“With R-TRADE Online Learning, we’re giving technicians affordable, on-demand access to education that fits their schedules, allowing them to deepen their knowledge and stay current without disrupting their work,” said Danielle Wright, NASRC executive director. 

Taught by NASRC Training Director Rusty Walker, the first course, “CO2 Basics: Transcritical Booster Systems,” lays the foundation for technicians new to CO2 (R-744) and refreshes existing knowledge for experienced professionals. The course’s eight modules cover topics such as CO2 system architectures and terminology, transcritical booster system operations, hands-on procedures and best practices. Students reinforce key concepts through quizzes to earn a certificate of completion. 

Enrollment is $150 for individuals, with group rates available for companies. Small businesses and NASRC Member organizations receive a discounted rate.

Walker, a respected leader in commercial and supermarket refrigeration, delivers training to thousands of technicians nationwide. He has dedicated his entire career to refrigeration, with experience in corporate training and leadership roles, bringing hands-on expertise from his time at Heatcraft and Hillphoenix.
