Ceramic Sealed Infrared Heaters » Technical Specifications

Throughout the years many different forms of infrared Joule Techs have been developed. Some of the more familiar forms seen today are metal sheathed tubular heaters,  quartz heaters, quartz tubes, quartz lamps, gasfired catalytic, flat faced panels, and ceramics emitters. Each sources has its own distinctive set of Properties : 

		Metal Sheathed	Quartz Tube	Quartz Lamp	Catalytic	Flat Faced Panels	Ceramic
	Radiant Efficiency	56%	61%	86%	80%	88%	96%
	Physical Strength	High	Low	Very Low	High	Medium	Medium
	Heat-Up Cool Down	Slow	Fast	Very Fast	Very Slow	Slow	Slow
	Max. Temp	14000F	16000F	40000F	8000F	16000F	14000F
	Color Sensitivity	Low	Low	High	Low	Low	Low
	Peak Weak Length (Microns)	2.68	2.55	1.16	-	2.25 to 7.9	3 to 4
	Maximum Watt. Density	20 to 30   W / inch 2	34 W/Linear Inch.(3/8" Diatube) & 45 W/Linear Inch. (1/2" Diatube)	100 Watts Linear Inch	-	5.25 to 40 Watts/Inch 2	6 W to 44 Watts/Inch 2

	Radiant Efficiency	:	The total amount of energy that is emitted from the source as infrared radiation. The balance of heat energy from the sources are transferred via convection and conduction.
	Physical Strength	:	The physical strength of each sources. A high rating indicates a very durable sources that can with stand physical abuse such as dropping wrench on the source.
	Heat-Up/Cool Down	:	The amount of time required for the sources to come up to operating temperature and cool back down to room temperature.
	Maximum Temp.	:	Maximum Operating temperature of the sources.
	Color Sensitive	:	Refers to the ability of a typical load to absorb the special radiation emitted from a source based on the color of the load. The shorter the Wave lengths. As the temperature increases for any given source, a higher percentage of the infrared energy is concentrated in the peak wave length.
	Peak Wave Length	:	All Joule Techs radiate infrared energy over a wide spectrum of Wave lengths. As the temperature increases for any given source, a higher percentage of the infrared energy is concentrated in the peak wave length.
	Maximum Watt. Density	:	Watt density is the heat flux emanating from each square inch of the effective heating area of the elements. W/ inch 2 = rated watts / effective heating area.
