Product description

Our air-cooled furnace camera is able to observe processes in hot environments. The excellent insulation of the probe with high specification materials protects the optical parts against heat. Continuous airflow ensures that no dust can enter the system and damage the exit window. Depending on the design, the front of the system can withstand temperatures of up to 1.300° C.

Principle of operation

The system requires only a small volume of purge air, provided by an air-supply cabinet.  A backup compressed air cooling system takes over in case the air supply is interrupted. In addition, the cooling air protects the systems from contamination from the furnace.
