Components Overview

COMPONENT HEATERS

Component Heaters include the basic types of heating elements:

• Tubular Elements • Thin Blade Heaters • Strip Heaters • Ring & Disc Heaters • Band & Nozzle Heaters

• Cartridge Heaters • Flexible Heaters • Specialty Heaters

Component heaters may be used by themselves to solve many heating prob- lems. They may also be incorporated into more complex heating systems, providing a complete thermal solution for your heating requirements. Chromalox carries the widest selection of standard component heaters in many shapes, sizes and wattages. Chromalox is the “First Choice for Thermal Solutions”. Applications With component heaters, most often the shape and size will be the determining factor in most heater applications. Brief descriptions of each heater type follow, with selection guidelines that lead to a detailed description on individual product pages.

Thin blade heater elements provide more surface area than standard tubular elements to offer greater wattage or lower watt densities. Select from many sheath materials with watt densities to 75 W/in 2 and sheath temperatures as high as 1200°F. Heating elements can be as long as 120" and are capable of being formed into many configurations for heating via im- mersion, direct surface contact or convection. Three wire construction within the element provides uniform heating. Available in single or 3-phase current terminations with a 120 to 240 volt range.

Tubular heating elements perform excep- tional heat transfer by conduction, convection or radiation to heat liquids, air, gases and surfaces. In most heater assemblies, tubular element design configurations vary — round, triangular, flat press and formed. Bends are made to customer requirements Custom built from 0.200" to 0.625" diameters, a multitude of sheath materials with sheath temperature capabilities up to 1600°F, watt densities to fit many applications and up to 690 volts. Avail- able with over 20 optional terminations and many stocked accessories.

Tubular Heaters Application Guidelines

Construction Chromalox tubular elements are used for prac- tically the entire range of electric resistance heating applications. A metal sheath material is selected. The proper size resistance wire for the heating element is carefully selected and verified by computer calculations to ensure the longest service life possible. The high quality resistor wire is carefully tested and inspected to meet rigid specifications prior to being coiled. The resistance wire is then welded to a terminal pin to assure positive connection. The wire is centered in a metal sheath and insulated with high quality magnesium oxide which is highly compacted around it and acts as an electri- cal insulator. This material readily conducts the heat from the coiled resistor to the metal sheath and puts the heat where it is required, which results in maximum heater life. The highly compacted magnesium oxide holds the terminal pin securely allowing maximum torque of eight inch pounds when tightening terminal hardware

In Moving Air — Compression fittings, factory mounted fittings or brackets will mount a tubular element in a duct or air heating chamber.

• Up to 172" Lengths (Std.) • 75 - 10,000 Watts (Std.) • 120, 240 and 480 Volt (Std.) • 3 - 53 W/In 2 (Std.) • Max. Sheath Temp. • Copper — 350°F • Steel — 750°F • Stainless Steel — 1200°F • INCOLOY ® — 1600°F Applications Extremely Versatile Heat Source — Highly adaptable, the tubular element, in its many forms and as a component of Chromalox packaged heaters and systems, has vastly increased the scale of electric heating applica- tions. The heaters' mechanical and electrical flexibility are important to process engineers and product designers alike, as heating requirements can be matched accurately by proper selection from a great variety of element lengths, sheaths, diameters and watt densities. Product Uniformity — Electric tubular heating elements provide a method of applying the exact amount of heat required at a specific area. When used with appropriate temperature control, product repeatability is assured. Increased Production — Adding heat to a process often leads to increased production. For example, drying time may be reduced by heating the air or the product being dried. Chemical and cleaning processes are often more efficient when heated and a more consis- tent finished product results. Less Down Time — Chromalox quality tubular elements with properly applied watt density and sheath material will provide long life, less down time and little or no maintenance.

