Leakproof dual cavities designed for performing acid evaporations under own atmosphere (class 100 or ISO 5). They can contain one or two hot plates per compartment according to the size. They include air inlets equipped with absolute filters, lockable swivel doors (sealed with flexible membrane and O-ring), a shared extraction pipe, a leakproof electric cable feed to supply power to each hot plate. A liquid column manometer with filter to check for clogging if the equipment is not installed in a white room.
Under the action of the extraction fan, the steam-filled hot air is suctioned out diagonally across the station and the absolute filter and evacuated towards the ventilation ducts. Required extraction 100-150 m3/h.
