vötschtechnik ATEX-conform Explosion-Proof Drying Oven, VFT

Safe Drying with Fresh Air Principle

When solvent vapours or flammable gases may be present, drying must be handled with strict safety. The VFT series from vötschtechnik (Weiss Technik) uses a fresh air only design to ensure explosive atmospheres never reach ignition sources.

This ATEX-certified cabinet is TÜV type-examined (TÜV 16 ATEX 7810 X), so it can be commissioned without separate local approval in many jurisdictions.

Its design supports high solvent volumes, while maintaining uniform temperature control and real-time safety monitoring. Shape

Key Features & Advantages

1. Explosion-safe fresh air supply: Only fresh air enters the chamber; no recirculation ensures that no explosive mixture can mix near heating elements.

2. Type-examination & ATEX compliance: Certified per Directive 2014/34/EU, category II 2G (Zone 1) inside the cabinet; outer housing is category 3G (Zone 2) capable.

3. Support for T1–T4 classes & II A / II B groups: Compatible with many common solvent classifications.

4. High fresh air flow (≈ 2 m³/min): Enables safe processing of large solvent loads without accumulation of flammable vapours.

5. Reliable temperature control: PID controller (e.g. JUMO diraTron 104) with self-optimization and stored program capability.

6. Safety monitoring & emergency purging: Volume flow monitors, overpressure control in control cabinet, and automatic emergency flushing under fault or power failure.

7. Compact footprint: Designed to be used in labs or production areas without requiring excessive space.

Additional public specs / features:

• Small external dimensions (approx. 820 × 1,630 × 1,105 mm) for VFT 60/90 variant

• The oven is electrically heated, employing the fresh air principle and designed for lab or production use
