Short Wave Quartz EmittersDownloads

Short Wave Quartz Emitters are the infrared emitters with the highest radiation intensity (up to 20 W/cm²). They consist of coiled tungsten wire within an air-tight quartz glass filled with inert gas. Depending on the requested emission range, differently coiled heating coils are used. We also supply various holders and connections as required.

Heating and cooling times last only a few seconds. Thus these heaters are most suitable for applications with short cycle times that have to be either started or cooled down quickly.

Reflectors made of aluminised steel sheet are available matching the emitters. To adjust the radiation even more accurately to the target material the glass can also be equipped with a coating made of ceramics or gold on the rear.

The standard products that can be supplied within a short lead time are shown in the tables below. Starting at 25 pieces we are pleased to manufacture special emitters upon your request. We can also manufacture twin tube emitters with a one-sided connection. Moreover, these twin tubes have a higher autostability which allows for a longer length of tube. We can also bend the emitters with a minimum bending radius of 20 mm (twin tubes: 150 mm) according to your specifications.

These emitters are generally designed for horizontal installation positions. A diagonal or vertical operation of the emitter is possible via a special support of the heating coil at the quartz glass (see our Installation, Handling and Safety Information).

Emission range Quartz Emitters QHM vs. QTM The high light ratio can also present some issues in some applications. Ruby-coloured glass therefore shades the light ratio without influencing the infrared radiation output.

In order to optimize the lifetime of the emitters and reflectors we recommend an air cooling operation. Temperatures above 350 °C in the areas of the element's cold ends should be avoided in any case.

With Quartz Halogen Emitters the tungsten coil is kept in the middle of the quartz tube by means of distance clips. This distance to the glass is necessary as the heating wire can reach up to 2600 °C. Due to the high coil temperature these heatings emit up to 5 % radiation in the visible range (yellow to white light). We recommend installing the emitters so that they are shielded from plain sight. In the standard version the emitter may only be operated horizontally. Emitters for the vertical operation can only be manufactured upon request.

Quartz Tungsten Emitters

Quartz Tungsten Emitters

A star-shaped heating coil supports itself at three points in the glass of the Quartz Tungsten Emitters. This makes for excellent structural stability. The direct contact with the glass is only made possible because the heating coil's temperature does not exceed 1500 °C. At the same power considerably more heating coil is used than at emitters with a supported coil. Thus the emitted radiation is not that short-waved. Furthermore, a ratio of visible light is radiated. However, this is more in the orange to dark-yellow range.

FastIR 305

A standardized unit for using quartz halogen or quartz tungsten emitters is the FAST-IR unit. The reflectors are installed in a light-weighted but sturdy cabinet with integrated aeration. The units can be used in a variety of versatile applications: from paint drying to pre-heating of foils up to printing or thermoforming of textiles, leather and synthetic leather in the furniture and automotive industries.

Both short-wave emitter types, quartz halogen with supported coil or quartz tungsten with star-coil can be used in our Fast-IR units.

The installed axial fans are designed for continuous operation. Besides cooling the reflectors and emitters the directed air stream also serves for evacuating humidity and gases arising from applications that would disturb the heating process.

In addition to the standard sizes we also manufacture various unit dimensions on request. For larger systems several Fast-IR units can be strung together.

Control

Control For the short wave quartz emitters a PLC-based control with high-performance semiconductor relays has been developed. Besides the standard control technology it is also equipped with a preheating programme for the emitters, a standby-control as well as an after-running control for the FAST-IR units' fans. It can also be controlled via a time-preset. The LC-display guarantees a high ease of use.
