Understanding Aftertreatment Temperature Diagnostics

Get an in-depth view of regeneration system components and operation. Additionally, you’ll learn the importance of running a regeneration for diagnostic purposes, and the powerful insight that it gives you for diagnosing failed components without the need for a fault code.

Header Rebuilding by Hand

Also known as a one-tank rod out, this process could be performed if the radiator is running hot and you have to rod the tubes out to restore heat transfer, if a seam is leaking where the tank is soldered into the header, or you have a tube to header leak. The Affton Radiator team will deconstruct this process and explain the benefits of using this method.

Radiator Header Rebuilding by Dipping

For radiator repair facilities that do not manufacture new radiator cores, this process can be used to help speed up the downtime for customers’ machines or equipment or reduce cost to the overall life of the radiator assembly. This is an art form process that is performed to completely rebuild the original conventional radiator core that comes through a radiator repair facility. The team at Affton Radiator (Fenton, Missouri) explain the process step-by-step.

Top Questions about Tube & Shell Heat Exchangers

How can you determine if a tube and shell is worth repairing or not? Why are sacrificial anodes important? How do you determine baffle spacing? With more than 25 years of experience, Radiator Service Co.’s David Bienvenu breaks down the most frequently asked questions when it comes to tube and shell heat exchanger service, repair and replacement.

What is Selective Catalyst Reduction (SCR)?

Get an in-depth view of the SCR system components, operation and diagnostics. At the end of this presentation, you’ll be armed with a systematic approach to help find the root cause of an SCR efficiency below threshold fault by understanding how the system operates.

Intro & Service Considerations for PHE, Box Coolers, Fined & Tube Coolers, Double Tube Heat Exchangers (Parts 1-4)

This presentation breaks down the basics of Plate Heat Exchangers including the different types of PHE, and service techniques. It also includes an introduction to box coolers, finned tube oil coolers, and fin tube technology.

Technology & Opportunities in Coils

Learn more about the markets, applications, and technologies for coil products. Raphael Taveras of Industria Core covers coil applications for deep freezers, refrigeration and air handling units. Technologies include direct expansion coils, chiller water/ steam coils, micro-channel coils. Session also goes into special coatings as  well as measurement and information requirements. 

How Does Your Fin Shape Up?

Bob Carlo from Voss Mfg. Co. addresses the critical role fins play in the performance and endurance of the plate heat exchanger. He provides general information about the various n types, applications, shapes, materials, stiffeners, dimples, louvers, and other elements of construction and design. Learn why specific fin types are used in heat exchange applications for products such as oil coolers, charge-air-coolers, bar and plate heat exchange and common radiators.

What Does Durability Testing Tell the Radiator Shop?

The scope of this technical session is to show the radiator shop technician how the results from durability testing – pressure cycle, thermal cycle & vibration – can help them to better identify the root cause of a customer’s failed radiator or CAC. Just replacing a failed unit with a new one will certainly ‘fix’ the immediate problem. But what if the failure was a result of vibration inputs caused from a worn out isolator? By looking at what elements fail in a bench test, it can help guide the technician in identifying the ‘real’ problem and not only sell a new heat exchanger but also allow them the opportunity to fix and bill for additional work.

Wind Tunnel Testing & How Its Related Design Information Impacts You

Test data and its uses do have practical application for service. Joseph Yeremian, President of Thermodyne Engineering Ltd. covers how test data relates to the service world. Learn more about how test data relates to the service world. You'll also see how data is used for sizing and predicting the performance of aftermarket radiators and in general heat exchangers such as oil cooler and charge air coolers.
