Type 324 - vacuum


The ACI tank sight glass type 324 is a modified version of the Type 321, intended for an extended range of applications for vacuum applications. They are used to observe and illuminate the interior of closed containers (boilers, tanks, silos, etc.).

The PTFE-encased gaskets normally used in Type 321 are no longer safe to use above a temperature of 200°C. In order to eliminate this disadvantage, we use high-quality special gaskets for the Type 324, so that the operating range of the borosilicate glass plates according to DIN 7080 up to 280°C, or even 300°C with a mica disc, can be used completely.

Even at temperatures above the limits of DIN 7080, Type 324 can be used without problems up to 400°C due to high-performance materials such as quartz glass or sapphire glass.

The Type 324 offers you the same advantages as our proven Type 321. Here, too, the glass plate remains optimally protected on the entire circumference and the fitting can easily be installed or replaced like a single component. The fitting is completely assembled at the factory and a vacuum test can be carried out on request so that you can rely 100% on our quality.

As with the Type 321, the Type 324 can also be supplied on request with lighting based on LED or halogen lamps directly from our production.
