Multiple session times available

Schedule

This online course consists of recorded lectures available on demand and live Q&A sessions. Your registration gives you access to course content during the four-day access period. All course instruction will be provided in pre-recorded videos available on demand. The live Q&A sessions are available to you for clarification on topics and answers to questions that you may have regarding the course.

Registrants will receive an email containing instructions on how to access the online course and live Q&A sessions. The email will be distributed at least (2) business days prior to the start of the four-day access period. Instructor-led Q&A sessions are hosted in Microsoft^® Teams^®. Xchanger Suite^® examples are used to complete case study exercises. If a registrant does not have access to HTRI software through a member company, HTRI will provide a temporary license for use during the event. All training materials are based on the current software version.

Description

If you work with plate-and-frame geometries, Xphe^® is the software for you. In this workshop you will discover how to use HTRI’s graphical tool for rating plate-and-frame heat exchanger designs and for conducting comparative studies of plate-and-frame versus shell-and-tube design solutions for specific applications. You will learn how Xphe handles single-phase and two-phase heat transfer and pressure drop for common corrugated plate patterns in a variety of configurations, from single-pass, single-plate arrangements to multipass, mixed plate designs. You will also leave with a better understanding of the analytical methods used in Xphe. Note that crossflow plate-and-block type arrangements are not accommodated in Xphe and are therefore not covered in this workshop.

Key Topics

• Overview of Xphe capabilities and applications (single-/multiple-plate types and passes, non-Newtonian fluid specification, port maldistribution, and more...)
• Process specifications for rating, simulation, and design
• Guidelines for specifying fluid properties
• Geometry input
• Introduction to HTRI analysis methods

Suggested Participants

Process and thermal design engineers that evaluate plate-and-frame heat exchanger performance

HTRI Software

This course will make use of the following HTRI software: Xchanger Suite^® components Xist^® and Xphe^®

Course Credits: 6 hours (PDH/CEU)

Course Fee: US$450

Beyond the Basics: Interpreting Common Xist Warning Messages Webinar (Asia)

March 17, 2026
9:30 PM CDT (UTC -05:00)
Targeted for audience in Europe and Asia

Description

Session targeted for audience in Asia (Date/Time Conversion: March 18, 2026 at 8:00 AM – 9:00 AM India Standard Time, 10:30 AM – 11:30 AM China Standard Time, 11:30 AM – 12:30 PM Japan Standard Time).

This webinar describes the different types of error messages that Xist® can generate. We focus on several important messages that end-users sometimes misunderstand or overlook. These messages include warnings about a low B-stream (MN 1025), fluid property extrapolation (MN 5033), latent heat warnings (MN 5090, 5091, 5051, 5010), and local intube temperature pinch (4128). We describe the origins of these messages, their impact on cases, and potential fixes for the issues they highlight.

Join this free webinar to learn more.

Duration: Approximately 60 minutes

Registration deadline: March 15, 2026 (11:59 PM US Central Time)
