In electroplating, drying is the final and crucial step:
Only when components are completely dry after rinsing, passivating, or coating will the surface remain flawless and corrosion-resistant.
An electroplating dryer from HARTER ensures uniform, spot-free, and energy-efficient drying – regardless of ambient climate, season, or humidity. With its innovative heat pump technology, HARTER operates exhaust-free, hygienically, and reproducibly.
How the systems are individually adapted to your production processes is shown in: How Solutions for Heat Pump Dryers are Developed.
The physical principles of the process are described in: Energy-Saving Drying with Heat Pump.

Electroplating Dryers – Operating Principle and Advantages of Heat Pump Technology
The HARTER electroplating dryer operates in a closed air circuit. The process air is dehumidified, heated, and recirculated over the product.
This keeps the air consistently dry and warm – ideal for components with bores, undercuts, or hard-to-reach areas.
Your Advantages at a Glance:
- Spot-free, uniform drying
- Low temperatures (30–75 °C) – ideal for sensitive surfaces
- No exhaust air loss, no energy waste
- Up to 70% energy savings compared to hot air systems
- Stable process conditions – independent of ambient air
Thanks to the exhaust-free circuit, moisture evaporates completely and in a controlled manner. This prevents water spots, oxidation, or stress cracks – a crucial advantage for high-quality galvanic coatings.
How this technology can be scaled is shown in: Expanding Capacities with Heat Pump Dryers.

Electroplating Dryers – Applications, System Variants, and Integration
The HARTER dryers for electroplating are used in a wide range of industries – from automotive and electronics to medical technology.
All systems are modular in design and can be precisely integrated into existing lines.
Typical Applications:
- Drying after electroplating, passivating, or rinsing
- Components with complex geometries (e.g., blind holes)
- Zinc, nickel, chrome, or copper coatings
- Plastic or hybrid parts with galvanic surfaces
System Types:
- Chamber dryers for batch operation
- Belt or tunnel dryers for continuous lines
- Tray dryers for sensitive parts or bulk goods
- Special systems for specific carrier systems or rack goods
Each system is tested and validated in our in-house technical center. HARTER determines the optimal parameters for your original parts – air flow, temperature, humidity, and time. The result: a stable, reproducible process with documented quality values.
An overview of further application areas is provided in: Industries.

Electroplating Dryers – Energy Efficiency, Sustainability, and Economic Viability
In addition to process quality, energy efficiency plays a central role. HARTER’s heat pump technology drastically reduces energy consumption and lowers operating costs – while maintaining consistently high surface quality.
Sustainable advantages:
- Up to 70% energy savings through heat recovery
- No exhaust air emissions → no filter maintenance
- Low CO₂ emissions due to closed circuit
- Low-maintenance components and high system availability
- Eligible technology according to energy efficiency directives
Through precise control of temperature and humidity, the process remains reproducible – regardless of production conditions or weather.
The systems can be equipped with digital monitoring and automatic data logging to support quality assurance documentation or audit records.
