Ammonia refrigeration systems often rely on more than one compressor type to achieve efficient performance across a wide range of operating conditions. Throughout this series, we have looked at reciprocating compressors, which remain the mechanical backbone of many systems, and rotary screw compressors, which dominate large industrial applications. The final piece of the puzzle is the rotary vane compressor, a design that, while less common than the other two, plays an import

Remote meetings have transformed how we do business. They allow us to collaborate across time zones, move quickly, and stay connected despite demanding schedules. At Macha PSM and Samwise, we rely on these tools every day for business development and technical exchanges. But something is getting lost. Recently, our team joined a virtual meeting where only a handful of participants had their cameras on. The energy was low. Engagement felt distant. The conversation, while techn

Population data continues to come up during EPA Risk Management Program inspections and technical discussions, specifically the use of 2010 Decennial Census population data in off-site consequence analyses. The issue is simple: that data is over a decade old. Why this matters Population counts directly drive the number of people potentially impacted in both worst-case and alternative release scenarios. If that input is outdated, the output is also outdated, regardless of how

OSHA, from time to time, issues “interpretations” that explain how the various language in its regulations will be enforced. On June 5, 2015, an OSHA memorandum was issued that addressed several topics regarding RAGAGEP. One of the topics of the memorandum addressed the words “shall” and “should” as used in the RAGAGEP. While these two simple words should be straightforward in interpretation, we shall see that it is not necessarily the case. First, “shall” was discussed as u
