Heraeus (Thermo Fisher) B 6200 Inertgas Drying Ovens

2x Heraeus B 6200 Drying Oven / Heating Oven with Gas Flushing (Complete Set)
The plant has an operational conversion with an external gas control system and internal distribution lances. This enables a controlled flushing (continuous purge) of the interior with inert gas. This drastically reduces the humidity and oxygen content in the process – ideal for oxidation-sensitive semiconductor processes, optics or electronic components.

Working principle of gas flushing:
The devices enable controlled flushing of the interior with an externally supplied gas (e.g. nitrogen, argon or dried compressed air).
The gas is precisely dosed via the external flowmeter (rotameter).
The introduction is via perforated copper distribution lances on the ceiling of the interior.
Important technical note: Due to the design, this is an open, dynamic flushing (continuous purge) to stabilize the interior and not a hermetically sealed, pressure-tight inert gas atmosphere.
