Dehumidifiers in the steel industry

Professional solutions for all work steps

In the steel industry there are a range of processes requiring the separation of liquids and the discharge of moisture. One example is the production: chemical losses and emissions are reduced by means of a droplet separation. What is more, a systematic dehumidification protects the plants and important components from corrosion. For storing steel products a certain level of humidity should be observed also, so that corrosion and oxidation cause less trouble for the products. Trotec offers ideal solutions for a fine-tuned drying process in all fields of the steel industry –as permanent systems or hiring models.

When it comes to the reduction of chemical losses and emissions as well as an optimized product storage, it is vitally important to adhere to a low humidity level during the production in the steel industry. An example is the operation of a pickling plant handling chemicals to treat the steel with. Already during the production of the steel products certain humidity values must not be exceeded so as not to compromise the process and in order to protect the partly sensitive machines against the harmful moisture.

Ideal storage conditions

A low humidity level is also indispensable when storing steel products. Otherwise there is a risk of oxidation and corrosion at the cold surfaces where moisture accumulates, which at worst even renders the products unusable. Steel begins to corrode at a relative humidity of about 50 per cent. If the relative humidity exceeds 50 per cent, the oxidation rate is up to 2000 times higher than with a low humidity level. So, for one thing, you are to avoid the usage of water near storage facilities, and for another, to ensure an active an above all effective dehumidification. This not only serves to maintain the high quality of the metal products, but also to reduce the amount of rejects.

Protecting sensitive equipment and machinery

Besides the stored steel products other equipment such as compressors, turbines and gas turbine filters should also be protected against moisture and consequently corrosion. An inappropriate humidity value affects them badly, for machines love dry air. Unlike humankind machines and production facilities prefer extremely dry air. For that is the only way to avoid the problematic corrosion.

Strong dehumidification partner

Liquid drops accrue wherever gases or fluids are separated. And as a rule they bring about considerable technical difficulties in the production. In order to secure the productivity of entire plants and to prevent an increased reject rate, Trotec provides highly efficient solutions for dehumidification: the stationary TTR industrial desiccant dehumidifiers. Naturally, they also ensure an effective dehumidification of complete storage facilities for an all-round protection of the products from moisture. The humid air is led through a rotor and its hygroscopic surface adsorbs the moisture. The dried air is then released to the storage space.

Current climate values at one glance

To be on the safe side at all times humidity values can be measured quickly and reliably in all areas of a steel plant. The moisture measuring devices and especially the climate data loggers made by Trotec are excellent and precise measuring devices for the determination of climatic details.

Make use of Trotec's best practice industrial services

Since every industrial undertaking has characteristic process flows, installations and facilities, every air treatment solution demands case-specific device configurations. All in all, the combined effects of air currents, humidity conditions and temperature fluctuations are often hard to calculate on a purely theoretical basis, e.g. in airlock areas or on conveying paths. The consequence: Unnecessary additional costs due to an overestimated demand or – even worse – solutions not working sufficiently in real life.

You can count on our experts

In order to precisely calculate the demand in the industry and to develop tailor-made concepts for climate conditioning experienced climate specialists are needed. Rely on our team of experts as well as the industrial services: We analyse the individual requirement situation with you present on site, determine the specific demand for devices and develop a tailor-made project solution right up to the exact positioning of the devices.

Before the planned stationary units are installed, our service team first works with mobile versions of the drying units as part of a trial run. These can be put up without any difficulty or the need for structural changes.

During this validation phase we document all relevant climate parameters such as air temperature, relative humidity, dew point or flow rate for a final optimization of the requirement calculation.

Trotec is the only provider of this advantage:

Thanks to the unique option of non-binding trial operation you will invest solely in solutions which have verifiably proven their worth in everyday operation meeting your individual on-site requirements. The stationary units will not be ordered until you are fully satisfied with our concept. The only costs incurred consist of an inexpensive hiring flat rate for the time of test operation.

Just give us a call at +49 2452 963-777 – our industry consultants will be pleased to help you personally and provide information regarding our best practice industrial services. Or send a request indicating your personal requirements directly to our industry experts. We will answer promptly!

Upon request, we also produce customized desiccant dehumidifiers as special models

Upon request, we will readily produce tailor-made desiccant dehumidifiers as special models “made in Germany” perfectly geared to your needs, e.g.:

  • TTR industrial desiccant dehumidifiers with hygienic design
  • TTR industrial desiccant dehumidifiers for PWIS-free dry air
  • TTR industrial desiccant dehumidifiers with extremely low dew point

Makes use of the possibility of having special models with tailored components for your individual needs planned, designed and manufactured in close consultation with our specialists.

Trotec products for the steel industry

Application examples for the steel industry

  • Drying compressed air

    The most frequent causes for a production stop are too much water vapour in the machines and installations, and corrosion inside the pipelines. Therefore, too humid compressed air should be avoided by all means. An effective option is the use of high-performance dehumidifiers. The answer to the question of how dry the compressed air has to be in order to guarantee optimum production conditions and...

  • Cable repair

    In the industrial sector, cables are often exposed to the toughest environmental conditions. Consequently, defects occur causing an interruption of the necessary power supply – in many cases for a longer period of time. To avoid serious production losses or to perform maintenance work as quickly as possible, cable breaks and defects are located with the help of infrared thermography. Cables used...
