To control the operation of the FSM complex, prevent accidents and high-quality production of carbon black, an observation window is provided in the reactor chamber (for all models of the FSM line).
The construction of this node fully complies with the standards of vacuum equipment, which guarantees the tightness of the complex as a whole.
Glass is heat-resistant and fireproof, which allows it to be used in conditions of prolonged synthesis of carbon black, and even in emergency cases of local or complete overheating of the reactor chamber.

The cooling base of the mounting unit provides additional resource for the viewing window, which also eliminates overheating of the inner surface of the glass from the thermal effect of the arc glow in the reactor chamber.

The sight glass is mounted in an ISO-type flange assembly with integrated seals both from the inner plane and from the outside.

ATTENTION!
Quartz glass of viewing windows with chips or cracks are not suitable for installation on equipment. In case of damage to this element, its replacement is required to eliminate vacuum or gas leaks.
