Rod Elements
The rod element is generally made
using .204" to .500" Dia. resistant alloy. Grades of alloy available
include 80NI-20CR, 60NI-16CR, 70NI-30CR as well as Iron Chrome
alloys with temperature capabilities up to 2350° F.
Rod heating elements are used in
applications where it is desirable to have radiant heat flow to the
internal chamber of the furnace, directly on the work. Elements may
be hung on pins or anchors from fire brick or ceramic fiber and used
above 1200° F. |

Radiant Tube
This element can be used with or
without an alloy or ceramic protection tube. The element can operate
either vertically or horizontally. Temperature range from 1500 -
1900° F. Carburizing, annealing, or hardening. 3-1/4" - 7-1/8" Dia.

Plug Heater
Elements of the plug type are
generally used in a plenum chamber with air forced through the
heater and into the work to process the work from 350 - 1600° F. The
elements can be made almost any shape to fit your duct or chamber.
The horizontal drawer type plug
heater may be used to insert into an existing duct or a plenum
chamber to add Kilowatts to your equipment. The lightweight system
enables one to install and remove the heater easily. Temperature
ranges from 350 - 1000° F. |

Coiled Elements
Coils of 1/2" Dia. wire to 16 ga.
(.051") can be produced to provide heat in the range of 350 - 2000°
F. Tempering or draw furnaces using stepped coils supported on
ceramic spools. Heat treat furnaces using continuous coils
supported on firebrick or ceramic fiber lining. |

Ribbon / Strip Elements
Ribbon elements are formed from
heat resistant alloy ribbon in shapes to fit your requirements.
Watt density of low value is obtained using ribbon rather than rod
element material at temperatures of 1100 - 2100° F.
Strip elements are formed from
1/2" - 2" wide heat resistant allow. The furnace temperatures
range from 1200 - 2000° F. Large furnaces with high Kilowatt
requirements make use of this style of element. Copper brazing,
stainless annealing. |
