Before the city fully awakens in the early morning, a white van quietly drives into a distribution center. Unlike the roar of traditional diesel engines, this vehicle operates almost silently, with only a slight hum of electrical current indicating that its refrigeration system is working. This signifies a comprehensive revolution in the cold chain logistics industry, from power sources to temperature control methods—electric refrigeration technology is changing the way vans control temperature, bringing a greener and more efficient future to the logistics industry.
