREBAR® heating elements. These elements can be brazed, staked, or welded to a four- or six-bolt flange and mounted directly to a mating flange that is welded to a tank wall nozzle.

Watlow flange 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.

By using WATROD® or FIREBAR® heating elements, Watlow flange immersion heaters are rated up to one megawatt and can generate watt densities up to 100 W/in2 and sheath temperatures up to 1600°F (depending upon sheath material).

Watlow flange immersion heaters are available with a wide array of options to tailor each heater to your particular application. To provide process temperature control, Watlow offers optional single pole, single throw (SPST) and double pole, single throw (DPST) thermostats. Additionally, there are a number of terminal enclosures available to protect wiring from moisture, corrosion or to provide an air-insulating barrier between the flange and terminal enclosure. Type J or K thermocouples, which offer more accurate sensing of process and/or sheath temperatures, may be inserted into the thermowell or attached to the heater's sheath. For forced circulation applications, baffles can be arranged on the heating element bundle to enhance and/or modify fluid or gas flow for better heat transfer. A number of material and size options are also available.

Applications for the Watlow Flange Immersion Heater

  • Industrial water rinse tanks
  • Hydraulic oil, crude, asphalt
  • Lubricating oils at API specified watt densities
  • Vapor Degreasers
  • Paraffin
  • Caustic Solutions
  • Air and gas flow
  • Chemical Baths
