What are ceramic Elstein Infrared Heaters?

What are ceramic Elstein Infrared Heaters?

Elstein ceramic Infrared Heaters are electrical Heating Elements consisting mainly out of a technical ceramic being high-temperature resistant.

What's the application for Elstein Infrared Heaters?

What's the application for Elstein Infrared Heaters?

Elstein IR Heating Elements are used for an endless number of heating and drying applications. You find a selection of IR heating and drying applications on our Website. For determining if Elstein Electric Heating Elements can be used for your application we provide consulting and test devices. If required we do heating and drying tests in our laboratory, too.

What's the wavelength of an Elstein Ceramic Heater?

What's the wavelength of an Elstein Ceramic Heater?

Elstein Electric IR Emitters provide only the non-visible infrared radiation and no visible or rather hardly visible light. The emitted infrared radiation covers the medium and long-wave infrared range of 2 - 10 µm.

What are Dark Radiators?

What are Dark Radiators?

Dark Radiators are Heating Elements which do only or mostly emit non-visible infared radiation. Ceramic Elstein Infrared Heaters belong to Dark Radiators because they do not emit visible light, resp. they shimmer reddish under high performance.

Can Elstein Infrared Radiant Heaters be controlled?

Can Elstein Infrared Radiant Heaters be controlled?

A large number of Elstein IR Radiant Heaters can be supplied with a thermocouple which is embedded in the radiation surface. In connection with our TRD 1 Temperature Control Units and TSE Power Switches the temperature of the heaters can be controlled with an accuracy of +/- 1 °C. It is also possible to use proprietary power controllers or dimmers.

How long is the service life of an Elstein Infrared Emitter?

How long is the service life of an Elstein Infrared Emitter?

The durability is primarily influenced by the temperatures reached during use.

For example, an HLS at 1100 °C in continuous operation has an average service life of 2000 hours. An SHTS with 900 °C on the other hand reaches already about 8000 hours. Heaters with a low wattage often reach more than the double of this lifetime.

Heaters of the Elstein MaxLife Series have a typical service life of 35000+ hours.

On the other hand, there are applications in which the heaters can fail after 1000 hours due to materials, which attack the heating coil or the ceramic. Such materials are, for example, chlorine, fluorine, hydrofluoric acid, sodium hydroxide, nitrogen and peroxide.

Do Elstein Infrared Emitters fulfill Cleanroom requirements?

Do Elstein Infrared Emitters fulfill Cleanroom requirements?

Yes. For decades Elstein IR Radiant Heaters have been used in clean rooms class 100 or even better.

They are used in semiconductor production, in the pharmaceutical industry and in manufacturing picture tubes. Elstein Infrared Radiators are also used in the production of modern TFT displays.

What is the optimal distance between Infrared Radiators and the material exposed to heating?

What is the optimal distance between Infrared Radiators and the material exposed to heating?

In the case of heat-sensitve material (paper, thin foils) the radiation distance should not be less than 50 mm. If the radiators are not mounted densely next to each other, the distance must be larger if the materials to be heated are stationary. If the distance between radiators is 3 - 4 cm, a distance between radiators and goods of 15 - 20 cm is required in order to achieve uniform heating.

In practice a distance of Heater to Material of 5 - 12 cm is chosen in most of applications.

Can metals be heated with Ceramic Radiant Heaters?

Can metals be heated with Ceramic Radiant Heaters?

Bright metal shows a relatively weak absorption of infrared radiation. However, corroded, roughened, coated, enamelled or painted metal can reach an absorption rate of more than 90%.

Can Elstein Ceramic Emitters be used inside a vacuum?

Can Elstein Ceramic Emitters be used inside a vacuum?

Yes. Elstein Infrared Radiators can be used inside a vacuum. Excepted from that is the High Performance Heater HLS, only.

Are Elstein Infrared Heaters susceptible to splash water?

Are Elstein Infrared Heaters susceptible to splash water?

During hot state Elstein Infrared Heaters are splash resistant. If the radiators get in touch with water when they are cold, they must subsequently dry at a low temperature (max. 80°C) for a few minutes.

Questions concerning health?

Questions concerning health?

Elstein Infrared Radiation Elements are successfully used in Infrared Saunas and Therapeutic Equipment.
