Dr. Fischer 14144Z/98 – 3000 W 400 V SK15s Short-Wave Infrared Halogen Lamp with Reflector

Dr. Fischer 14144Z/98 is a special industrial short-wave infrared halogen emitter rated at 3000 W and 400 V. Infrared radiation transfers energy directly to the material being heated, providing an extremely fast heat-up response without the need to heat the surrounding air first.

The lamp uses a quartz tube with a diameter of 11 mm and incorporates a white reflector. The reflector directs a larger proportion of the infrared radiation towards the working area and reduces radiation emitted in the opposite direction.

Technical documentation for the 14144Z/98 specifies a total lamp length of 355 mm and a heated length of 280 mm. The lamp is equipped with 200 mm leads and is designed for horizontal operation. Its rated service life is 5,000 hours.

The lamp operates as a short-wave IR source. It should not be described by a single wavelength, as the heated tungsten filament produces a continuous radiation spectrum. The documented filament colour temperature of approximately 2650 K is an important parameter affecting its spectral distribution and high proportion of short-wave infrared radiation.

The 14144Z/98 is intended primarily for industrial process heating, including plastics and PET processing, preheating of materials before forming and other production processes requiring rapid and precisely directed radiant heating.
