Regularly Inspect the Refrigeration Unit
Refrigeration unit is the backbone of your trailer, responsible for maintaining consistent temperatures. Thus, ensuring maintenance and extending the life of refrigerated trailers becomes mandatory.
- Check Refrigerant Levels: Low refrigerant levels can strain the cooling system, resulting in temperature fluctuations. Regularly inspect and refill refrigerant if needed.
- Clean Condenser and Evaporator Coils: Dust and debris reduce cooling efficiency. Clean thoroughly condenser and evaporator coils periodically to prevent performance issues.
- Inspect Compressor: Watch out for unusual noises or vibrations from the compressor as they can indicate wear or damage.
Monitor Insulation and Door Seals
Maintaining proper insulation ensures energy efficiency and stable internal temperatures. Any defect in insulation can pay way for some common refrigerated trailer issues like air leaks and fluid leaks, thereby negatively impacting the refrigerated trailer performance.
- Inspect Walls and Ceiling: Check for cracks or dents that can compromise insulation and allow heat to seep in.
- Regularly Check Door Seals: Worn or damaged door gaskets can lead to air leaks, forcing refrigerant units to work harder. Replace them promptly if worn out.
- Repair Damaged Panels: Any minor or major damage to the trailer’s walls or floors can affect temperature retention. Address these issues immediately.
Maintain Proper Airflow
Good airflow within the refrigerated trailer is essential for consistent cooling.
- Avoid Overpacking: Overloading the trailer can obstruct airflow, resulting in uneven cooling. Always follow recommended load capacities.
- Check Vents: Ensure air vents are clean and free for efficient airflow.
- Ensure Proper Stacking: Leave space between cargo and trailer walls to allow air circulation. Consider using pallets to keep goods off the floor.
Maintain Tires and Suspension
The condition of tires and suspension directly impacts the refrigerated trailer’s safety and performance.
- Regularly Check Tire Pressure: Underinflated tires can cause uneven wear and reduce fuel efficiency. Check tire pressure before each trip.
- Inspect the Suspension System: Look for signs of wear or damage in the suspension system to avoid uneven loads and maintain a smooth ride.
Perform Preventive Maintenance for Refrigerated Trailers
Routine preventive maintenance helps identify and resolve issues before they escalate.
- Follow Manufacturer Guidelines: Adhere to the maintenance schedule provided by manufacturer for inspections and servicing.
- Monitor Telematics Data: Use telematics systems to track the trailer’s performance, temperature, and location in real-time.
- Lubricate Moving Parts: Ensures locks, hinges, and other moving parts are well-lubricated to prevent rust and wear,
Keep the Trailer Clean
Floor of reefers accumulates all kinds of debris during transport. So, removing all the dirt after each shipment becomes important. Wash the trailer interior with a pressure washer and detergent if the shipment included meat and dairy.
