Medium Wave Quartz Emitters

With Medium Wave Quartz Emitters the heating coil heats the quartz glass tube and thus activates the product. Depending on the temperature you can see a dark red up to a bright-orange glow.

In the medium and long wave infrared range quartz infrared emitters have an emission range that can be compared with ceramic emitters. The short wave radiation ratio below 3 µm, that only quartz infrared emitters have, make the difference. Thus the application ranges of both emitter types are different despite many overlappings. Due to their lower mass they have shorter reaction times and are thus recommended also for cyclical or frequently interrupted operating processes. However, Quartz Emitters are more susceptible mechanically and not suitable for dusty or chemically aggressive environments. We distinguish between cassettes and individual tubes.

Recently our EUCOPET cooperation partner for Infrared technology Ceramicx invested in a new Laser Marking System. This system allows to mark the back of the quartz standard and pillared elements with clearer and more detailed product description. The process will be rolled out on all quartz elements in the first half-year 2021.

Quartz Cassettes

FQE (Full Quartz Element) with thermocouple Quartz Cassettes

PHQE (Pillar Half Quartz Element) Quartz Cassettes

QQE (Quarter Quartz Element)

Quartz Cassettes generate usable wave lengths between 1.5 and 8 µm and thus emit a glow during the operation. The cabinet is made of aluminized steel and has excellent reflection characteristics.

The mounting is normally done via M5 threaded bolts. In order to reach a compatibility with ceramic emitters the quartz emitters can be manufactured with a terminal block.

The cassette typically includes seven tubes. A thermocouple can be installed in the middle tube upon request.

Quartz Glass Tubes

Our medium wave infrared quartz glass tubes are custom-built. They are for example used in toasters or radiation platens in drying systems. As shown in the picture there are different connecting options. Quartz glass tubes are available as light or dark emitters and are only suitable for horizontal operation.

STQH Emitters

STQH Emitters are bent quartz glass tubes that are usually used in infrared platens at thermoforming processes. The usable emitted wave length is 1.5 – 8 µm. They always have to be installed horizontally. Special holders for the emitters can be supplied.

Thermocouple

We can also install a thermocouple into the quartz cassettes. It will be mounted in the middle of the seven quartz tubes. Usually it is a thermocouple type K (NiCr-Ni), however, type J (Fe-CuNi) is possible as well. A thermocouple cannot be installed in quartz glass tubes and STQH emitters.
