For extreme high ambient temperature countries, like Gulf Countries, it is over +55℃ in summer, so it will be very important to choose a truck refrigeration unit designed to handle the stress of elevated external heat while maintaining the necessary internal temperatures. Here are some key considerations and recommendations:
1. Powerful Cooling Capacity
Look for units with high cooling capacity relative to the volume of the cargo space, as high ambient temperatures can challenge the system.
Units with a BTU rating or kilowatt capacity that exceeds standard models are recommended.
2. Dual-Temperature Units
If you're transporting different types of cargo that require varying temperatures, dual-temperature refrigeration systems can be useful. They allow for split temperature zones, helping maintain both frozen and chilled items in the same truck.
3. High-Efficiency and Reliable Compressor
High ambient temperatures will cause the system high pressure and Increase the load on the compressor, the discharge temperature will become very high. It is a big test for the quality and performance of the compressor. Therefore, it is necessary to choose a compressor brand with high quality and good durability.
4. Energy Management
Consider systems with energy-efficient designs that can reduce the strain on the truck’s engine and reduce fuel consumption.
Units with variable-speed fans can adapt to cooling needs based on external temperatures and cargo conditions.
5. Insulation Quality
High-performance insulation (e.g., polyurethane foam) in the cargo space is essential to keep the cool air in and the hot air out. Well-insulated units require less energy to maintain a consistent temperature.
6. Advanced Temperature Control
Smart temperature control systems can adjust cooling power based on ambient temperature, reducing the risk of failure when it’s extremely hot outside.
7. Durability and Reliability
Look for heavy-duty units designed to withstand high temperatures, vibration, and extended use without compromising reliability.
Hot-gas bypass systems can prevent the system from freezing up under extremely high heat, ensuring smoother operation.
Recommended Brands for High Ambient Temperature Units:
Carrier Transicold: Known for their advanced refrigeration technology and energy-efficient systems(Oasis and Xarios) that perform well in hot climates.
Thermo King: They offer models designed for extreme conditions, including the SB Series for high-ambient areas.
SuperSnow(Kaixue): Known for powerful refrigeration units ‘H’ series that handle high heat conditions.
