A chiller truck's power consumption is determined by its size, refrigeration system, and the temperature range required for the cargo. Depending on the cargo being delivered, chiller truck Dubai usually employ diesel-powered refrigeration systems that can maintain temperatures between -20°C and +10°C. Larger units need more electricity to maintain the specified temperature, with these machines often requiring 5–10 kW. Additionally, certain trucks could have electric refrigeration systems that utilize 3–7 kW. The refrigeration unit may also run on additional electricity from the truck's engine while it is being driven.
