WATROD™ AND FIREBAR® SCREW PLUG IMMERSION HEATERS
IDEAL FOR DIRECT IMMERSION HEATING OF LIQUIDS
Screw plug immersion heaters are ideal for direct immersion heating of liquids, including all types of oils and heat transfer solutions.
Available in a variety of sizes, Watlow screw plug immersion heaters feature both WATROD round and FIREBAR flat tubular elements.
Heating elements are hairpin bent and either welded or brazed into the screw plug, depending on element sheath and plug material compatibility.
General purpose terminal enclosures are standard with optional moisture resistant, explosion resistant and explosion/moisture resistant enclosures available to meet specific application needs.
Optional thermostats provide convenient process temperature regulation to the screw plug immersion heater.
- UL® and CSA component recognition
- A variety of element sheath and screw plug materials to meet your application needs
- Integral thermowells provide convenient temperature sensor insertion and replacement without draining the fluid being heated
- Terminal enclosures provide ability to be rotated to simplify connection with existing conduits
- Welding or brazing WATROD and FIREBAR elements to the screw plug for a pressure tight seal

SILICONE RUBBER HEATERS
IMPROVE HEAT TRANSFER, SPEED WARM UPS AND DECREASE WATTAGE REQUIREMENTS
Watlow silicone rubber heaters are rugged, yet thin, lightweight and flexible. Use of these heaters is limited only by the imagination. Heat can be put where it is needed. These silicone heaters improve heat transfer, speed warm ups, and decrease wattage requirements.
Fiberglass-reinforced silicone rubber gives the heater dimensional stability without sacrificing flexibility. Because very little material separates the element from the part, heat transfer is rapid and efficient. The silicone rubber heaters are constructed with a wire-wound element or an etched foil element. The heater construction creates a very thin heater allowing it to fit applications where space is limited.
- Designed to the exact shape and size needed which conforms to the component and/or equipment
- More than 80 designs available immediately from stock reduces downtime
- Constructed with wire-wound or etched foil elements provides the desired flexibility for many dynamic applications and delivers low mass and easily repeatable distributed watt densities
- Moisture and chemical-resistant silicone rubber material provides longer heater life
- Vulcanizing adhesives or fasteners allows heaters to be easily bonded to parts

MILLED GROOVE TUBULAR HEATERS
PRECISION FORMED TO YOUR HOT RUNNER MOLD APPLICATIONS
WATROD milled groove heaters are precision-formed and customized to your hot runner mold application. Even tight radius bends of 0.250 inch maintaining tolerances of ±0.062 to ±0.002 inch are possible. This capability not only allows you freedom to design for the optimum uniform heating pattern for your plastics process, but also guarantees quick and easy installation.
Simply send your groove dimensions in a detailed drawing or on CAD file. Depending on the formation requirements, the resulting CAD design will be transferred to either Watlow’s CNC bending equipment or a highly skilled bending operator.
A variety of sheath materials are available including alloy 800, 304 stainless steel and 316 stainless steel, each offering unique advantages of long life in high temperature molds, rigidity to maintain shape during shipment and corrosion resistance.
Watlow not only delivers the heat fast to the process with efficient heat transfer, but guarantees the heater’s fast delivery, too. While Watlow guarantees standard delivery within three to four weeks, tough delivery schedules are Watlow’s specialty.
- Precise conformity to customer specifications ensures easy installation
- Alloy 800 sheath material are corrosion resistant and capable in high-temperature environments
- 304 stainless steel features excellent pliability – best choice for small bend radii
- Superior resistance coil design produces even heating
- Threaded stud or lead wire termination as required provides robust options for challenging environments

MINERAL INSULATED NOZZLE HEATERS
FEATURING WATLOW’S EXCLUSIVE MINERAL INSULATION (MI) TECHNOLOGY
The MI nozzle heater from Watlow is a high-performance heater. The nozzle heater’s performance and name are derived from Watlow’s exclusive mineral insulation—a material with a much higher thermal conductivity than mica and hard ceramic insulators used in conventional heaters.
A thin layer of the “high” thermal conductive MI material is used to electrically insulate the element wire from the inside diameter of the heater sheath. A thicker, “low” thermal conductivity layer backs up the element wire, directing the heat inward toward the heated part. The result is more efficient heat transfer—a performance solution lowering element wire temperatures and increasing heater life.

MINERAL INSULATED STRIP HEATERS
THIN, RESPONSIVE HEATER SETS STANDARDS FOR PERFORMANCE AND DURABILITY
The MI strip heater is a thin, responsive heater that uses the most advanced heater construction techniques. A nickel-chromium element wire is embedded in Watlow’s exclusive mineral insulation material, which has a much higher thermal conductivity than the mica and hard ceramic insulators used in conventional heaters. This thin layer of insulation brings the element wire closer to the heater sheath. The result is heat flows easily from the element wire to the sheath allowing the wire to run cooler than conventional heaters and increasing heater life.

MINERAL INSULATED THERMOCOUPLES – STYLE AC – MINI PLUG OR JACK TERMINATION
WATLOW’S MINERAL INSULATED (MI) THERMOCOUPLES ARE FAST-RESPONDING, DURABLE AND CAPABLE OF HANDLING HIGH TEMPERATURES.
Manufactured with best-in-class XACTPAK®, Watlow’s trademark for metal sheathed, mineral insulated (MI) thermocouple material, XACTPAK responds fast because the protective metal outer sheath allows use of smaller diameter thermocouple conductors. The rock hard compacted MgO insulation further enhances the sensor’s ability to “read” temperature by transferring heat quickly to the measuring junction.
The XACTPAK protecting sheath and compacted insulation outperform bare wire thermocouples in most applications
