Xace Workshop

Course Fee: US$450

Do you design only air-cooled heat exchangers? Evaluate their performance? Then this workshop is for you. Unlike the Xchanger Suite workshops, this course focuses only on air-cooler geometry. Learn how to use Xace effectively to rate and design air-cooled heat exchangers, economizers, and air preheaters. All example problems and practice exercises relate to geometries handled only by Xace.

Key Topics

  • Overview of Xace capabilities and applications
  • Geometry inputs for air coolers and economizers
  • Process specifications for rating, simulation, and design
  • Guidelines for specifying fluid properties
  • Introduction to HTRI analysis methods

Suggested Participants

Designers of air-cooled heat exchangers and process engineers who evaluate their performance

Upcoming Instructors

  • Salem Bouhairie


  • Senior Project Engineer, Research, earned his BEng, MEng, and PhD in Civil Engineering from McGill University, in Montreal, Quebec, Canada. While pursuing his graduate studies, he taught Water Resources and Hydraulic Engineering as an Adjunct Professor; Bouhairie also worked as a Laboratory Experimenter in open-channel hydraulics. Following his graduation, he became a Research Assistant at the university, gaining additional expertise with CFD in modeling fluid flows. He worked at Northwest Hydraulic Consultants, in Edmonton, Alberta, Canada, where he conducted physical hydraulic modeling investigations and river hydrology assessments. This experience gave him a broad-based knowledge of heat and mass transfer, thermal- hydraulic design, and computational methods. Bouhairie has delivered presentations on his work in Canada, the United States, England, and Brazil; his work has been published in the Journal of Fluid Mechanics and the Journal of Hydro-environment Research.


  • Andy Mountford


  • Senior Consulting Engineer, Technical Services and Sales, provides technical support and training for HTRI. He earned a BSc and MSc in Chemistry and a PhD in Organometallic and Materials Chemistry from the University of East Anglia, Norwich, UK. During his tenure there, he conducted research at Wolfson Laboratory for Materials and Catalysis. He previously held the position of Thermal Design Supervisor at Tecnicas Reunidas in Madrid, Spain, gaining valuable experience using HTRI methods and software. Mountford oversaw the development of several high-profile PWR and BWR nuclear plant projects, as well as gained valuable experience in the thermohydraulic design of heat transfer equipment for the petrochemical and nitric acid/nitrates industries. His experience in using HTRI Xchanger Suite makes him uniquely qualified to bring an end-user’s perspective to the HTRI training program and to share techniques for effectively working with the software.


  • S. Greg Starks


  • Director of Sales, Americas, graduated with a BS in Mechanical Engineering from Texas A&M University, College Station, Texas, USA. While working at the Shuttle Support Thermal Control Systems Analysis Group of Rockwell International, Houston, Texas, he performed thermal analyses for the space shuttle and developed geometry models for the shuttle/space station. From 1994 – 1999, Starks was employed at HTRI, developing calculation engines for our software as well as a quality control database to track program changes. He then moved to Austin, Texas, to work as the Software Engineering Manager for Tanisys Technology, Inc., a supplier of automated test equipment for semiconductor memory technologies. When he rejoined HTRI, Starks was responsible for enhancements to the Xist calculation engine. He now leads sales efforts in the United States and Canada and assists with HTRI’s training initiatives.


  • Hans Zettler


  • Vice President, Sales, EMEA, joined HTRI while completing his PhD in Chemical Engineering at the University of Surrey, Guildford, UK. His doctoral work focused on fouling and design of compact heat exchangers. He also possesses a mechanical engineering degree (Dipl.-Ing.) from the Technical University Karlsruhe, Germany. Zettler completed multiple internships in industry throughout Europe while pursuing his education. Zettler is responsible for Sales in Europe, the Middle East, and Africa. He is a member of the German Engineering Society (VDI), a member of the VDI-GVC Working Party on Heat and Mass Transfer, an associate member of the Institution of Chemical Engineers (IChemE), and a committee member of the Heat Transfer Society, United Kingdom.
