Circulation Heaters


Product Description

Fluent In-line Heater

  • Small, lightweight, robust heater construction
  • High watt density, low mass heater
  • Integrated solution that replaces multiple components
  • Internal thermocouple for high limit control

Optimax Heat Exchanger

  • Realize improved heat transfer efficiency with Watlow’s EFD (enhanced fluid dynamics) technology
  • Reduce overall footprint up to 50 percent
  • Achieve world-class pressure drop performance
  • ANSI compatible or similar, 3 through 48 sizes
  • Power duty up to 3 megawatts

Starflow Circulation Heaters

  • Small diameter heater for quicker response time
  • Internal starwound element provides fast, efficient heating
  • Sheathed element to heat in clean or impure streams
  • Flexibility in configurations to adapt to any process
  • Minimal flow restriction results in low pressure loss

Watrod and Firebar Circulation Heaters

  • Catalog screw plug and flange part numbers provides a wide selection of WATROD and FIREBAR elements to meet specific application requirements
  • ANSI B16.5 Class 150 on 4 or 6 inch FIREBAR element flanges and 3 to 14 inch WATROD element flanges meets recognized agency standards
  • Compacted MgO insulation filled elements maximizes dielectric strength, heat transfer and life
  • Heavy-guage steel jacket (shroud) protects thermal insulation and heating vessel and comes with protective primer coating
  • 1 inch (25 mm) thermal insulation rated to 750°F (400°C) reduces heat loss from the vessel
