Your benefits

Thanks to this targeted control, we achieve fast, uniform and gentle drying – regardless of material, shape or geometry. At the same time, we minimize energy consumption through the use of highly efficient heat pump technology. At the heart of the system is a powerful heat pump, combined with precise air guidance. The process air is used specifically where moisture is to be removed without wasting energy. Thanks to the closed system with integrated heat recovery, our Airgenex® heat pump dryers operate with particular energy efficiency, economically and with process reliability. Learn here in brief how our energy-efficient drying technology with air dehumidification in a closed system works – for maximum efficiency and highest process reliability.

For an optimal drying result, we rely on an intelligent interaction of dry air, precise air guidance and energy-efficient air treatment. In other words, our Airgenex® dryers direct the dry process air exactly where it is needed – directly to the moist surfaces or components.

The innovative Airgenex® drying technology from Harter sets new standards in industrial drying. With its unique combination of process reliability, speed, material protection and energy efficiency, it is ideal for demanding applications in production and after cleaning.

Thanks to the energetically closed system, the Airgenex® drying system works independently of climate and environmental influences. This ensures maximum process stability and consistently reliable results – even with capacity expansions.

Drying takes place at low temperatures from 30 °C to 75 °C, depending on the application. The low-temperature drying prevents material stress, protects surfaces and, as a result, ensures stain-free, high-quality results – with reduced waste at the same time.

Compared to conventional methods such as hot air or fan drying, Airgenex® condensation drying enables a drying time reduction of up to 50 %. This means that you can significantly increase your productivity and shorten your processes considerably. Also for drying after cleaning.

Drying systems for surfaces

Whether bulk material directly in the drum, rack goods with complex geometry or continuously conveyed components – each application places its own demands on the drying technology. In other words, depending on the drying process and material type, different factors are decisive for an effective and process-reliable drying process.

With the Airgenex® technology, we offer you customized solutions for a variety of industrial drying applications. Our drying systems are flexibly adaptable, highly efficient and suitable for a wide range of industries.

The Process

We dry with dry air and deliver it to the right places: A perfect interplay of air preparation and air guidance provides you with the best possible drying result.

Interface: Airgenex® Dehumidification Technology / Dryer – Moist air is extracted from the drying chamber and supplied to the dehumidification unit.

The pre-cooler pre-cools the air in a first stage. This significantly reduces the compressor’s energy consumption.

Moisture condenses on the fins of the air cooler and drains out of the drying system via the drip tray and condensate drain.

The cooled, dehumidified air is warmed up without additional energy by means of a pre-heater.
The air heater warms the air to the required process temperature.

The process air fan ensures the necessary air exchange between the Airgenex® dehumidification technology and the drying chamber.

Now, the dry, unsaturated air is guided into the drying chamber, where it absorbs the product’s moisture. Thus, the cycle is closed.

Efficiency that pays off.

Our HARTER drying systems save up to 75% CO₂ and are up to 45% governmentally funded.

What Our Customers Say

Not convinced yet? Our customers are thrilled!

“Sometimes it’s better to say nothing and let your customers speak for themselves.”
– Regina Mader, Managing Director

“For several decades, we have been using a Harter sludge dryer in our contract electroplating facility and are very satisfied with it. The technology and service are reliable and have helped us save a significant amount of money on disposal.”

Daniel Hutter
Verzinkerei Kriessern AG

“BK Giulini GmbH has been successfully collaborating with Harter GmbH for approximately 20 years. We are very satisfied with both the dryer technology and the reliability of the entire system. Based on these positive experiences and the excellent service, we invested in another drying system of this type in 2023.”

Dimitri Baumbach
ICL Ladenburg / BK Giulini GmbH (ICL Group)

“In our waste incineration plant, we have saved a significant amount of money by drying our heavy metal-containing hydroxide sludge. The plant technology is sustainable and maintenance-friendly. In retrospect, the investment was a very good decision.”
