Dehumidification during storage, dispatch and transport

Professional dehumidification concept protects goods

End-to-end dehumidification concept from raw materials warehouse to transport

In the silo as well as during transport hygroscopic bulk material is endangered by humidity – this holds true for both the chemical and the pharmaceutical industry. Humidity continues to be a problem after production, because the products are mostly packed into damageable cardboard boxes with paper inserts. Therefore, dehumidification also plays a key role for storage, dispatch and transport.

Medicine, dragées or powders – humidity already poses a risk to chemical and pharmaceutical products when in the raw materials warehouse or silo: If moisture enters the goods can go lumpy, become caked or spoiled. Even when produced and stored properly in a dry space, the next moisture issue is imminent in the packaging. It mostly consists of cardboard boxes soaking already at a relative humidity value of 55 per cent. Including labels. In the worst case scenario the packaging absorbs water in the manufacturer's warehouse or during transport – long before it arrives in the pharmacy or drugstore.

An end-to-end dehumidification system is imperative to be able to deliver the packages in impeccable dry condition, which also includes the staging area and transport. We at Trotec develop a master plan for the dehumidification using adsorption dryers.

Adsorption dryers of the TTR series as mobile and stationary dehumidifiers

In order to ensure the constant dehumidification during storage, dispatch and transport, we often utilize adsorption dryers of the TTR series for our customers in the chemical and pharmaceutical industry. These dehumidifiers are available in numerous model variants and with two separate air flow ducts (TTR Trisorp Dual principle of operation) characterized by an especially simple adjustability. Moreover, with their internal heat recovery and high level of resilience and performance of the special rotors they rank among the most economic dehumidifiers of their kind. Both desiccant dehumidifiers of type "D" – TTR 400 D and TTR 500 D – are as standard equipped with the innovative Duoventic air volume regulation. The TTR series comprises stationary as well as mobile adsorption dryers. You can recognize the stationary devices in the product overview (below) by the 4-figure model numbers, the mobile devices bear 3-digit numbers.

Drafting and test run: make use of our industrial services

For the chemical industry and pharmaceutical production the Trotec Group not only supplies devices for dehumidification related to hygroscopic bulk material and packaging. In consultation with you we also develop the dehumidification concept for storage facilities, dispatch areas and transport. Furthermore, the industrial services team provides mobile dehumidifiers to test the concept beforehand in trial operation. Only after measurements have proved that the humidity level can be controlled as desired will your final solution be launched.

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 962-777 – 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.

  • Dehumidification in fertilizer storage facilities

    The production of hygroscopic materials in the chemical industry requires intuition and sure instincts. After all, the substances love water and readily absorb the moisture contained in the ambient air. And this can have disastrous economic consequences. As it binds water, the material starts sticking together and clumping, and may become unusable in the worst case. One example are fertilizers. If...

  • Dehumidification in timber yards

    In the past, when storing wood it had been rather a challenge to keep the moisture of furniture wood below the required 9 per cent, for example: If no dehumidifiers are used, seasonal temperature differences and fluctuations in air humidity cause the wood moisture to rise. This considerably affects timber quality and results in problems during processing and even in reject.
