Desiccants as part of the process

We can't find products matching the selection.

Desiccants are applicable almost universally. In addition to containers, transport, packaging or storage, they are also used as part of the production process in many companies. ThoMar OHG offers you desiccants in various formats and chemical compositions. Thus Silica Gel for standard requirements can be ordered directly from our shop. However, if required, it is also available in particularly fine grinding grades or high purity grades. Have you not found yet what you are looking for on our website for your special application? Just give us a call and tell us your ideas where and how you want to use desiccants. We will find a solution together with you!

Protecting wind and water power stations from moisture

Especially in the offshore, onshore and hydropower sectors, the climatic conditions due to humidity are extreme not only during plant operation, but even before commissioning. The temperature fluctuations between day and night can be enough for the humidity to repeatedly exceed a critical level.

ThoMar OHG has already gained experience with customers from the wind power sector. Damage to sensitive components caused by high humidity is not uncommon here and must be avoided at all costs. A simple and effective solution to this problem is the use of a desiccant that is suitable for the respective application.

Even before commissioning, desiccants protect wind turbines
from moisture damage.

Examples for dehumidification

With our wide range of desiccants, we can cover almost all areas and process steps for your needs:

Preservation of packaged parts with desiccant bags according to DIN 55473
Drying offshore wind turbines until commissioning with SeaDry - our high-performance desiccant on a salt-starch basis - effectively protects against moisture even during transport and (interim) storage
Silica gel orange for operating transformers in wind and hydroelectric power plants - ensures filtered and dry air supply in the plants / generators

Silica gel is used for running transformers of hydropower plants.

Use of SIlica Gel in Drying Plants

Particularly in the case of highly hygroscopic powdery products, such as food supplements, it is important to maintain a constant low level of humidity during the manufacturing process. If possible, the ambient air within the closed filling area of the machines should contain no more water molecules. Here, manufacturers use the method of sorptive air drying. Silica gel is regarded here as a highly effective technical adsorbent. Due to its molecular structure, it binds large amounts of moisture and is regenerable. This means that it also releases moisture again when dried with heat (desorption).

Silica Gel is used in industrial drying plants.

Unwanted Product Smell caused by Condensation

During the production of spectacle cleaning sets, our customer was faced with a risk of condensation within the packaging, which is also a product component, due to the production process. The consequences were a unwanted smell of the enclosed textile cloth and a clammy feel of the paper operating instructions. Since the addition of a Desi Dry silica gel packets to the plastic container serving as packaging directly during the production process, condensation no longer occurs. Odour and feel of all product components again meet the high quality requirements of our customer.

Silica gel packets prevent musty product smell.

Flower Drying with Silica Gel

Especially flowers with colourful blooms are dried quickly and colourfast by a ThoMar customer with the help of silica gel. Silica gel, consisting of silicon dioxide, extracts water from the plant and thus ensures that bridal bouquets, for example, remain beautiful for a long time to come.

With the help of silica gel bouquets can be preserved.

Condensation in Floor Lights

Lamps that were firmly installed in the ground heat up during operation. The process of cooling down lets a vacuum form within the body of the lamp, and the ambient - possibly humid - air is drawn into it. Neither air nor humidity can escape, so the humidity condensates at the walls of the lamp body. To prevent this, silica gel packets (e.g. Desi Dry from ThoMar's range of goods) can be placed in the lamp body, which absorbs the excessive moisture.

Silica gel packets prevent condensation in floor lights.

Use of Desiccants in Bridge Pillars

The Oeresund Bridge and other bridges leading over stretches of water are highly exposed to the surrounding elements. There are always cavities in the base of the ferroconcrete piers. Lying underwater, the prevalent condition here is a humid climate. The operators of the bridge need to regularly replace the desiccants fitted into the pier base in order to keep humidity at a level that is innocuous for the structure of the bridge.

There are desiccant pouches fitted into the pier bases.

Drying of Intermediate Bulk Containers

When transporting liquids or fluid substances, e.g. foodstuff, cosmetics, and chemicals, people use so-called IBC (intermediate bulk containers). After cleaning and before refilling the IBC, they need to eliminate the residual damp within the container. The drying process can be accelerated by desiccants.

Example of use intermediate buk container

Drying of IBCs through desiccants.

Desiccant Plugs for Tablet Tubes

In order to ensure a constant quality of the products concerned even at changing temperatures and humidity levels, manufacturers of pharmaceuticals and foodstuffs use so-called desiccant plugs. These are used to seal tablet tubes, for example. ThoMar OHG supplies an international manufacturer of packaging and packaging components for food products with ultra-fine, microporous silica gel, which is then inserted into the lids of effervescent tablet packaging.

Silica gel in the packaging lids keeps effervescent tablets dry.
