Drying Oven for Electroplating

In electroplating, drying directly determines the quality of coated parts. Water or chemical residues quickly lead to spots, corrosion, or adhesion problems. With a HARTER drying oven, you ensure brilliant results – energy-efficient, clean, and reproducible. HARTER heat pump technology ensures controlled conditions, constant temperatures, and exhaust-free processes.

After galvanic coatings – such as nickel, zinc, chrome, or anodizing – components must be reliably dried. The rule is: no drops, no residues, no surface alteration. The HARTER drying oven operates with dehumidified, tempered air that circulates in a closed loop.

The process air is dried via a heat pump and then brought back to the optimal temperature.
This creates a uniform, gentle drying process that protects even sensitive surfaces – without spots or edge marks.

Advantages of the Technology:

• no exhaust air, no external air influences
• stable, reproducible process conditions
• low temperatures between 30 °C and 75 °C
• up to 70% less energy consumption than hot air systems
• short drying times with maximum quality

HARTER systems are designed for a wide range of production environments – from small batches to fully automated lines.
The systems can be flexibly adapted to workpiece size, geometry, and throughput.

Typical applications:

• Drying of galvanized or anodized metal parts
• Surfaces with high optical requirements (e.g., chrome, brass, die-cast zinc)
• Plastic coatings or hybrid components
• Cleaning and dehumidification after chemical pre-treatment

Designs and Options:

• Batch ovens (chamber or tray dryers): ideal for varying workpieces or small series
• Continuous and tunnel dryers: for automated electroplating lines with constant throughput
• Special solutions: Integration into existing systems, special air guidance systems, stainless steel design for cleanroom requirements

Each system is individually designed – from air guidance and air volume to temperature distribution.

The result: a reproducible, validated process without spot formation or distortion.

In its in-house technical center, HARTER tests your original parts under realistic conditions. Parameters such as air velocity, temperature, and humidity are precisely set – forming the basis for precise series design.

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.

Heat pump drying is not only efficient but also sustainable. Thanks to the closed air circuit, there is no need for fresh or exhaust air systems. Waste heat is fully recovered – significantly reducing energy consumption and CO₂ emissions.

Your advantages at a glance:

• stable coating quality through controlled drying
• no spot formation, no water stains or tarnishing
• Energy savings of up to 70%
• hygienic, exhaust-free system
• durable, low-maintenance technology

Furthermore, HARTER enables the integration of modern energy and environmental management systems, such as ISO 50001. Many systems are eligible for funding as they meet high efficiency standards. An overview of further application areas can be found under Industries.
