| Watlow® FIREROD® cartridge heaters revolutionized the
heating element industry in 1954 when it was patented as
the first swaged cartridge heater. With premium materials
and tight manufacturing controls, the FIREROD heater
continues to provide superior heat transfer |
|
|
|
|
|
| Available in single- or double-ended termination styles,
the versatile and economical WATROD tubular heating
element from Watlow® lends itself to virtually the entire
range of immersion and air heating applications.
The single-ended WATROD tubular design has both
terminals at one end. |
|
|
|
|
|
| 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 stock and made-to-order sizes,
Watlow screw plug immersion heaters feature both
WATROD round and FIREBAR® flat tubular elements. |

| The miniature heated polymeric tubing assemblies from
Watlow® provide a flexible heat-up and transport system
for moving fluids in tubing as small as 1⁄32 in. (0.8 mm)
inside diameter. FREEFLEX® heats fluids up to 212°F
(100°C) and maintains temperature during transfer from
a reservoir to a point of use. |

|
|
|
| Constructed of sturdy 0.430 in. (11 mm) diameter
WATROD heating elements mounted to a 1⁄4 in. (6 mm)
thick steel flange, duct heaters are easily adapted to
many non-pressurized air-heating systems.
They are easily installed in applications requiring a wide
range of temperature versus air flow combinations. |
|
|
|
|
|
| Flexible heaters from Watlow® are just what the name
implies: thin, bendable and shaped to fit your equipment.
You can use your imagination to apply heat to the most
complex shapes and geometries, without sacrificing
efficiency or dependability. With Watlow’s customization
capabilities, |

|
|
| The heated part concept from Watlow® can help simplify
many complex heating problems.
The heated part is much more than a heater, it is a
functional component of equipment that can be designed
in the exact shape and size needed. |
|
|
|
|
|
| The ULTRAMIC® heaters from Watlow® are designed for
thermal applications where the high performance
of an advanced ceramic heater is required to ensure
optimal effectiveness of the equipment and process. |

| The Mineral Insulated (MI) strip is a thin, responsive
heater setting unmatched standards for performance
and durability. It makes use of the most advanced
heater construction techniques, including embedding a
nickel-chromium element wire in an exclusive mineral
insulation from Watlow®. |
|
|
|
|
|
| The versatile Watlow® cable and coil heater can be
formed to a variety of shapes as dictated by its many
applications. Cable heaters are small diameter,
high-performance units, fully annealed and readily
bent to a multitude of configurations. |
|
|
|
|
|
| The Mineral Insulated (MI) nozzle heater from Watlow®
is a high-performance heater. Its performance and name
are derived from Watlow’s exclusive mineral insulation—
a material that has much higher thermal conductivity
than the mica and hard ceramic insulators used in
conventional heaters. |
|
|
|
|
|
| The diverse RAYMAX® heater line from Watlow® allows
you to solve virtually any application requiring radiant heat.
Watlow’s capabilities cover a wide range of needs, from
contamination-resistant surfaces, to fast responding
high-temperature panels, to replaceable tubular elements. |

| Many applications requiring a fixed temperature set
point have relied on mechanical thermostat devices
(thermostats) for thermal control. But, thermostats are
inadequate for many applications because of the
long-term reliability issues such as 100,000 cycle rating
and poor temperature control. |
