Advanced Ceramic Heaters
Watlow's ULTRAMIC™ 600 heaters 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.

Band Heaters
Led by the high performance MI (mineral insulated) Band heater, the patented, flexible THINBAND® heater and the standard mica band heater for specialized constructions, Watlow's band and nozzle heaters are ideal for every type of plastics processing equipment.

Cable Heaters
The versatile Watlow cable heater can be formed into a variety of shapes as dictated by its many applications. These small diameter, high performance units are fully annealed and readily bent to your desired configuration.

Cartridge Heaters
The Watlow FIREROD heater enters its 50th year of industry leading expertise as the premier choice in swaged cartridge heating. With premium materials and tight manufacturing controls, the FIREROD heater continues to provide superior heat transfer.

Cast-in Heaters
When Watlow creates a custom-engineered cast-in product, the result is more than just a heater. It's a "heated part" that becomes a functional component of your equipment, designed in the exact shape and size you need.

Ceramic Fiber Heaters
Ceramic fiber heaters intergrate a high temperature iron-chrome-aluminum (ICA) heating element wire with ceramic fiber insulation. Numerous stock, standard and/or custom shapes can be provided, achieving the "heated insulation" concept for your high temperature, non-contact applications.

Flexible Heaters
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 geometries conceivable without sacrificing efficiency or dependability.

Multicell Heaters
The multicell heater from Watlow offers independent zone control for precise temperature uniformity, loose fit design for easy insertion in and removal from the equipment and extreme process temperature capability. The heaters are available with up to eight independently controllable zones and one to three internal thermowells.

Radiant Heaters
With Watlow's diverse RAYMAX radiant heater line, we have a solution for almost any application requiring radiant heat. Our capabilities cover a wide range of needs, from contamination-resistant panel heaters to fast-responding quartz tubes to rugged tubular elements and high temperature ceramic panels.

Strip Heaters
Watlow's mica and 375 strip heaters are the versatile solution for a number of applications. They can be bolted or clamped to a solid surface for freeze and moisture protection, food warming and other applications. The 375 finned strip heaters are commonly used for air heating, drying ovens and space heaters.

Thick Film Heaters
Watlow layers thick film resistor and dielectric materials on quartz, stainless steel and ceramic substrates to produce high performance industrial heaters. The thick film heaters provide very fast temperature response and uniformity on a low-profile heater. Thick film heaters are ideal for applications where space is limited.

Tubular Heaters
Watlow's WATROD tubular heater elements and flat FIREBAR elements are designed primarily for direct immersion in liquids such as water, oils, solvents and process solutions, molten materials as well as air and gases. By generating all the heat within the liquid or process, these heaters are virtually 100 percent energy efficient.
