Elstein HLS: Ceramic Infrared Rod Heaters
More Information
Elstein Infrared Heaters
Elstein HLS high performance heaters are ceramic infrared rod heaters, which can be used for operating temperatures up to 1000 °C and surface ratings up to 87 kW/ m².
HLS Series heaters have a gold-plated ceramic parabolic reflector and transfer up to 80% of the energy supplied as infrared radiation to the material to be heated.
Elstein HLS high performance heaters are available in two designs with
750 W / 230 V and for pairwise serial connection with 375 W / 115 V.

Features of HLS ceramic rod heaters
HLS heaters allow material temperatures of up to 700°C or high throughput speeds. The typical operating temperature of
1000 °C is reached in less than one minute.
HLS Series heaters are therefore particularly suitable for use in plant construction in which special solutions have to be drawn up for the customer's specific needs and for applications requiring high outputs.

Elstein HLS Series Ceramic rod heaters: Dimensions
Elstein HLS radiators must be operated with temperature control to avoid damage due to overheating. The power can be controlled using proprietary sheathed thermocouples as well as Elstein platinum-thermocouples (both type S, Pt-PtRh) in conjunction with temperature controllers, thyristor switching units and further accessories.
IR radiation areas can be assembled using MPO mounting profiles. The national safety regulations must be complied with for the respective application, for example, the IEC or EN standard 60519-1, Safety in electrical heating installations.
Our instructions for mounting, operation and safety must be observed.
Typical industrial applications for ceramic infrared heaters
Infrared heat is an excellent non-contact heat source and is thus used in applications involving delicate surfaces, for pre-heating, softening, curing and drying.
