Ceramic-E-Mitters

Construction Styles

Solid Curved Face

These ceramic e-mitters come in 5 sizes. They utilize a metal reflector to direct the heat to the application.

Solid Flat Face

These ceramic e-mitters come in one size, 120 mm x 120 mm.

Insulated Flat Face

These ceramic e-mitters come in 4 sizes. They contain insulation that keeps the heat generated towards the application and reduces reliance on reflectors in the installation.

Linear Housings

Linear Housings can be designed with custom configuations using any combination of Ceramic E-mitter Series necessary. They are available in preconfigured sizes or Tempco can design a custom heater to suit your application.

Arrays/Panels

Array Housing Assemblies can be designed with custom configuations using any combination of Ceramic E-mitter Series necessary. They are available in preconfigured sizes or Tempco can design a custom heater to suit your application.

Edison Style Bulb

These hollow ceramic heaters have a unique thin wall construction and geometrical shape to facilitate fast heating and cooling rates.
The resistance coil is embedded into the specially designed circular ceramic E-mitter surface, providing extremely uniform heat transmission with low element surface temperatures.
Because of the convenient Edison Screw-In style termination, CRE & CRR E-Mitters are recognized as a tremendously versatile source for localized spot heating. They can be used virtually anywhere quickly and easily by simply installing the CRE E-Mitter into common porcelain/ceramic insulated bulb sockets—like any ordinary light bulb.
