Introducing the TU-620 Airflow, Motor, and Electric Heat Training Unit
Teaching airflow dynamics in HVAC classrooms has always been a challenge for instructors. Traditional lecture-based methods often fall short in helping students grasp how motors behave under varying static pressure conditions, or how restrictions on the return or supply side impact system efficiency. The TU-620 Airflow, Motor, and Electric Heat Training Unit from iConnect Training is designed to eliminate these hurdles and empower instructors with a hands-on solution that brings airflow and motor diagnostics to life.
The Challenge: Teaching Airflow Without Real-World Scenarios
In a typical HVAC classroom, instructors are often limited to diagrams or theoretical examples to explain complex concepts like static pressure, airflow resistance, and motor performance. But airflow is invisible—and that makes it hard to teach. Students may memorize terms like “CFM” or “pressure drop,” but without tactile experience, the concepts don’t always stick.
Many instructors also struggle to demonstrate how different motors—such as PSC, ECM Constant Torque, and ECM Constant Airflow—respond under identical conditions. Without the proper equipment, it’s nearly impossible to simulate the impact of duct restrictions, filter changes, or electrical faults in a safe, controlled, and measurable environment.
The Solution: TU-620 Airflow, Motor, and Electric Heat Training Unit
The TU-620 gives instructors everything they need to transform how airflow is taught in the classroom. With three interchangeable motors and integrated measurement tools, instructors can demonstrate key HVAC performance metrics in real time—including static pressure, airflow (CFM), amperage, wattage, RPM, resistance, voltage, continuity, and more.
New capabilities now include built-in electric heat strips and blower performance charts for all motor types. This allows instructors to teach students how to calculate airflow using the temperature rise method with the sensible heat formula—a proven, field-tested method still widely used by technicians today. It also opens the door for practical lessons in electric heat operation, expanding the unit’s instructional versatility.
One of the most exciting upgrades is the ability to easily measure pressure drop across various filter types. This is a game-changer for teaching how restrictive filters can impact system performance and energy efficiency. Students can test and compare real-world pressure differences between standard, pleated, and high-efficiency filters—something rarely possible in a traditional lab setting.
This unit allows students to see how airflow responds to various restrictions and motor types. For example, in Lab 3, they can measure how return-side restrictions reduce CFM and increase energy usage. In Lab 10, they’ll learn how to properly diagnose whether an ECM failure is due to the motor itself or the control module. These real-world diagnostics are what make the TU-620 an essential piece of any HVAC training program.
Real-Time Data. Real-World Relevance.
The TU-620 provides the kind of real-time feedback and control that instructors need to turn abstract concepts into clear, measurable outcomes. With built-in tools like manometers, multimeters, and psychrometers, students can collect and analyze live data—just like they would in the field. This not only prepares them for certification exams but gives them confidence to troubleshoot airflow and motor issues on actual job sites.
Built for the Modern HVAC Classroom
The unit’s compact 70″ x 30″ footprint makes it ideal for classrooms with limited space, and the included eLearning curriculum enables instructors to easily align lab work with theoretical instruction. With 17 suggested lab modules covering airflow characteristics, electrical diagnostics, and energy efficiency, the TU-620 seamlessly fits into a semester-long HVAC course or targeted workshop series.
For instructors looking to level up their HVAC curriculum, the TU-620 Airflow, Motor, and Electric Heat Training Unit is more than just a trainer—it’s a full educational platform. It solves the common pain points of teaching airflow, offers flexible learning pathways, and gives students the practical skills they need to succeed in the field.
