Heating and Drying Ovens for Clean Rooms, VTF The VTF heating and drying oven for clean rooms is characterised by the low-turbulence flow with particularly uniform temperature distribution, required for optimal and repeatable production results. High efficiency particulate air filters (HEPA) in the fresh and circulating air channel ensures IS0 5 clean room class as per DIN EN ISO 14644-1 in the treatment space. Optimal production results due to high purity, corresponding ISO 5 clean room class as per DIN EN ISO 14644-1 throughout the whole programme cycle. High permanent process temperature of up to 350 °C Constant uniform spacial temperature distribution Short process cycles thanks to quick recovery times Incorporation into automated production lines, pass through model and combination with explosion protection
