Process-reliable drying in continuous operation

HARTER continuous dryers dry products continuously or in cycles on conveying systems – reproducibly, spot-free, and gentle on materials. Speed, temperature, and airflow are adjusted specifically for the product. This allows you to seamlessly integrate drying into automated lines and achieve high throughputs with low energy consumption thanks to Airgenex®.

Your benefits

The continuous dryer operates continuously or in cycles. Conveyor speed and dwell time are precisely matched to the product, moisture content, and target residual moisture – ensuring stable quality with high throughput.

Precise airflow guidance directs the dry process air to where moisture escapes – across layers, baskets, or trays. This ensures homogeneous results without over-drying or under-drying.

Drying at moderate temperatures protects sensitive materials, surfaces, and packaging. Spot formation and thermal damage are avoided, and reject rates decrease.

Whether baskets, tray trolleys, or pallets: The continuous dryer adapts to your handling requirements. Standardized dimensions (e.g., Euro pallets) or individual formats can be accommodated equally.

The length, number of zones, and cross-section of the tunnel are adapted to the production volume and component geometry. This ensures the system remains future-proof and can be expanded if required.

The Airgenex® technology operates in a closed loop with a heat pump and heat recovery. This significantly reduces energy consumption and decouples drying from the room climate.

If required, a cooling stage can be integrated – ideal for processes that require defined component temperatures after drying, without additional equipment or footprint.

In drying tests, we determine temperature, humidity, time, air speed, and volume flow for your products. The parameters derived from these tests ensure reproducible results in series production.

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.”
