Watlow's WATROD tubular heater elements and flat FIREBAR elements are designed primarily for direct immersion in liquids such as water, oils, solvents and process solutions, molten materials as well as air and gases. By generating all the heat within the liquid or process, these heaters are virtually 100 percent energy efficient. (read more)

Heatrex Tubular Heaters provide a highly efficient, reliable and low cost means of rapidly supplying heat directly to air, metals and various types of liquids, depending on the application. (read more)

The most versatile of all electric heating elements, the tubular heater is capable of being formed into virtually any configuration. The basic design consists of a helical coil of nickel-chromium resistance wire precisely centered in a metal sheath. This coil is surrounded by magnesium oxide powder which is vibration loaded to insure even density throughout the length of the heater. (read more)

Heatrex Finned Tubular Heaters are used for natural or forced convection space heating and industrial process air heating. Sheath temperatures are suitable for drying, heat treating, annealing, curing in ovens or dryers and air heating in ducts. (read more)

Heatrex Finned Tubular Duct Heaters are engineered for lower temperature industrial process heating and re-circulating ovens at temperatures of 600° and below. (read more)

Custom Rigid Tubular Heaters can be installed as new or replacement equipment for metal sheathed style tubular units that have higher watt density designs that result in coking of the product. These heaters can be installed as direct immersion units in tanks and vats to maintain process temperatures during operation, plant maintenance shutdowns or increase oil temperatures prior to startups.
