NEEDED MATH PROJECT
Exergy, LLC Site Visit Exergy has been in business for 43 years and produces a range of heat exchangers from small, compact to very large that are used in the following industries: Pharma/Bio, Chemical, SemiConductor, Alternative Energy, and Food & Beverage. Chris Dufrenoy (Director of Operations) worked closely with Jordan Finkelstein (President) to coordinate our virtual visit. Chris led us on a tour of a variety of work centers; Shipping & Receiving, Finishing, Quality Control, and Assembly. We came away with a solid understanding of the workflow. Following the tour of work
centers, we spoke to five technicians about the work that they do and the math that they use. We found that they use more math than they thought they used, ranging from conversions (e.g., from metric to English units or from decimals to fractions) to reading and understanding graphs and diagrams. Technicians also need to be familiar with a variety of tools for measuring and calculation. We are grateful to Exergy for arranging this site visit, which added to our knowledge of the math technicians need to know on their jobs.
To Manufacturers: Your help is vital in helping us to grow our Needed Math knowledge base. You can help by inviting us to speak virtually with a small group of your company’s technicians and their supervisors via Zoom to find out the math needed for technicians to be successful at their jobs. If you are interested and we hope you are, please contact Dr. Michael Hacker (Michael.Hacker@hofstra.edu)
