| ||
| Maximum Operating (Sheath) Temperature | Maximum operating (sheath) temperature is the highest temperature that the heater's sheath (or protective cover) may reach. This is not the maximum temperature a heated substance may reach. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Phase: | |||
| Your choices are... | |||
| Single Phase | Heaters use single-phase power. | ||
| Three Phase | Heaters use three-phase power. | ||
| 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. | ||
| |||
| AC Voltage Required | Heaters require AC voltage. Most heaters use AC voltage instead of DC voltage. | ||
| 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. | ||
| |||
| kWatts | Heating capacity is the wattage which the heater can deliver. | ||
| 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. | ||
| |||
| Watt Density | The maximum watt density that the heater can deliver. Watt density is a good measure of how quickly the heater can transfer heat to a heated surface. To calculate watt density, suppliers divide the available wattage by the heated surface area. | ||
| 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
Back to Top
|
|
| ||
| 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 | The sleeve or sheath is made of a fluoropolymer 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 | 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 | 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 | The sleeve or sheath is made of a synthetic rubber such as neoprene. | ||
| Other | Other unlisted, specialized, or proprietary sleeve or sheath materials. | ||

Insulation
Back to Top
|
|
| ||
| 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 | Heaters have fluoropolymer 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. | ||
