New Glarus Brewing Company Case Study on TPO Measurement

This case study details the implementation of the Pentair Haffmans Inpack TPO/CO2 Meter at New Glarus Brewing Company, a craft brewery located in Wisconsin, USA. The brewery aimed to enhance its filling process by accurately measuring Total Package Oxygen (TPO) values. Prior to using the c-TPO, the brewery relied on the air shakeout method, which was insufficient for detecting low oxygen levels. The installation of the c-TPO allowed for immediate feedback on oxygen content, leading to a significant reduction in average TPO from 150 ppb to less than 60 ppb. The c-TPO measures both headspace and dissolved oxygen, providing more accurate results than previous methods. The case study highlights the advantages of the c-TPO in identifying issues during the filling process, particularly during tank changes, and emphasizes its role in maintaining high quality standards at the brewery. The document outlines the technical specifications and operational benefits of the c-TPO system.
