The Industry's Most Complete Line of Electric Heaters

Watlow has developed a line of process air heaters that offer performance and versatility in medium to low temperature applications. This rugged and reliable line of industrial heaters efficiently conducts heat.

Air heaters can be used to prevent freezing and condensation in electrical and mechanical housing or can be placed in ducts for forced air heating.

Flexible heaters from Watlow are thin, bendable and shaped to fit almost any type of equipment.

Fluid delivery heaters produce consistent results by reducing temperature and viscosity variations.

Bolted or clamped to flat surfaces, these heaters can provide freeze or moisture protection.

Watlow’s cartridge heaters and insertion heaters can be inserted into holes, used as immersion heaters placed directly in liquid or in protective wells, or can be mounted in pipes or vessels.

Watlow's immersion heaters are designed primarily for direct immersion in liquids

Watlow's immersion heaters are designed primarily for direct immersion in liquids such as water, oils, solvents and process solutions.

High-temperature heaters offer capabilities such as ultra-fast ramp rates, precise temperature uniformity and high temperatures for applications requiring low thermal mass.

High-temperature heaters offer ultra-fast ramp rates, precise temperature uniformity and high temperatures for applications requiring low thermal mass.

These heaters are formed to fit cylindrical parts. Applications for these heaters range from industrial processes to medical applications.

These heaters can be clamped to most any cylindrical surfaces and used at temperatures up to 1400°F (760°C).

Single- and double-ended tubular heaters lend themselves to virtually the entire range of immersion and air heating applications.

These compact heating systems are ideal for fluid and gas applications such as purified and inert gases, supercritical fluids and liquids like de-ionized water.

Specialty heaters are designed for thermal applications where high performance is required, and fast response and uniformity are essential.

Used in non-contact applications where conduction or convection heating is not practical.
