Industrial Drying Oven Remove Moisture Before Coating
A critical step between pretreatment and powder coating. KETU drying ovens remove surface water and moisture to prevent coating defects like pinholes, bubbles and poor adhesion.
- Prevent coating defects (pinholes, bubbles)
- Fast moisture removal (80-120°C)
- Tùy chọn sưởi bằng khí gas, dầu diesel hoặc điện
- Integrated with pretreatment line
Operating Range

What Is a Drying Oven and Why Do You Need It?
A drying oven is a heated chamber installed immediately after the pretreatment line. After parts go through degreasing, rinsing and conversion coating, water droplets remain in recesses, joints and complex geometries. If you powder coat wet parts, you will see coating defects.
The drying oven solves this problem by:
- Heating parts to 80-120°C to evaporate surface water quickly
- Creating controlled airflow to carry moisture away from the chamber
- Ensuring parts enter the coating booth completely dry
- Preventing pinholes, bubbles and adhesion failures in the final coating
⚠️ What happens without a drying oven?
Water trapped in recesses will turn to steam when the part enters the curing oven, causing pinholes, bubbles and poor adhesion. Many coating failures can be traced back to insufficient drying.

Drying Oven vs Curing Oven: What's the Difference?
Many buyers ask if they can combine both functions. Here's a clear comparison to help you decide.

|---|---|---|
| Mục đích | Remove water after pretreatment | Cure powder coating (cross-link) |
| Nhiệt độ | cURL Too many subrequests by single Worker invocation. To configure this limit, refer to https://developers.cloudflare.com/workers/wrangler/configuration/#limits | 180–220°C |
| Position in line | After pretreatment, before coating booth | After coating booth, final step |
| Thời gian lưu | 5–15 phút | 10–30 minutes (depends on powder) |
| Parts condition | Wet (after rinsing) | Dry with powder coating |
| Air quality requirement | Standard (moisture exhaust needed) | Clean (no contamination on coating) |
| Can they be combined? | ❌ Not recommended. Different temperatures, positions and cleanliness requirements mean separate ovens give better results. | |
💡 Can you skip the drying oven?
If your parts are very simple with no recesses (like flat sheets), you might use forced air blow-off instead of an oven. But for most real-world parts—with holes, joints and complex geometry—a drying oven is the only reliable way to prevent coating defects.
Trying to save money by skipping the drying oven usually leads to high defect rates and rework costs that far exceed the oven investment.
