WATTCO™ tubular elements are the most versatile and best suited solutions to a large number of applications. This is why they are found in major modern heating applications and are known for their superior qualities. Tubular elements can be:

• Clamped• Immersed• Cast into metal• Easily removable

Surface tubular elements are used for surface heating and are sold separately or made into process heating assemblies including:

• Flange heaters• Screwplug heaters• Circulation heaters, vessels• Strip elements• Over-the-side heaters• Cartridge heaters• Duct heaters• Band heaters• Infrared heaters

WATTCO™ TUBULAR HEATER

Depending on their rating, sheath and shape, WATTCO™ tubular elements are used in a variety of heat applications (conduction, convection, radiation heating) that require process temperatures of up to 750°C (1 382°F) to heat liquids, gases and solids.

• Easy to install• Configurable to virtually any shape• Compact• Precise and easy control of heat output• Durable • Easy to maintain

KEY FEATURES

• Standard diameters: 0.260”, 0.315”, 0.375”, 0.430”, 0.475” and 0.625”• Available in a broad variety of sheaths, diameters and ratings• Supplied with electrically isolated sheath• Provide superior internal electrical insulation and heat

conduction

Please consider the following factors to select the ideal WATTCO™ tubular heater for your application:

• Heating element watt density• Sheath material (corrosive or non corrosive) o Temperature of the corrodent o Degree of aeration of the corrodent o Velocity of the corrodent o Ambient temperature

THREADED FITTING (FIG. 1)

• Brazed, crimped or welded to the element’s cold section.• Used as a tight joint to the heater, which is fixed in open tanks or vessels. • Supplied in brass, steel, or stainless steel.

COMPRESSION FITTING (FIG. 2)

• Available in nickel-plated brass for field installation on elements of 0.375”, 0.430”, 0.475” elements diameter.

TERMINAL BOX (FIG. 3)

Moisture resistant terminal boxes are: • Factory installed

Note: • Special requests can be made to have holes predrilled into the terminal boxes. This can provide easier tubular installation on site. • Elements can require fittings to connect to the terminal box.

ELEMENT CLAMP (FIG. 4)

• The two-piece stainless steel clamps shown to the right can serve as element standoffs in ovens or tanks. • Use half of the clamp with a stud welded to the tank or plate to suit clamp-on applications.• Available "C" dimensions: 1 1/4", 1 7/16", 1 5/8" and 1 15/16".

MOUNTING BRACKETS (FIGS. 5-7)

• WATTCO™ can crimp standard mounting brackets to elements to help with installation. • Special brackets can be configured on to your elements.

• Select the proper element by first specifying if the element has a minimum diameter of 0.430" if the power supply voltage is more than 300V.

Depending on your requirements, special terminals can be installed on the 0.315" diameter elements so they can be used up to 600V.

• Standard fin sizes and pitches supplied by WATTCO™ are listed in Table 1 above. Other sizes are available on special order.

Watt Density = Sheath watt density X Element surface area per lineal inch.

• Determine the number of heated length of element required for a specific wattage output. You will need more than one element for larger wattage or three-phase installations.

EXTRA FEATURES: Refer to pages 1.5 and 1.8WHEN ORDERING, PLEASE SPECIFY: Quantity, catalogue no., voltage, wattage, and extra features required.

WATT DENSITY

Typical WATTCO™ finned heaters have up to 30 watts/in of total heated surface area. If you require higher heat output, please consult with our sales department.

FACTORS TO CONSIDER WHEN SELECTING A SAFE WATTAGE RATING

• Air velocity over heater• Outlet air temperature • Allowable sheath temperatures

See Figure 2 on page 1.10 to find out about the required air velocity to prevent overheating.

MOUNTING

The following heaters can be fixed with brazed, crimped, or welded plates (refer to Figures 5 to 7 on page 1.8). Refer to page 1.5 to find out about standard elements with factory-fixed fittings for installa-tion.

WATTCO™ heaters are available in lower wattage ratings (i.e., an air velocity of 800 ft./min. and an outlet air temperature of 500°F).

In Figure 2 on page 1.10, it can be seen that 6 watts/in would be the maximum recommended watt density. As standard heaters are 10 watts/in , special elements with 6/10 or 60% of the kW ratings are required (refer to Tables 1 or 2).
