FIREROD® IMMERSION HEATERS
COMPACT HEATER ENABLES VERSATILE HEATING SYSTEM DESIGN
FIREROD water immersion heaters are ideal for replacing large screw-plug immersion heaters. Because of its compact size the product can be very versatile when designed into a heating system.
These water immersion heaters come complete with a brass 3⁄4 inch National Pipe Thread (NPT) double threaded fitting, which allows you to add conduit boxes. Also, FIREROD immersion heaters are sealed at the lead end with a silicone rubber seal.
Solid copper leads, with silicone rubber sleeves, are provided for unrestricted wiring. These units are recommended for immersion in water or 90+ percent water soluble solutions.
- Nickel-chromium resistance wire precisely centered in the unit ensures even, efficient distribution of heat to the sheath
- MgO insulation compacted to the proper density results in high dielectric strength and contributes to faster heat-up
- Alloy 800 sheath resists corrosion from water
- Metallurgically-bonded conductor pins for trouble-free electrical continuity
- 240 and 480VAC voltage allows flexibility in wiring the heater for use in your particular applications

MINERAL INSULATED THERMOCOUPLES – STYLE AC – STANDARD 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

LDH SERIES AND D SERIES DUCT HEATERS
EASILY ADAPTED TO MANY NON-PRESSURIZED AIR HEATING SYSTEMS
Watlow duct heaters are constructed of sturdy 0.430 in. (11 mm) diameter WATROD heating elements mounted to a 1⁄4 in. (6 mm) thick steel flange. These air duct heaters are easily adapted to many non-pressurized air-heating systems.
Duct heaters are easily installed in applications requiring a wide range of temperature versus air flow combinations.
The modular duct heater offers increased reliability. The individual modules are removable through the housing of the assembly, which eliminates the need to pull the complete heater from the ductwork. This reduces downtime costs because the heating elements can be replaced individually. Performance improvements include quicker response time and reduced infiltration from the air stream being heated into the electrical enclosure.
Watlow air duct heaters offer advantages over gas or oil fired and open coil electric units with:
-Installation flexibility—no flues or fuel lines
-100 percent energy efficient—no energy loss up the flue
-Universal availability of electricity
-Resistance coil in sheath is protected from corrosive environments
-Duct heaters with general purpose enclosures meet UL® and CSA component recognition to 480 and 600VAC maximum respectively—UL® and CSA file numbers are E52951 and 31388.- Long life alloy 800 sheath resists corrosion/oxidation while protecting resistance coils against contamination
- MgO insulation filled elements compacted to rock hard density maximizes dielectric strength, heat transfer and life
- Field replaceable heating elements permits easy service and reduces downtime
- General purpose terminal enclosure offers easy access to wiring
- WATROD hairpins are recompacted after bending to eliminate hot spots and electrical insulation voids

HIGH-TEMPERATURE FIREROD® CARTRIDGE HEATERS
SWAGED CARTRIDGE HEATER IDEAL FOR HIGH-TEMPERATURE APPLICATIONS
The Watlow HT FIREROD cartridge heater is especially designed for high-temperature platen applications up to 1600°F (871°C). The HT FIREROD high temperature cartridge heater utilizes the same industry leading design principles used on all of Watlow’s FIREROD products. Taking the cartridge heater one step further enables the HT FIREROD to withstand application temperatures up to 400°F (204°C) higher than standard cartridge heaters.
There are certain differences in the HT FIREROD design which are important in high temperature applications:
-HT FIREROD cartridge heaters are specially constructed with an end seal that is virtually airtight to reduce the effects of resistance wire oxidation
-The high-temperature sheath is treated to improve its emissivity for better heat transfer- High-temperature seal results in longer heater life
- Alloy 800 sheath transfers heat more efficiently
- High emissivity sheath provides better heat transfer and longer heater life
HIGH-TEMPERATURE SEAL
Reduces exposure to the atmosphere which minimizes oxidation of the winding wires resulting in longer life of the element; note: first 2 in. (51 mm) must be outside the platen in free airALLOY 800 SHEATH

HIGH-TEMPERATURE TUBULAR HEATERS
IDEAL FOR PROCESS AIR HEATING APPLICATIONS REQUIRING HIGH TEMPERATURES
Watlow manufactures high-temperature tubular heaters to bridge the gap between standard tubular heaters and Watlow MULTICELL™ heaters. This high temperature heater is well suited for process air heating applications in excess of 1300˚F (704˚C), resulting in a maximum sheath temperature of 1800˚F (983˚C). Controlled lab testing between the new design and current tubular designs shows an increase in life of approximately 50 percent.
The high-temperature heaters consist of an engineered tubing with an outer sheath of Alloy 600 and a special internal construction. The outer sheath offers high temperature capabilities, reduced oxidation as well as corrosion resistance.
The tubular heater offering is available in 0.430 and 0.375 inch diameters that are configurable either as formed tubulars or process heaters. The tubular heaters can also be welded to flanges and plates for mounting purposes. Maximum sheath length available is 275 inches for the 0.430 inch and 0.375 inch diameters. The factory should be contacted for longer sheath lengths.
- Alloy 600 sheath material and a special internal construction maximizes performance and corrosion protection in tough applications
- Dual-ended termination Installs into flanges and screw plugs similarly to standard product configurations
- Bendable in standard formations makes the heater easy to apply in a wide variety of applications

METRIC FIREROD METRIC CARTRIDGE HEATERS
CARTRIDGE HEATER BUILT TO MEET THE SPECIFICATIONS OF THE GLOBAL MARKET
The Watlow FIREROD not only sets the industry standard for cartridge heaters, but continues to make improvements in construction and design. Among those improvements is the FIREROD metric cartridge heater, a variation of the FIREROD cartridge heater built to meet the exact specifications of the global market.
Like its counterpart, the metric FIREROD consistently outperforms other cartridge heaters with its design solutions such as its exclusive resistance wire winding and swaging process. These processes bring the resistance wire closer to the sheath and compacts the MgO insulation to maximize heat transfer. The end result is longer service life and better efficiency.
- Nickel chromium resistance wire ensures even, efficient distribution of heat to sheath
- Magnesium oxide insulation of specific grain and purity results in high dielectric strength and faster heat-up
- Alloy 800 sheath resists oxidation and corrosion from many chemicals, heat and atmospheres
- Minimal spacing between element wire and sheath results in lower internal temperatures and accommodates design with fewer or smaller heaters
- UL® and CSA approved flexible stranded wires with lead insulation rated to temperatures of 250°C (480°F)