Components

Tubular Heaters Application Guidelines (cont’d.) Liquid Heating Direct Immersion — Water and water solu- tions can generally be heated to any desired temperature. If liquid is under pressure, temperatures should not exceed the maximum sheath temperature of the element minus 100°F. Note — Heated section of element must be immersed at all times when energized. Longer cold ends can be provided, if required. Threaded fittings are available for mounting through tank walls. Oil Heating Steel sheath elements can be used for heating oils, heat transfer oils and other solutions not Use watt densities compatible with work temperatures. Refer to Technical section of this catalog. Heaters mounted horizontally must be supported to avoid sagging at high temperatures. Proper spacing of supports may vary with application temperature, element diameter and sheath material. Generally 12 to 18" spacing of supports is adequate. Max. Sheath Temperatures To assure maximum life, tubular elements should not be operated beyond the tempera- tures in this tabulation: corrosive to steel sheath. Air & Gas Heating

TUBULAR

Where air flowing over elements permits use of higher watt densities, make sure air flow is evenly distributed. Allow approximately 1/8" per foot of element length for expansion and contraction of ele- ments (i.e., 24" long element could expand 1/4" when energized). Clamp-On Heating Use watt densities compatible with work temperatures. Refer to Application Guide for Tubular Heating of Solids, Liquids, Air & Gas or use curve G-175S in Technical section. Heaters should be clamped tightly for good heat transfer but should be allowed to expand as they heat up. Heaters clamped too tightly will bow away from the heated surface which results in poor heating efficiency and possible heater failure. It is generally best to tighten the middle clamp first to hold the element. Other clamps should be tightened enough to hold, but back off 1/2 turn to allow for expansion and contraction. Heaters should be spaced on approximately two inch centers minimum. Heaters are commonly installed by clamping into machined grooves for better heat transfer.

Note — Depth of groove should never exceed element diameter to assure positive clamping. Grooves should be machined to the following tolerences:

TubularHeaters Design & Installation Guidelines Design Considerations

Terminal Selection — Stocked tubulars are shipped with standard terminals, see Terminal Options in this section. Many other terminals and terminal end seals are available made to order. CAUTION — Protect terminals from possible contamination from surrounding atmospheres such as oil fumes, chemical vapors from other processes, moisture, weather, etc. MgO insula- tion is hygroscopic. Vacuums — Tubular heaters operate at higher temperatures in a vacuum because there is no air to take away the heat. Therefore, watt densities are recommended to be 20 to 30% lower. It is recommended terminals of the element be kept outside of the vacuum. Code Compliance — Chromalox manufac- tures the highest quality heaters and con- trols and, where applicable, in compliance with such codes as the Canadian Standards Association (CSA), Underwriters Laborato- ries Inc. (UL) and Verification of Devices for Europe Testing and Certification Institute (VDE) and CE. Installation Guidelines Wiring — Must be in accordance with The Na- tional Electrical Code (NEC). It is important to use the correct wire gauge to carry the amperage required. A wire not large enough can overheat, become brittle and break. The ambient tempera- ture must also be considered in choosing the correct type of wire and insulation. Make sure wiring to terminals is tight. Keep terminals away from heat, if possible. (For higher temperatures, contact your Local Chromalox Sales office.) Mounting Methods— Elements can be supplied with threaded fittings for mounting thru walls of tanks, ovens, etc. Compression threaded fit- tings are also available for easy field installation. Rings, clips, brackets and washers can also be attached to elements for mounting purposes.

Easy Bending — To put heat where it is needed, tubular elements can be bent to fit most require- ments. See following pages for customer bend- ing and factory bending details. Bending should be done around a smooth round object such as a piece of pipe. For minimum bending radii, see Bending Guidelines. Triangular Cross-Section These unique cross-sectioned elements are specially designed for high element surface temperature applications, and wherever extreme rigidity is required. Triangulation — A patented extra step by Chromalox to increase insulation density and maximize heat transfer and operating life. This method of compaction increases uniformity of resistance wire spacing to help eliminate hot and cold spots. It also increases the rigidity of the element, which is an advantage in some applications. The terminal ends of these elements are re- rounded to facilitate the use of threaded fittings or other mounting methods. The heart shaped cross-section is recommended for certain heavy duty applications. It has added structural strength, achieved through die press- ing, which resists deform-ation or sagging when installed in the flow of high velocity air or thick oils and compounds, or in high surface temperature air heating.

