Our way for drying

is special.
More fast. More reliable. More gentle. More safe.

Drying after

Surface finishing, Painting and Cleaning

The HARTER purpose devised Airgenex® drying technology is capable of drying surfaces and solid matter of all kind in a gentle and energy saving way, plus reliably and fast. This so-called heat pump based condensation drying resolves drying problems and optimizes manufacturing processes.

On the following pages, you – no matter if you are a plant operator, construction company or planning office – may find advantages of our drying technology, how it works and where it is applied.

Your Benefits

Very fast

Airgenex® condensation drying saves you 50% of time required by conventional drying methods, such as hot air drying or simple fan-based systems. You will be surprised how much we can reduce your drying time!

Very reliable

The dehumidification process takes place in a system which is closed in terms of thermal energy. Our drying systems are thus completely independent of effects of the climate and the weather. This ensures highest process reliability for you. Plus you are on the safe side if production quantities need to be raised.

Very efficient

The heart of the Airgenex® dryer is a highly efficient heat pump based dehumidification module. Components installed are the best available, some of them purpose built for us, and are made from high grade materials. We combine air dehumidification with sophisticated air routeing such that the dry process air is directed only to where it is supposed to absorb humidity. Also, drying is effected in a closed system with heat recuperation. This makes drying take full effect while being extremely cost effective.

Very gentle

Airgenex® dries products or materials at low temperatures between 20°C and 90°C as required for the specific application. This low temperature drying prevents undesired heating of the materials and products. Stain-free parts and reduced reject quantity means higher productivity for you.


Factors which will optimise the efficiency of the drying process vary for each application. In-barrel drying of bulk material poses challenges much different from those of drying racked products with complex geometries or painted surface.

The most common applications are shown below.

Your application is different?

You will surely understand that, with more than thousand drying systems installed, we cannot possibly list all our potential applications. If your application is not listed above, please do not hesitate to contact us. We will be glad to give you advice without engagement on your part!

The Process

We dry using dry air directed to the right places: A perfect interaction of air conditioning and air routeing provides the best drying result possible.

Pilot Plant Station

Our Pilot Plant Station – One of our special features
Would you like to read in cold print how efficient our drying technology is for your specific application? Our in-house pilot plant station may be used to conduct drying tests with your products. The purpose is to identify and record the relevant parameters for successful drying : temperature, time & humidity, air speed & airflow rate, air routeing. You are, of course, welcome to witness testing and get a personal feel.
On-site testing
Under special circumstances, we can also offer loan units for drying tests at your premises. One of our engineers will instruct you on how to run your own tests.
