Power Requirements and Outputs
   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.
   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.

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. 
   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.

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       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. 
   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.
