Daniel Szczurko, VP Business Development at BEPeterson states, "The unique feature of this vacuum chamber was the requirement for a quick opening hydraulic closure. The lifting mechanism was designed to lift the 1000 lb. cover to a full 90⁰ open position".

The vessel required a 5 torr or better leak rate. The test procedure isolated the vessel from the vacuum pump with a ball valve with the pump turned off. A gauge was monitored and recorded vacuum for ten minutes. The vacuum loss, based on the vessel size and empty state, after ten minutes was fewer than 2.5%.
Brad Welch, COO of Godfrey & Wing states "the vessel for this 60" system was among the largest we’ve incorporated into a line. We’d not worked with BE Peterson before and were surprised at that fact once we visited and saw their capabilities. Our Engineering teams worked well together to define the project requirements and make the inevitable adjustments required during execution. The system is installed in a large automotive tier one in Mexico and performing to the demanding vacuum levels our process employs."
