A leading supplier of precious metal and base metal mint products has chosen the EC913 process oxygen analyzer from Systech Illinois to monitor the oxygen in its furnace atmosphere.

Based in Idaho, Sunshine Minting Inc. (SMI) is a leading supplier of precious metal and base metal mint products. Customers include governments, financial institutions and major corporations around the world.

With such high standards to maintain, SMI has chosen the EC913 process oxygen analyzer from Systech Illinois to monitor the oxygen in the heat treating/annealing furnace atmosphere.

Concentrations as low as 1,000 ppm can cause oxidation of certain metals at high temperature, which can lead to cosmetic flaws, pitting or a dull surface finish, which is unacceptable as a finished product. After installing the EC913 however, operators no longer have to guess the oxygen concentration and waste expensive nitrogen to displace it.

The EC913 monitors any oxygen (air) intrusion and any leaks can be blocked or plugged. This controlled process limits waste and increases efficiency of the minting operation, Systech Illinois claims, ensuring it is perfectly suited to the operations of SMI.

Sean Moffat of SMI, said, “The Systech Illinois O2 sensor has worked great and found two separate points of O2 intrusion in the Hayes furnace, as well as proving to the annealing supervisors and operators that certain procedures were introducing O2 into all the furnaces. Installing the EC913 has resulted in savings.”
