YPS 250 Process Systems Heat Exchangers

YPS 250 – Heat Exchangers

Who this course is for
This course is designed for industrial refrigeration technicians, operators, engineers, and system designers who work with condensers, evaporators, and secondary refrigerant systems. It is applicable to food and beverage, cold storage, process cooling, and industrial refrigeration facilities.

Why this course matters
Heat exchangers determine how efficiently a refrigeration system moves heat, and small design or operating compromises can result in large energy penalties or reliability issues. Understanding how heat exchangers actually perform—rather than how they are rated—is essential for troubleshooting capacity shortfalls, high condensing pressures, unstable evaporators, and excessive pumping costs. This course emphasizes practical behavior under real operating conditions.
