Process-reliable drying in carrier operation

HARTER rack dryers dry coated or cleaned parts within the cycle time, spot-free and gently on the material. Airgenex® with heat pump operates in a closed system and directs the dry process air specifically over complex geometries. Systems are adapted to your product window and space conditions – including efficient air guidance, automatic lid system and precise control of air volumes.

Your benefits

Each rack dryer is designed for the dimensions, loading and material mix of your carriers. Airflow, nozzle arrangement and chamber geometry are adapted to your process chain – for short cycle times and stable quality.

Specifically guided, dry process air reaches undercuts, blind holes and tightly packed areas. This avoids residual moisture, staining and rework – even with high occupancy and varying part sizes.

Heat pump-based condensation drying in a closed circuit with heat recovery significantly reduces energy consumption. Regardless of the room climate, temperature and humidity remain constant – for reproducible results.

The lid only opens for loading and unloading the carrier. Heat and dry air remain in the system, the temperature drop in the dryer is reduced – this increases efficiency and shortens the heating times between batches.

Efficient EC fans can be controlled via a 0–10 V signal. Optionally, a frequency converter provides product-specific volume flows and pressure levels – ideal for a wide range of parts and changing requirements.

A compressed air-free blow-off technology removes standing drops before drying starts. This reduces drying times, prevents stains and relieves the actual drying process.

Depending on the medium and temperature, PPs or stainless steel versions are used. Corrosion resistance, cleanability and durability are tailored to your surface and cleaning processes.

In test series, we determine temperature, humidity, time, air velocity and volume flow for your parts. The recipes derived from this ensure series maturity, process stability and quality from the outset.

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.”
