Dehumidification in cleanrooms and drying rooms

The objective: avoiding electrostatic charge at all costs

In the production of electronic equipment and semiconductors humidity can lead to electrostatic charge. For this reason, sensitive processing steps are being performed in cleanrooms and drying rooms. The mobile adsorption dryers of the TTR series are ideal for these high requirements during dehumidification.

At present the electronics and semiconductor industry is the sector putting the highest requirements on dehumidification in cleanrooms. For instance, a manufacturer of lithium-ion batteries asks for a relative humidity of only 2 per cent. A rather extreme value when compared with the average 10 per cent in the pharmaceutical industry or the 35 per cent in the automotive industry. To achieve such a high dehumidification perfectly adjustable, constantly working dehumidifiers are required.

Duoventic: individual vernier adjustment of humidity level and volumetric flow

The stationary and mobile adsorption dryers of the TTR series – by use of one of the three variations of the TTR functional principle – ensure a high dehumidification performance while simultaneously keeping the energy consumption low. Both mobile adsorption dryers marked with "D" for the Duoventic air volume regulation, TTR 400 D and TTR 500 D, provide maximum flexibility when adjusting the required amount of dry air. Owing to the innovative Duoventic air volume regulation  both fans of the separate air circuits can be controlled independently via an infinitely variable electronic regulation. This enables an individual vernier adjustment of humidity level and volumetric flow of the required dry air and thus a precisely controlled percentage of relative humidity. TTR 400 D and TTR 500 D were designed for use in small cleanrooms or drying chambers.

Adsorption dryers TTR 800 to 13500 for large drying rooms

Large drying rooms and cleanrooms can ideally be dehumidified by use of the stationary adsorption dryers serially numbered from TTR 800 to TTR 13500. They come equipped with the Monoventic control for the regulation of dry air. Another option is the Flowmatic control by use of which the volumetric flow of the dry air is kept constantly.

Reliable measurement technology and data loggers "made in Germany"

The electronics and semiconductor industry has to depend on extremely reliable measurement technology to keep a single-figure relative humidity value constant. Trotec, for instance, supplies the thermohygrometers T210 and T260. Furthermore, the data loggers of the MultiMeasure Professional series, DL200H or DL200X, manufactured in Germany, provide manifold opportunities for tamper-proof long-term measurements during dehumidification.

Consultation and mobile testing appliances: make use of our industrial services

For the electronics and semiconductor industry the Trotec Group not only supplies dehumidifiers and measurement technology, but also technically and economically ideal solutions for climate conditioning. Our specialists in the industrial services team calculate all climate parameters and recommend the suitable devices. Moreover, we have mobile units on offer which can be used to test the planned dehumidification of your drying room in advance. This way, you can be sure that the proposed solution actually works.