Sheath Material — For resisting corrosion inherent in the process or environment and for withstanding the sheath temperature required— Standard sheath materials are INCOLOY ® , steel, copper and stainless steel (type 304). Other types of stainless steel, MONEL ® , titanium and INCONEL ® are available. Job Requirements — The calculation of total heat requirements for an application is outlined in Technical section. For assistance, contact your Local Chromalox field sales engineer who will be glad to contribute his judgement, experience and knowledge in solving your heating problem. After the specific heater size and rating has been tentatively selected, the watt density must be checked against the curves in Technical section. If the heater selected has a watt density higher than stipulated by the curve, consider these alternatives: 1. Use more heaters of a lower watt density to obtain the required kW capacity. 2. Reduce the kW capacity needed by reducing heat losses and/or allowing for a longer heat-up time. Watt Densities — The watt density of the element, or watts per square inch of element heated area, should be low for heating asphalt, molasses and other thick substances with low heat transferability. It can be higher for heating air, metals, liquids and other heat-conducting materials. See curves in Technical section for determining allowable watt densities. When high operating temperatures are needed, watt density must be limited in order not to exceed the maximum sheath temperature. Watt density is given in the specifications for each tubular heater. In general, a viscous material with low thermal conductivity requires a low watt density. Higher watt densities can be used with thinner liquids and with materials of high thermal conductivity. Premature loss of the element due to excessive temperature may result if the material’s heat- take-away ability is low. Also, the material may be charred, carbonized or its chemical makeup altered by overheating.

TubularHeaters Modifications

Repressed Bends — Tubulars can be bent to tighter radii at the factory. Bends are then repressed to ensure re-compaction of insula- tion for long life. Customer bending on larger radii does not require repressing. (See Factory Bending Guidelines in this section). Sheath Length — Larger diameter heaters can be made in unspliced lengths up to 40 feet. This eliminates the need for a spliced joint which is always a possible weak point that might cause premature heater failure.

In addition, titanium and other 300 series stain- less steel sheaths are available upon request. For applications requiring other materials, contact your Local Chromalox Sales office. Cold Section — Longer cold ends can be sup- plied, as required, up to 20 inches. For longer cold ends, contact your Local Chromalox Sales office. Factory Bending — Tighter bends can be made at the factory. Tubular heaters can be formed to many different shapes to suit your application. This is done by specially designed bending tools and repressing dies for bending on many different radii. Additional Features— Many additional features are available for the difficult jobs which require custom designed elements employing Chro- malox's vast engineering experience.

Round Cross Section— Highly adaptable where elements must be bent —particularly if bending is performed in the field. Triangular Cross Section — Patented process produces elements with the closest possible dimensional control. Triangulated Cross Section — Flat pressed. Patented process provides large contact area for clamp-on applications. This means more ef- ficient heat transfer, fewer elements since higher element ratings may be employed. Voltage or Wattage — Heaters can be made for operation on any voltage and rated at any wattage suitable for the application within practical limits. For voltages higher than 480V, specify high voltage terminal construction. See Component section Tubular Heater (0.475 or 1/2" diameter only). Special Wattage Distribution — Heaters can be made with higher wattages toward the end of the heated section to help offset losses in certain applications. Check with your Local Chromalox Sales office for additional information. Tubing — Standard industrial grade wall thick- ness:

TubularHeaters Customer Bending & Accessories

Customer Bending Simple element configurations can be made easily in the field from stocked tubulars listed in this catalog. If copper or stainless sheaths are selected, specify “To be fully annealed for bending.” Elements can be bent around any round, smooth surface of the right diameter. Three precuations should be observed to prevent damage to the element: 1. Radius of the round object, around which the element is bent, should be no smaller than the minimum radius for the element, as shown in the table below. 2. Sharp edges of tools should not be permitted to gouge the element sheath while bending. 3. End of cold section of the element should not fall within the bend nor come within 1/4" of either side of the bend. To locate end of cold

section, see dimensions for the element on its catalog page and determine as follows: Example — To locate end of cold section of TRI-1645 tubular element, refer to the indi- vidual product page. Sheath length: 16" Less heated length: 9-1/8" Total cold length: 6-7/8" Cold length of each end (6-7/8" ÷ 2) = 3-7/16" Terminal end bending can be done with pipe section of slightly larger diameter than sheath. A minimum 1" straight section should be left at the end. Note — To protect sheath, copper sheet can be bolted to vise jaws and end of pipe can be filed to remove sharp edge. Before bending, it is best to lay out and dimen- sion the configuration. Also, it is best to start bending from the center of the heater and work toward the terminal ends.

Brackets, Discs & Clips Brackets, Discs and Clips — Various types of brackets and clips can be fastened to the heaters to facilitate installation. The following are typical. For other brackets to meet your installation requirements, contact your Local Chromalox Sales office.
