Your Benefits

Medizinische Instrumente nach Oberflächenreinigung

Low temperature for gentle processing

Your product is sensitive and require very gentle processing. In terms of drying, this is achieved by highly efficient dehumidification at low temperatures between 20 °C und 90 °C as required for the specific application. This absolutely stress-free low temperature drying prevents undesired heating of the materials and products.

High process reliability

Drying with Airgenex^®med in the closed system ensures constant parameters, such as temperature, time, humidity, air speed and airflow rate, and makes your process independent of ambient environmental conditions. The drying system operates reliably, stabilises your production flow and, as a result, optimises your process. Airgenex^®med is the answer to any quality issue in the drying process.

Independent Technology

Airgenex^®med drying does not entail any interchange with ambient air. The system is emission-free and does not impair clean-room and production environments. Also, Airgenex^®med drying systems are independent of the plant infrastructure.

High Efficiency

The use of heat pump technology for air dehumidification makes Airgenex^®med highly efficient. Top quality drying results at short times are achieved by a perfect combination of air conditioning and air routeing fine-tuned to suit the requirements of the specific product.

Drying Systems

for pharmaceutical and medical Applications

We develop, design and manufacture drying systems both for batch and continuous operation. We modify our technology to meet your specifications. All drying related parameters for your specific application are determined by prior tests in our test center.

For drying to be successful, a perfect match of air dehumidification and air routeing is required. Extremely dry, unsaturated air, at low temperatures, is routed exactly to the place where humidity is to be absorbed. This process – our heat pump based condensation drying – is applied in various types of system designs.

Hygienic Design und GMP/GAMP

Our drying systems are made from stainless steel and fulfil hygienic design cleaning requirements. We shall be pleased to meet your specific GMP requirements – as a complete package or as an individual service. Just tell us what you need!

Bags and Bottles for Infusion and Injection Therapy

Your products are hot and wet after processes such as hot water sterilisation. Your polypropylene bags or glass bottles can be gently dried by our low temperature system, and cooled subsequently if desired. Our drying or drying-cooling solutions are flexible and may thus be used for any continuous or batch processes – in manual or fully automatic operation. The normal drying temperature is between 40 °C and 75 °C.

Grasses, Herbs and much more

Our gentle low temperature drying method can be much helpful in manufacturing or processing your products. Applications are multifarious and highly specific. Much so are our drying solutions. Learn more about food drying here.

Ampoules and Vials

Our dryers may be used no matter if your products are made from glass, plastic or other materials. Drying is always effected at low temperatures. No matter how many ampoules or vials are placed in whatever receptacle – our solution will always ensure reliable and full drying.

Viscous Materials / Semi-fluids / Semi-solid Pastes

A continuous (belt) drying process is recommended for such drying applications. Our low temperature method is capable of drying these substances gently, at temperatures between 40 °C and 75 °C, to the desired degree of dryness. The use of dry air combined with customised air routeing ensures uniform and exact drying results.

Containers, Baskets and Trays

Nach dem Reinigen, Waschen oder Sterilisieren – immer geht es darum absolut trockene Waren zu generieren, um sie für eine sofortige Weiterverarbeitung vorzubereiten. Für besonders anspruchsvolle Anwendungen, wie es bei Behältnissen oft der Fall ist, kombinieren wir unsere Trocknung mit einer vorgeschalteten druckluftfreien Abblaseinrichtung. Unser Trocknungssystem ist in jeder Hinsicht flexibel und in jede vorhandene oder geplante Prozessart integrierbar.

Items having undergone cleaning, rinsing or sterilising invariably require perfect drying for subsequent processing. For particularly challenging applications, such as where containers are involved, we combine drying with upstream non-compressed air blowing. Our drying system is flexible and may be integrated in any existing or planned process.

Lozenges and Tablets

Drying is also an important step in the production of pastilles and pills, contributing to the quality of your products. On top of the benefits mentioned above, our drying method provides another bonus: Valuable ingredients and important flavours are preserved because drying takes place in a closed circuit. Also, this closed system makes drying independent of the climate and other external impacts.

Blister Packages

Drying drug blisters essentially requires superficial water to be completely removed while retaining the integrity of the contents. Learn more about packaging drying solutions here.

Implants and Biomaterials / Diagnostic and Surgical Instruments

Implants and instruments have special surface finishes applied which require subsequent stain-free, reliable and complete drying. Sadly, hot air blowers are frequently used for this purpose although they fail to produce the desired results. Our low temperature, dry air dryers offer the perfect alternative. Learn more about drying surface finished products here.

The Process

The success of our drying is based on a nifty combination of air conditioning and air routeing. We provide the best dyring results to you by directing extremely dry air exactly to or over the products to be dried.

Tests provide valuable Information and Confidence

Series of tests run in our test center provide valuable information and confidence. We test your product for response to temperature, time, humidity, air speed and airflow rate. We also look at the routeing of the air inside the dryer because this is a critical factor on the way to success. To do all this, we have several multifunctional dryers which our engineer adapts to the specific application. Our service to you includes, of course, an evaluation and interpretation of, and a comprehensive report on the results of these tests.

Sometimes, the parameters for a successful solution are clear at hand after just one series of tests. Every now and then, several runs with varying configurations are required. This is the moment when it takes the knowledge and creativity of our engineer to find a good solution. And we always find one.

We have run thousands of drying tests in our test center in more than 30 years. The experience gathered and the know-how obtained therefrom may not be valued high enough. And it is for your benefit.

Our test center will provide answers to your questions. You tell us the ideal conditions under which your product should get dry. We have a wealth of experience with solvent-based agents and with packaged products. As an outcome of our tests, we will furnish a solution in conformance with hygienic design and GMP/GAMP requirements. The results are very often much better than expected by our customers. We can routinely stun our customers in terms of time & temperature.

You have a new Product Idea?

You are planning to introduce an entirely new product and do not know exactly how to do the drying?

Whatever the challenge to be met we will be glad to deal with it. It is our passion to find the best drying solutions. When running tests, our engineer quickly sees which parameters are best suited to ensure successful drying. If products are particularly demanding there is always an engineering trick to help us arrive at a solution.

You are a Research Enterprise or a University?
