How to Get a Thermo King Reefer Going Again After Ut Runs Out of Fuel
Refrigeration trailers, likewise known every bit reefers, brand up a large, dynamic part of the freight and logistics industries. Without reefers, temperature-sensitive appurtenances tin only be transported a thing of miles from their starting location. That's not far when because that many perishable appurtenances these days travel hundreds of miles via reefers to make it at their destination.
Like whatever trailer, reefer trailers experience occasional bug that require attention. Attention to issues with reefers is particularly of import due to the sensitivity of products existence transported. If the problems relate to a reefer unit non cooling properly, it can effect in cargo becoming spoiled and unusable. That spells big losses for all stakeholders.
To avoid issues, information technology helps to be familiar with the most common problems associated with reefer trailers and what signs indicate that a reefer may need preventive maintenance.

Be Aware of Leaks
Leaks come in many forms, including fluid and air leaks. Since reefers incorporate several mechanisms that assistance in the cooling process, there is potential for leaks in a multifariousness of areas. If a reefer unit of measurement is non cooling properly, checking for leaks is a adept identify to begin investigating.
Fluid leaks
Like any vehicle, fluid leaks are a common trouble. Of course, it'southward always wise to check typical leak sights, like oil from the engine. When it comes to cooling issues, you'll desire to look in other areas for the source of leaks, particularly those that directly relate to the compressor and condenser that support the reefer's cooling abilities.
The post-obit are places to check for fluid leaks if there is a noticeable modify in reefer temperature:
- Equalizer Tubes:This controls the flow of liquid refrigerant entering the evaporator. It'due south an important component of the overall cooling organization, but also one of the first places to cheque for fluid leaks. If in that location is a leak from the equalizer tube, it is cause for business and maybe the reason for ineffective cooling.
- Cracked Cooling Hoses and/or Belts: Cracked, cleaved, or worn hoses tin exist a major source of business if a reefer is not cooling properly. There are many hoses and belts that make upwards cooling systems, both for refrigeration and engine function.
Also, check to come across if leaks are happening constantly, or only when the unit is ON or OFF. Leaks that occur at specific times may help to diagnose the problem more quickly.
Air leaks
Similar fluid leaks, air leaks are a common trouble in reefer trailers. If seals are ineffective, absurd air can escape the trailer and warm air can enter. It can exist easy to miss air leaks if reefers aren't receiving regular maintenance, so it's particularly important to stay on acme of having your trailer routinely serviced.

As well, be aware of hinges on doors. If they are broken or corroded, they may contribute to improper cooling.
Calibration for Sensors
Calibrators help to regulate temperature, and if they are faulty, it can result in a damaged load. Sensors assistance alarm drivers to whatsoever changes in reefer temperature, only fifty-fifty the sensors themselves tin can accept issues. If they give inaccurate readings or alerts are not given at the proper time, a reefer may not be cooling properly for an extended period, putting cargo at take a chance.
Condenser
Condensers act as oestrus exchangers. Just as a radiator helps to maintain a stable temperature for a motorcar's engine, a condenser acts as a support to maintain stable temperatures in reefer trailers.
There a number of components such as coils, clamps, bolts, and tubes within the condenser. Impairment to any of these parts tin be detrimental to the overall function of the cooling system.
Bulkhead Issues
Bulkheads are used to separate different types of temperature-sensitive cargo within the same trailer. If airflow through bulkheads is blocked or faulty, it tin affect unlike temperature zones within the trailer. This is especially concerning if operators are shipping different types of appurtenances that require varied storage temperatures.
Maintaining and Troubleshooting a Reefer Trailer
The beginning pace to avoiding improper cooling in a reefer is to receive regular maintenance. Check with the manufacturer to ensure that the reefer is being serviced at the recommended intervals.
Generally, information technology's best do to take service checks done every 90 days. During summer months, drivers may desire to receive more frequent service as the cooling systems take to work harder. Addressing problems before they worsen volition save time and coin and go along operators on the road with more consistency.
In add-on to regular maintenance, it's wise for drivers to begin each trip with an inspection of their own. It'south not uncommon to find pocket-size issues that tin can be addressed earlier loading cargo and thus forbid a lost shipment. Here are some simple items to bank check pre-trip:
- Check hoses, belts, and seals for cracks or habiliment
- Bank check for any visible leaks around or inside the reefer or its compressor unit
- Ensure that doors shut tightly and lock
- Bank check that displays are functioning and stand for authentic measurements and temperatures
For an added layer of protection against a reefer not cooling properly, drivers tin utilize thermometer sensors in the trailer. Placing them in different temperature zones and at the height, bottom, front end, and back of the trailer will ensure that the temperature being measured matches displays.
Reefer trailers that accept sensors with alarms can exist very helpful for drivers so they don't miss temperature fluctuations or maintenance issues.
Reefer Troubleshooting
Drivers who regularly operate a reefer trailer or other commercial trailers should be well-informed and educated about the trailer. Knowing how to perform simple maintenance if at that place are problems on the road tin can help preclude serious bug with a shipment.
One of the well-nigh important skills for troubleshooting is to have a thorough knowledge of how to read and interpret alerts from the cooling unit. Codes will indicate certain bug with elements in the reefer such as the bombardment, belts, or pressure level problems.
In addition to understanding how to read and operate all equipment within the reefer, it's helpful to continue UV coolant leak detector handy. If a driver believes that a leak is occurring but tin can't locate it by a unproblematic eye exam, using a UV leak detector volition illuminate the source of a leak.
