Model Zonda -Controlled Atmosphere Reactor

When the door (1) of the controlled atmosphere – cold or preheated - is opened, the parts can be loaded onto the stacking tray (2) which slides out of the unit automatically for easy access. Once closed, the programmed cleaning cycle starts. The process may contain a melting phase to remove most of the polymer or contamination from the delicate parts, in which case the melted material (3) can be removed prior to the start of the real cleaning cycle, or left in the unit to slowly evaporate later in the cycle. The cleaning cycle itself takes typically 1.5 to 3 hours, depending on the parts and the quantity of polymer to be removed. The atmosphere – temperature and oxygen content - in the reactor is permanently controlled to keep temperatures right all the time and to avoid overheating or burning at all times. The reactor is electrically heated (4), and the gases leaving the reactor pass through an ignition and postcombustion chamber (5) to clean the exhaust flow.
