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 designed and manufactured the first swaged cartridge heater and revolutionized the heating element industry.
With premium materials and tight manufacturing controls, Watlow's cartridge heaters (insertion heaters) provide superior heat transfer, uniform temperatures, resistance to oxidation and corrosion and long life even at high temperatures.
Tubular heaters are used for immersion and air heating applications. They can be clamped to objects such as vessels and tanks, fitted into milled groove platens, immersed directly into a liquid being heated or even mounted in ducts for heating air and gas. Heaters are available as single- and double-ended, and can be formed to complex geometries. Single- and double-ended tubular heaters lend themselves to virtually the entire range of immersion and air heating applications. They have a variety of mounting and termination options that make them ideal for industrial applications. Watlow® tubular heaters are UL® and CSA component recognized up to 240V.
Flexible heaters are commonly used to heat irregular surfaces, shapes and pipes. These heaters can be bonded or fastened to parts and are often used for freeze protection. Flexible heaters from Watlow are thin, bendable and shaped to fit almost any equipment. Heat can be applied to the most complex shapes, geometries, curves and pipes conceivable without sacrificing efficiency or dependability.
These heaters can be immersed directly in the liquid being heated or put in protective wells. Multiple style mounting adaptors are available. Watlow's immersion heaters 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. These versatile heaters can also be formed and shaped into various geometries for radiant heating and contact surface heating applications. UL® and CSA component recognized elements are available.
Watlow’s diverse array of circulation heaters range from quartz heaters for aggressive chemicals to large pressure vessel heaters with capabilities up to 3000psi. These heaters can be used for liquids or gases in various applications. Watlow's circulation heaters are compact heating systems for fluids and gases. These heaters are ideal for applications such as purified and inert gases, supercritical fluids and liquids like de-ionized water for use in semiconductor and electronics industries as well as for general liquid and gas heating applications.
Watlow fluid delivery heaters provide overall reliable, responsive heating for fluid delivery systems in medical, analytical, water purification and general process applications. Watlow fluid delivery heaters offer precise, repeatable heating, control improving product life. Watlow® innovative fluid delivery heaters produce consistent results by reducing temperature and viscosity variations.
Watlow's syringe heater was developed for the needs of medical injection applications. The special design provides a heated fluid and drug delivery system solution with long operational life which improves system reliability while reducing equipment down time. Watlow's FREEFLEX™ heater unique design places the heating element and sensor directly in contact with the perimeter of the tubing to produce efficient temperature control of the tube contents. The FREEFLEX heater eliminates the need for heated reservoir systems in many applications.
Watlow’s 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. 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.
These high-temperature heaters are used for extreme high temperature applications. The heaters fit applications such as the construction of furnaces and chambers. Watlow leads the industry in developing high-temperature heating technologies and products in various sizes and constructions to fit a broad range of processes and applications. Watlow's MULTICELL™, FIREROD®, tubular and ceramic fiber heaters offer capabilities such as ultra-fast ramp rates, precise temperature uniformity and high temperatures for applications requiring low thermal mass. Heaters are sized and designed to accommodate small to large applications and various environmental conditions.
These specialty heaters are commonly used for high temperature applications or in cases where high watt densities are required. These versatile heating elements can be formed or machined to fit precise heating applications. Watlow specialty heaters are designed for thermal applications where high performance is required, and fast response and uniformity are essential.
Specialty heaters from Watlow have design flexibility to meet different applications requiring different construction methods. This flexibility allows the heaters to be configured in a variety of shapes and sizes depending on the application.
Bolted or clamped to flat surfaces these heaters can provide freeze or moisture protection. These heaters can be attached to tank or vessel walls for warming. Watlow's strip/clamp-on heaters are a 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. These heaters make use of the most advanced heat construction techniques.
These heaters can be clamped to most any cylindrical surfaces. The materials used in the construction of these heaters allows them to be used at temperatures up to 1400°F (760°C) or used at low temperatures for freeze protection. Watlow's line of band/barrel heaters are available for fast delivery and can be easily installed into original equipment manufacturer (OEM) and end user applications. This variety of heaters allows the user to specify the construction needed to result in the best heat solution.
