vötschtechnik Dryers and Ovens, in which flammable substances are released, HeatEvent F
Safe Thermal Processing Where Solvents Are Released
When your process involves evaporating solvents or flammable vapors (e.g. coatings, resins, wet coatings), safety is critical. The HeatEvent F series from vötschtechnik (Weiss Technik) enables controlled, safe drying and heat treatment by adhering to EN 1539 standards.
These units are engineered to prevent explosive mixtures from forming in the chamber by constantly exhausting vapor-laden air and replacing it with fresh air, while monitoring critical parameters to ensure process integrity. 
Key Safety & Performance Features
1. EN 1539 compliance — Designed to control solvent release in ovens and dryers here flammable substances evolve.
2. Constant exhaust & fresh air exchange — Ensures that vapor concentrations remain below critical levels.
3. Sealed, welded interior construction — Prevents solvent leakage into insulation or mechanical elements.
4. Dynamic exhaust rate control — After heavy evaporation phases, airflow may be reduced (e.g. 25%) to save energy while maintaining safety.
5. Safety class control & monitoring — Airflows (recirculating & exhaust), max/min temps, and limiters are monitored by safety-rated parts (PL d performance level).
6. Standard intelligent control & connectivity — Comes with S!MPAC® control and WebSeason® interface for program creation, logging, and remote monitoring (supports AMS 2750E, CQI-9).
7. Flexible upgrades — Optional features include additional sensors, access ports, more aggressive exhaust, cooling or inert gas adaptation, etc.
Typical Applications
HeatEvent F is ideal when solvent vapors or flammable gases may evolve during thermal processing, such as:
• Drying of coated or painted components
• Curing impregnated composites or laminates
• Evaporation of solvents in chemical processing
• Thermal ageing or conditioning of materials with volatile species
Whenever safety is mandated, HeatEvent F ensures controlled vapor handling and minimizes the risk of explosion.
