Coil Heaters and Cable Heaters Specifications

Physical Specifications


	Heater Geometry Options:		Formed heaters are available in a variety of shapes. Some of the more common shapes are listed below.
	Your choices are...
	Coiled Round Cable		Coiled round cable heaters are sometimes called close wound coil heaters.
	Sinuated		Sinuated or formed heater cables are low-profile heaters used to generate high temperatures in restricted areas.
	Spiral Wound		Spiral wound heaters are low-profile heaters used to generate high temperatures in restricted areas.
	Star Wound		Star wound coils are offset coils used to create a turbulent flow in air or fluid. The flowing media has better contact with the heater surface. Typically, star wound coils are inserted into pipes or ducts.
	Straight Cable		The heating element is straight. All other heater configurations are based on this initial, uncoiled state.

Sleeve (Sheath) Material


	Sleeve (Sheath) Material		Most heaters have a protective sheath or sleeve that covers the heating elements. There are usually many choices for sheath or sleeve material.
	Your choices are...
	None		The heater has a bare, exposed heating element without a sleeve or sheath.
	Aluminum		The sleeve or sheath is made of aluminum, a bluish, silver-white, malleable, ductile, light, trivalent, metallic element that provides good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
	Brass		The sleeve or sheath is made of brass, an alloy that provides good strength, excellent high temperature ductility, reasonable cold ductility, good electrical conductivity, excellent corrosion resistance, and low magnetic permeability.
	Copper		The sleeve or sheath is made of copper, a common, reddish, metallic element that is ductile and malleable. Copper is one of the best conductors of heat and electricity.
	Fluoropolymer (Teflon®)		The sleeve or sheath is made of a fluropolymer such as Teflon^® (DuPont Dow Elastomers). Teflon refers to a class of fluoropolymer resins used for a wide variety of commercial applications. They are highly-resistant to temperature, chemical reaction, corrosion, and stress-cracking.
	HT Foil (Ceramic Foil)		The sleeve or sheath is made of high temperature (HT) foil. HT foil is sometimes called ceramic foil.
	Iron		The sleeve or sheath is made of iron.
	Nickel Alloy (Inconel®, Incoloy®, Monel®)		The sleeve or sheath is made of nickel alloy. The amount of nickel varies by alloy type. Proprietary alloys include Inconel^®, Monel^® (Special Metals Corporation) and Incoloy^®(Inco Alloys International).
	Polyimide (Kapton®)		The sleeve or sheath is made of a polyimide such as Kapton^® (DuPont).
	Rubber		The sleeve or sheath is made of natural or synthetic rubber, silicone, or styrene butadiene (SBR).
	Stainless Steel		The sleeve or sheath is made of stainless steel, a chemical and corrosion resistant alloy that can have relatively high-pressure ratings.
	Steel		The sleeve or sheath is made of steel, a commercial iron that contains carbon in any amount up to about 1.7% as an essential alloying constituent. Steel is malleable under suitable conditions and distinguished from cast iron by its malleability and lower carbon content.
	Synthetic Rubber (Neoprene)		The sleeve or sheath is made of a synthetic rubber such as neoprene.
	Other		Other unlisted, specialized, or proprietary sleeve or sheath materials.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Insulation


	Insulation Options		Heater insulation reduces heat loss to the environment. Some heaters may be available with multiple insulation options.
	Your choices are...
	No Insulation		Heaters do not have insulation. They have a lower profile and are useful in areas where space is at a premium, but are not particularly energy efficient.
	Ceramic Insulation		Heaters have ceramic insulation. Ceramics consist of nonmetallic minerals, such as clay, that are permanently hardened by high-temperature firing. Most ceramics resist heat and chemicals.
	Magnesium Oxide		Heaters have magnesium oxide insulation.
	Mica Insulation		Heaters have mica insulation. Mica consists of colored or transparent mineral silicates that are crystallized in monoclinic forms and readily separated into very thin leaves. Mica is valued for its electrical insulating properties and resistance to heat and acids.
	Mineral Insulation		Heaters have mineral insulation.
	Fluoropolymer (Teflon®)		Heaters have fluropolymer insulation made of materials such as Teflon^® (DuPont).
	Fiberglass Insulation		Heaters have fiberglass insulation. Fiberglass is strong, durable, and impervious to many caustics and extreme temperatures. Fiberglass fabrics are used widely in industry.
	Other		Other unlisted, specialized, or proprietary insulation options.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Features


	Features
	Your choices are...
	Corrosion Resistant		The heater is made of corrosion-resistant materials and suitable for use in a corrosive or chemical environment.
	Cryogenic Use		The heater may be used in a cryogenic environment.
	Custom Design		The heater can be custom-designed and configured. Custom designs are configured in coordination with the manufacturer.
	Dynamic Power Regulation		Dynamic power regulation regulates the power output from the heater so that parts are heated at the proper rate.
	Explosion-Proof		The heater's housing is designed to withstand explosions and protect the materials within. Some suppliers include heaters with housings that can withstand sparking and flames.
	Encased Coil		The coil is encased in a casting for protection and to maximize heat transfer.
	Finned		The heater has fins for better heat dissipation.
	Grounding Wire		The heater is equipped with a grounding wire.
	Hazardous Location		Hazardous location heaters are designed for use in places where there is a risk of fire or explosion. Underwriters Laboratories (UL) and other organizations rate these devices.
	Indirect Fired		Indirect fired heaters use a secondary heat exchanger to separate the breathable air stream from the combustion air stream.
	Internal Temperature Detector		The heater is equipped with an internal temperature detector.
	Microprocessor Controlled		The heater is equipped with a microprocessor that controls the voltage applied to the heated object. The microprocessor regulates the temperature of the heated object, as well as the speed at which the object heats.
	Multiple / Independent Timing Controls		Heaters have separate, independent controls for multiple functions such as heating, cooling, temperature hold, or other heater parameters.
	Overheat Protection		Heaters include an automatic shut-off or other mechanism to prevent overheating of the material.
	Portable		Portable heaters are lightweight or have wheels.
	Thermostat		Heaters have an integrated, adjustable or preset thermostat.
	UL Approved		Heaters are approved by Underwriters Laboratories (UL). Typically, documentation of UL certification is available from the manufacturer.
	Weatherproof Housing		The heater's housing is sealed, liquid-proof, and suitable for use in a harsh, outdoor environment.
