Reefer containers help keep food, medicine, and other perishable goods fresh during transport. To make sure they work properly and last a long time, regular maintenance is important. Proper care reduces breakdowns, saves energy, and avoids costly repairs.
In this blog, we will share simple tips to keep your reefer container in top condition.
1. Check the Refrigeration Unit Regularly
The refrigeration unit is the most important part of a reefer container. It keeps things cool, so it needs regular checks.
What to check?
✅ Compressor & Condenser Coils: Clean them to remove dust and dirt. Dirty coils reduce cooling.
✅ Evaporator Fan: Make sure it runs smoothly and nothing is blocking it.
✅ Refrigerant Levels: If the coolant is low, the container won’t cool properly. Refill if needed.
✅ Temperature Settings: Check if the thermostat is working correctly.
How often?
📅 Every month for a quick check.
📅 Every three months for a professional service.
2. Keep the Inside Clean
A clean reefer container works better and prevents food contamination.
Cleaning tips:
🧼 Wash the inside with warm water and mild soap.
🧹 Remove dirt and ice from walls and floors.
🔄 Keep air vents open for better cooling.
3. Check the Door Seals
If the door doesn’t close properly, cold air can escape, making the refrigeration unit work harder.
What to do?
🔍 Look for cracks or damage in the door gaskets (rubber seals).
🛠️ Replace damaged seals quickly to avoid temperature loss.
🚪 Make sure the doors close tightly.
4. Monitor Temperature and Humidity
To keep goods fresh, the container must stay at the right temperature and humidity.
How to check?
🌡️ Use a digital temperature monitor to track changes.
📊 Keep a record of temperature readings.
⚠️ Set up alerts for temperature fluctuations.
5. Check Electrical Connections
Reefer containers run on electricity, so electrical problems can cause failures.
What to do?
🔌 Check power cables for any damage or loose wires.
⚡ Make sure the voltage is stable to prevent overheating.
🛠️ Get an electrician to inspect the system regularly.
6. Lubricate Moving Parts
Lubrication reduces wear and tear, keeping the unit running smoothly.
What to lubricate?
🛢️ Compressor parts for better cooling efficiency.
⚙️ Door hinges and locks to prevent rust.
💨 Fan motors to keep them running quietly.
7. Inspect the Container Body
Physical damage can affect insulation and cooling performance.
What to check?
🔎 Look for rust, dents, or holes on the walls and roof.
🛠️ Repair any damage before it gets worse.
🚛 Ensure the insulation panels are in good condition.
8. Be Ready for Emergencies
Reefer containers can sometimes fail unexpectedly. Having an emergency plan helps avoid losses.
What to include?
📖 A simple troubleshooting guide for common issues.
📞 Contact details of a technician for quick repairs.
🔄 A backup power source in case of electricity failure.
