Conax designs a multi-hole compression seal fitting/flange for easy replacement and reduced production cost.
Industry: Photovoltaic
Challenge: A customer needed to introduce thermocouple wires through high vacuum boundary in a PV thin film coating application. They also wanted to reduce electrical noise in wiring on the outside of the process chamber.
Solution: Conax used a multi-hole compression seal fitting/flange assembly to seal on the wires, then to the customer’s process chamber. A shield was also added over the bundle of wires that travel from the fitting to a termination box. Inside the termination box, a drain wire was attached to the shielding to allow for proper grounding.
Impact: This customized solution allows for rebuilding of the fitting with new wires as the wires eventually become damaged in use, saving expenses on future needs. This process also served to reduce external wiring noise.
