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

375 FINNED STRIP HEATERS
EFFICIENTLY CONDUCTS HEAT FROM NICKEL-CHROME ELEMENT WIRE TO THE SHEATH
Watlow’s 375 finned strip heaters are constructed of highly-compacted MgO-based insulation, which conducts heat efficiently from the nickel chromium element wire to the sheath. Two-inch wide (51 mm) aluminized steel fins are attached in a way that maximizes surface contact so heat is transferred into the air faster. Lower sheath temperature and element life are all maximized by this finned construction.
Finned strip heaters com in available lengths from 5 1⁄2 to 48 in. (140 to 1220 mm).
- Nickel chromium element wire is centered for heat uniformity
- Aluminized steel sheath operates at higher temperatures and reduces corrosion
- Optional 430 SS sheath provides a solution for extreme corrosive environments

375 HIGH-TEMPERATURE STRIP HEATERS
RUGGED HEATER CAPABLE OF HIGH TEMPERATURES AND HIGH WATT DENSITIES
Named for its 0.375 in. (9.5 mm) thickness, the rugged Watlow 375 strip heater is capable of both high temperatures and high watt densities.
Watlow begins construction by accurately placing a coiled, nickel-chromium element wire in the center of the heater. The element wire is then embedded in magnesium oxide (MgO)-based insulation compacted into a solid mass creating excellent heat conductivity and high dielectric strength. The heater is then enclosed in aluminized steel or 430 stainless steel sheathing.
- Nickel-chromium element wire is centered in the heater assures uniform heat
- Aluminized steel sheath operates at higher temperatures and resists corrosion
- Optional 430 stainless steel sheath meets temperature requirements that reach up to 1200°F (650°C)

E-SAFE
POWER SWITCHING AT HIGH AMPERAGE AND HIGH AMBIENT TEMPERATURES
The E-SAFE® II hybrid power switch provides reliable and accurate power switching up to 35 amperes at 158°F (70°C). This mercury-free product is specifically designed to operate in the higher ambient temperatures of foodservice applications.
The use of mercury in relays is being eliminated by regulations in the United States and around the world. The E-SAFE II is the best choice for replacing mercury relay switches and the best performing product at the most economical price. Because of the product’s unique design, there is no need to purchase costly heat sinks used with traditional solid state relays (SSRs). In addition, since this is a three-phase device, there is no need to wire multiple command signals. With a switching life of millions of cycles and an ambient rating of 158°F (70°C), with no heat sink required, this product is superior to typical SSRs.
The E-SAFE II hybrid power switch provides foodservice operators with longer contact life and higher performance than typical mechanical contactors used in equipment. By using Watlow’s patent NO-ARC technology, the E-SAFE II can switch millions of cycles to increase the life of the product with reduced noise and increased temperature accuracy. E-SAFE II’s inherent ability to operate at fast cycle times make it an ideal complimentary product for a time, proportional, integral derivative (PID)controller.
E-SAFE II is mercury free, RoHS compliant by design, CE approved and C-UL®/UL® recognized. The reliability of the product is protected by a two-year warranty.
