Tubular Heaters Specifications

Element Options


	Element Options:
	Your choices are...
	Single Ended		The single-ended tubular design places both terminals at one end.
	Double Ended		The double-ended tubular design places terminals at each end of the tube. This design is well-suited for bending.
	Round Heating Element		The base heating element is round.
	Flat or Triangulated Heating Element		The base heating element is flat or triangular.

Dimensions of Heating Element


	Heated Length:		Enter the heated length for a band, cartridge, ceramic fiber, strip, immersion, over-the-side, radiant, flat or flexible heater. Enter the height for a duct heater.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Width / Diameter		Enter the heated width for a duct, flat, ceramic fiber, strip, flexible, flat panel, or radiant heater. Enter the diameter for a cartridge heater, cylindrical ceramic fiber heater, tubular heater, or radiant element. For a band heater, enter the inside diameter.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

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.

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.
	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.
