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

ECO-HEAT® SYSTEM
WATLOW’S ECO-HEAT SYSTEM FOR DIESEL GENERATORS UP TO 9L
Low exhaust gas temperatures (resulting from low load or low ambient conditions) can compromise the performance of your diesel generator’s aftertreatment system and eventually lead to unplanned downtime and expensive repairs. Whether your aftertreatment configuration has a DPF, an SCR or just a DOC, Watlow’s ECO-HEAT system delivers reliable electric heat that can quickly raise the exhaust gas temperature to the correct level.
Designed to be installed in the exhaust pipe, the ECO-HEAT system places heat directly where it is needed. It uses electricity from your diesel generator to operate when exhaust gas temperatures are too low. Unlike an external load bank that requires additional space and wastes heat to the surrounding environment, the ECO-HEAT system is compact and efficient. You can think of it as a smart internal load bank for your diesel generator. When you place a higher load demand on your generator, the ECO-HEAT system will shut off as the engine exhaust temperature reaches an acceptable threshold.
- Reduce fuel consumption by over 50 percent as compared to an external load bank
- Enables passive diesel particulate filter (DPF) to regenerate more effectively
- Avoid unplanned downtime and expensive service calls
- Eliminate the need for an external load bank
- Place exhaust heat exactly where it is needed

CERAMIC FIBER HEATERS
THE BETTER FURNACE TECHNOLOGY HEATER
Ceramic fiber heaters offer some of the highest temperature heating element capabilities in the Watlow family of heaters. Heating units constructed of ceramic fiber insulation isolate the heating chamber from the outside. Ceramic fiber heaters are extremely low mass, high insulation value units with self-supported heating elements. Many applications can benefit from the convenience of the heating element and insulation combined into one package. Its lightweight, low-density properties make it ideally suited for high temperature applications requiring low thermal mass.
- High temperature ICA resistance elements bounds integrally into required position
- Lightweight, low-density alumina-silica composition molded into shape ensures a firm, thermal shock resistant, self-supporting unit at all operating temperatures
- Operating temperatures up to 2200°F (1204°C) provides high-temperature performance not possible with many other heater types
- Low mass ceramic fiber insulation allows the heater to reach process temperature quickly, efficiently heating the load instead of itself
- Works directly off common power line voltages eliminating the need for expensive transformers or complex power control systems

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)
NICKEL-CHROMIUM RESISTANCE WIRE
Assures even and efficient distribution of heat to the sheath because the wire is precisely wound and centered in the heaterCONDUCTOR PINS

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
Transfers heat more efficientlyHIGH EMISSIVITY SHEATH
Provides better heat transfer and longer 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 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.
