Tubular Heaters

Tubular heaters are very versatile in terms of heating applications. They are a popular choice for air heating applications and can also be used for immersion heating. They are available in a variety of sheath materials, such as copper, INCOLOY, steel, or stainless steel (type 304). The sheath material also plays a vital role in corrosion and temperature resistance. Standard tubular heater sheath materials include steel, copper, and stainless steel (type 304), but they are also available in INCONEL and titanium. You need to consider the sheath material when choosing a tubular heater, as different sheath materials have different watt densities.

Standard tubular heaters

Standard tubular heaters are ideal for use in various applications that require a large amount of heat. They come in a variety of sizes and watt densities. Their flexibility and durability make them an excellent choice for many industrial, scientific, and commercial applications. These tubular heaters are available with a variety of terminations, including quick disconnect spades, screw lugs, and ceramic-to-metal hermetic terminal assemblies.

The most common method of mounting tubular heaters is through brazing, soldering, or welding. Mounting collars and brackets are widely used in non-pressurized or sealed containers. Bulkhead fittings are another option for mounting tubular heaters. The type of connection used will depend on the pressure, type, and quality of gas or liquid that is to be heated.

Standard tubular heaters come in single and double-ended versions. They can be clamped to objects or fitted into milled groove platens. They can also be mounted in ducts. The Single-Pass Tubular Heater is available in single-ended and double-ended versions. They contain a helical Nichrome resistive wire centered in a sheath filled with MgO. The MgO helps stabilize the coil.

Multicoil heaters

Multicoil tubular heaters combine multiple coils and thermocouples to provide a highly accurate temperature measurement. They are available in various configurations and can be easily mounted. They also come with standard materials including 304 and 316 stainless steel. Contact Watlow for pricing and other information.

These tubular heaters are designed to heat liquids and contact surfaces. They come with several construction features and are UL and CSA recognized. They are available in single and double-ended designs. They can also be custom bended to meet the requirements of the application. Watlow MULTICELL tubular heaters have a maximum sheath temperature of 1800degF.

These tubular heaters are available in various sizes, including 0.260-inch and 0.625-inch models. Their sheaths are made from stainless steel or copper. The heat they generate is efficient and long-lasting. There tubular heaters are many common applications for multicoil tubular heaters.

Electric firebar heaters

Electric firebar heaters can be purchased as single-ended or double-ended units. The difference between the two types is in the insulation. The former is composed of magnesium oxide insulation, while the latter uses nichrome resistance wire. The latter has a lower operating sheath temperature.

They can be used for a range of applications and can operate from 120 to 480 V. These units are suitable for applications that require high heat transfer, as they are built with superior materials. Depending on the application, the heating element material is custom-tailored for maximum efficiency. When choosing a tubular electric firebar heater, be sure to consider the application requirements.
