This video frames the solution within typical operational contexts for clearer understanding. Watch as we demonstrate the Universal R404A Refrigerant Transportation Refrigeration Units with PERKINS Engine and Hot Gas Defrost for Trucks. You'll see how these units maintain precise temperature control from -18℃ to +25℃ for perishable goods transport, explore the robust engineering with industry-leading components, and learn about the efficient hot gas defrost system and electric standby capability in various application scenarios.
