Nexthermal manufactures heaters with
better components, materials and precision...
*High watt density heaters are built with 8" long ceramic cores, 33% longer than our
competitors--resulting in fewer electrical connections on longer heaters.
*Standard stainless steel sheath is SS321 for improved corrosion resistance (Incoloy
is also available).
*New, compact right angle exit with flat sides to aid removal (when heaters last as
long as Nexthermal's do, this is important).
*Anti-seize coating applied in house for faster delivery.
*Centerless grinding option to a tolerance of +/- .0008" for a better fit.
*Computer control ed winding ensures the right wattage distribution profile on
every heater...every build.
*Technical support to understand your application and design a heater with your
specific use in mind.

High watt density heaters
The machine winding of the high watt density heater delivers the most precise
distributed wattage profile. High watt density heaters can be built to your
specifications from 1" long to over 100". Warranted to 160 watts per square inch.
Both high watt and medium watt construction can be built as an energy saving
eheat cartridge heater.
Medium watt density heaters
The medium watt density heater has a continuous resistance spiral throughout the
heater delivering unparalleled reliability. For longer heaters there are fewer internal
electrical connections. Medium watt density heaters start at 8" long, and can be
built to over 100". Warranted to 65 watts per square inch.

Specify a high watt density heater if:
*Watt density is greater than 65 watts per square inch.*
*And/or the heater is less than 8".
*And/or your application requires a precise wattage distribution.
* High watt density heaters are commonly built below 65 watts per square inch and in lengths
up to 100" long for specific applications.
Specify a medium watt density heater if:
*Watt density is less than 65 watts per square inch.
*And the heater is 8" or longer.
*And you do not need highly precise wattage distribution.
In the past only high watt density heaters could support an internal Type J or K TC. Nexthermal
