Drying after Coating

  • Up to 45% subsidized acquisition costs

  • Save up to 75% on energy costs

  • 100% planning reliability thanks to premium after-sales service

The Airgenex® coating dryers, specially developed by Harter, gently, energy-efficiently, safely, and quickly dry all types of surfaces and solids. These heat pump dryers utilize condensation drying. They resolve drying challenges after coating and optimize manufacturing processes.

Below, you will learn more about the advantages of our coating drying technology, how it works, and where it is applied – regardless of whether you are an end-user, plant manufacturer, or engineering firm.

Your benefits

Airgenex® dries your products or materials at low temperatures between 30 and 75 °C, depending on the application. This low-temperature drying prevents any undesirable heating of the materials and products. Components are free of cracks, craters, and bubbles at the end, as we dry them homogeneously and gently from the inside out. This all translates to higher productivity for you.

Our heat pump technology can be integrated into any type of drying system, ensuring you receive a customized drying solution. We are also flexible with regard to water-based and solvent-based coatings, offering solutions for your specific application.

It is sometimes possible to convert an existing drying process to our system. Please contact us to discuss this.

Because the dehumidification process takes place in an energetically closed system, our drying systems operate completely independently of climate and weather influences. This ensures maximum process reliability for you. Our coating dryers also offer reliability for future capacity expansions.

The core of Airgenex® coating drying is a highly efficient heat pump-based dehumidification technology. It is equipped with the best components, some of which were specially developed for us, and first-class materials. We combine our air dehumidification with sophisticated air guidance, ensuring that the dry process air reaches precisely where it needs to absorb moisture. Furthermore, drying takes place in a closed system with heat recovery. This approach allows our drying technology to achieve its full potential while being extremely economical.

Drying Systems for Coated Surfaces

Our dryers for coating applications are always custom solutions. They are available as batch dryers or continuous systems – all tailored to your product, your process, and your available space.

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.”
