votschtechnik Heating and Drying Ovens for Clean Rooms, VTF
Designed for Clean Environments
The VTF series from vötschtechnik (Weiss Technik) is purpose-built for heating and drying in clean room settings. These ovens ensure minimal contamination, precise thermal control, and full compatibility with ISO 4 to ISO 7 clean room classes.
Key features include:
1. HEPA filtration in both fresh and circulating air paths to maintain clean room purity.
2. Uniform spatial temperature distribution via low-turbulence flow design
3. Rapid recovery after door openings for shorter cycles.
4. Compact footprint, allowing units to be placed side by side.
5. Option for silicone-free versions (with Viton seal) up to 450 °C.
6. Available in versions for combustible or inert gas processes, or with explosion protection.
7. Integration into automated production lines and pass-throug models.
8. WebSeason® control interface for programming, monitoring, and remote access. 
Verified Technical Highlights
From the publicly available information:
• The VTF ovens support clean room requirements ISO 4 to ISO 7 per DIN EN ISO 14644-1.
• The maximum continuous process temperature is 350 °C in standard versions.
• A silicone-free variant (with Viton sealing) is available, enabling operations up to 450 °C in certain configurations.
Typical Use Cases
The VTF series is ideal for processes that demand both thermal treatment and strict cleanliness, such as:
1. Semiconductor, electronics, and microfabrication
2. Medical device and pharmaceutical component drying
3. Cleanroom assembly areas requiring post-process heating
4. High-purity drying, curing, or conditioning of parts
