Adhesion water drying is one of the crucial steps after galvanic, chemical, or mechanical cleaning processes. It significantly determines whether components come out of the line spot-free, corrosion-resistant, and ready for assembly. With the heat pump drying systems from HARTER, you achieve exactly that: reproducible, consistent, and energy-efficient results – even with complex component geometries.
The closed, exhaust air-free drying system operates independently of the ambient air and ensures constant process conditions in all seasons.
How HARTER develops individual solutions for industry and electroplating is shown by: This is how solutions for heat pump dryers are created.
The physical principles of the technology are described in: Energy-saving drying with heat pump.

Adhesion water drying – Functionality and advantages of heat pump technology
In adhesion water drying, the water adhering to the surface is gently removed after rinsing or cleaning processes. In contrast to conventional hot air, heat pump drying works in a closed circuit – without exhaust air, controlled, and resource-efficient.
The principle:
- The air is dehumidified, tempered, and guided over the product.
- The water evaporates without residue, without stains or traces of oxidation.
- The heat generated in the process remains completely in the system – without energy loss.
Your Benefits:
- Spot-free, uniform drying even with undercuts
- Process-safe and independent of the ambient air
- Temperature-gentle (30 – 75 °C)
- Up to 70% energy savings compared to hot air systems
- Absolutely exhaust air-free, no odor, no particle entry
Due to the precisely regulated humidity and temperature, even hard-to-reach areas dry reliably – a crucial factor in electroplating, medical technology, and the precision industry.
Drying systems for adhesion water drying
Adhesion water drying – Applications, industries, and system variants
Adhesion water drying is used wherever components must be further processed free of residual moisture after cleaning, rinsing, or passivation. HARTER delivers individual solutions for small workpieces as well as for large-format components or series production.
Typical applications:
- Galvanic surface treatment (zinc, nickel, chrome, copper)
- Metal and plastic components with complex geometries
- Components with blind bores, gaps, or undercuts
- Workpieces after chemical degreasing or passivation
- Medical and precision parts, where cleanliness and appearance are crucial
System solutions:
- Chamber dryers for flexible batch processes
- Tray dryers for sensitive or small components
- Belt and tunnel dryers for automated electroplating lines
- Special systems for bulk goods or component carriers
Before realization, HARTER tests your original parts in its own technical center. There, air flow, temperature, time, and target residual moisture are precisely determined – the basis for a validated, reproducible series system.
Further industrial application fields can be found under Industries.
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.
