R-12K and 1200°C when powered with 20 watts for the ASB-IR-18K.
The radiating element of the ASB-IR-12K is a coil of resistance wire which
has a high emissivity in the Infrared spectral region. The coil is supported
on a grooved cylindrical substrate of alumina, resulting in the windings
being electrically insulated from each other. This contributes to a more
uniform radiating source. The unit does not require operation in a sealed
atmosphere. The header is fabricated from cold-rolled steel. The support
pins are hermetically sealed in glass.

The ASB-IR-18K is designed for those customers who require higher
temperatures and greater output from their
infrared source. These emitters are manufactured using a patented
silicon nitride material. The advanced ceramic
technology ensures a very stable product. Their robust design ensures
intrinsic physical and thermal strength. When operated at 12 volts/20
watts the ASB-IR-18K reaches 1200°C. These silicon nitride emitters
are mounted in a 1 inch parabolic reflector for extremely efficient
collimation of energy. This unit is our highest output IR product.
