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

MULTICOIL™ HEATERS
MULTIPLE COILS AND THERMOCOUPLES PACKAGED IN ONE SHEATH FOR QUICK INSTALLATION
The MULTICOIL heater tubular element with multiple coils and/or thermocouples inside one sheath answers the need for a versatile, innovative tubular multiple coil heater. Watlow’s patented method of packaging a thermocouple inside of a heater with one or more resistance coils gives the ability to sense a heater’s internal temperature accurately, every time.
Moreover, this is the first tubular heater in the industry with three-phase capability. The three coil, three-phase heater will offer a compact package solution while delivering the full power required in a compact heater package. Previously three separate heaters would have been required to do the same job; therefore Watlow’s MULTICOIL heater capabilities save money.
- Three-phase capability results in one element versus three, lower amperage, reduced installation time and lower overall cost
- Multiple coil operations reduces inventory by allowing dual voltage capability
- Versatile forming capabilities forms into many configurations
- Internal thermocouple construction eliminates contamination buildup around the external sensing tip, reducing the possibility of false readings

MULTIPOINT THERMOCOUPLES – STYLE AW
ACCURATELY MEASURES TEMPERATURES AT VARIOUS LOCATIONS
Temperature variances exist in all systems, regardless of materials, working fluid or system design. There is not a process that involves heating a particular medium where temperature of that medium is consistent throughout— temperature gradients always exist. Sensing temperature at a single location during a process is acceptable for many applications because temperature gradients are often insignificant. However, there is a need for many applications to monitor temperature in multiple locations to ensure a safe, accurate and cost efficient process. Installing multiple, independent temperature sensors may be impractical due to cost or space limitations.
Multipoint temperature sensors accurately measure temperatures at various locations along the sensor’s length. They are used across a broad range of processes and installations—predominately in applications involving a large or complex process where close temperature control is necessary.
Multipoint temperature sensors are designed to meet requirements of specific applications that include temperature, pressure, chemical environments, time response and number of points required. Sensors are constructed from a variety of protecting tube materials that use XACTPAK mineral insulated, metal-sheathed cable. Multipoint temperature sensors are available in standard or special ASTM thermocouple calibration tolerances. For applications requiring extreme accuracy, special constructions can be made with platinum resistance temperature detectors (RTDs).
