THERMOPAK® EXTERNAL CATHODE BAR SEALS

Primary Aluminum smelters have long faced the problem of how to economically provide a hermetic seal for the life of the reduction cell. Mid-Mountain’s patented THERMOPAK^® External Cathode Bar Seals penetrate the sidewall of the reduction cell, providing additional thermal insulation at each of the cathode bar penetrations, as well as an excellent seal for the life of the pot. In addition to providing an excellent seal for the full-service life of the pot, these boots have the added advantage of providing additional thermal insulation at each of the cathode bar penetrations.

THERMOPAK^® External Cathode Bar Seal Boots are a four-part composite design that works in tandem to protect reduction cell seals from multiple stresses and are the first-ever external seals that have been designed to protect against multiple points of attack. All other sealing methods are typically destroyed by abrasion, heat, chemical attack, blind installation failures, expansion and contraction issues, and leaking cells. The design of the seals ensures good performance throughout the working life cycle of the reduction cell and does not need steel backup plates or welding, making them very quick to install.
