Summer is Sizzling Hot…. Is Your Reefer Ready??!!

As the summer sun cranks up the heat, it’s time to get your reefer trailers ready for action. Don’t worry though, Desert Trailer Systems has your back with some handy tips on how to prep your semi-trailer and keep things chill this summer!

Desert Trailer Systems has been in the valley since 1983 and we have knowledgeable staff eager to share tips and tricks to keep your business going! As we all know, summer heat can rise up to 120 degrees, so pre-trip inspections are an important essential for preventing a breakdown. Let’s get started!

The sweet sound of humming refrigeration units and the frosty cargo on scorching summer days is the start of a great day! But, before you hit the road, it’s essential to give your reefer trailer some TLC. One way to do this is through a DOT inspection which is a comprehensive assessment of a commercial vehicle’s safety and compliance with regulations.  These inspections cover a range of critical components that are essential for safe operation on highways and roads. Here are the essential items to inspect on a semi-trailer reefer unit:

  • Overall Trailer Condition: Check for any signs of damage, corrosion, or structural issues on the trailer body, including the floor, walls, and roof.
  • Refrigeration Unit: Inspect the refrigeration unit for any leaks, damage, or unusual noises. Ensure that it starts and operates smoothly.
  • Temperature Control Settings: Verify that the temperature control settings are accurate and function properly according to the requirements of the cargo being transported.
  • Fuel System: Check the fuel tank and fuel lines for leaks, damage, and proper connections. Ensure that the fuel level is adequate for the duration of the trip.
  • Electrical System: Inspect the electrical connections, wiring, and components of the reefer unit for any signs of wear, damage, or corrosion. Test the battery and charging system.
  • Cooling System: Check the condition and cleanliness of the condenser and evaporator coils. Ensure that airflow is unobstructed for efficient cooling.
  • Refrigerant Levels: Verify that the refrigerant levels are within the recommended range and there are no leaks in the refrigerant systems.
  • Door Seals and Gaskets: Inspect the door seals and gasket for any signs of wear, damage, or deterioration. Ensure that they provide a tight seal to prevent temperature leakage.
  • Temperature Recording Device: If equipped, check the functionality of the temperature recording device (data logger) and ensure that it is properly calibrated.
  • Safety Features: Verify the operation of safety features such as emergency shut-off switches and alarms for high or low temperatures.
  • Exterior Lights: Ensure that all exterior lights on the trailer are operational, including clearance lights, brake lights, and turn signals.
  • Tire Condition: Inspect the tires for proper inflation, tread depth, and signs of wear or damage. Replace any worn or damaged tires.
  • Brake System: Check the brake system for proper operation, including air brakes if applicable. Inspect brake pads, drums, and lines for wear and leaks.

These are a few essential items to add to your checklist. Additionally, with every load, it’s always recommended to pre-run the unit and cool the trailer to your desired temperature, maintaining it to ensure your unit functions correctly and effectively refrigerates and will perserve your cargo.

Regular Maintenance and thorough inspections of both the trailer and the reefer unit are essential to ensure the safe and reliable transportation of temperature-sensitive cargo. Be sure to address any issue promptly and complete regular maintenance to help prevent delays or spoilage of goods.
