Maintaining transport refrigeration units is a necessity for any business that specialises in transporting perishable goods.

As retail and consumer demands continue to evolve over time, the need for carefully controlled storage and logistics processes grows. It’s incredibly risky and ill-advised to only service vital transport refrigeration units when they show signs of trouble — having them preemptively assessed and repaired is essential.

Here, we’ll go over a few of the reasons you should choose planned maintenance for your transport reefer units to keep your business safe from setbacks.

Maintenance Lowers Costs

A number of transport refrigeration failures can occur while a unit is in use, leading to unnecessary emergency repair costs to keep goods within the refrigerated space from spoiling. If perishables are affected, it will lead not only to lost freight, but lost clients and contracts as well — not to mention the hit to your bottom line.

Technicians tasked with performing regular maintenance on transport reefer units go beyond a mere visual inspection, servicing parts before they impact performance and keeping your machines in optimal order at all times. The following are a few of the issues commonly checked for during a scheduled transport refrigeration unit maintenance session:

Oil Conditions

Lubrication plays a pivotal role in the longevity of your transport refrigeration system. This is especially true for the compressor, engine and other moving parts.

Your transport refrigeration unit’s compressor should be inspected consistently to ensure it’s running properly. At regular intervals, your compressor’s oil should be changed as well. Ideally, this procedure should be handled by a professional to ensure it is done correctly.

Paying special attention to your compressor and timing oil changes correctly keeps it from failing due to overheating and friction. Without scheduled maintenance, your unit’s compressor will literally wear itself out, costing you much more to replace it than maintenance would have cost in the first place.

Dirt and Debris

Dirt, dust and other forms of debris can gradually find their way into your transport refrigeration unit’s parts, clogging fuel lines, inhibiting refrigerant flow and leading to larger, more costly repairs if left unattended.

Tubing failures from tube metering restrictions can cause further damage to your unit through overheating. Such restrictions can also make a number of problems appear by limiting the amount of refrigerant your condenser and evaporator coils have access to. Regular maintenance ensures clogs are caught before they cost you more.  

Fuel System

Maintenance of your transport reefer unit’s fuel system is essential not only to prolong its lifespan, but also to keep it running. If your unit has come close to running out of fuel, then there could be air in your fuel system, causing starting difficulties, engine missing and more.

A skilled maintenance technician can bleed the fuel lines and prepare them for use, saving operators the headache of diagnosing a stuttering unit in mid-transit.

Refrigerant Leaks

Leaking refrigerant can wreak havoc on your unit’s ability to maintain its temperature for extended periods of time. Instead of remaining at a fixed temperature for the duration of a journey, a transport reefer unit running low on refrigerant will start off close to its target and slip as pressure within the evaporator coil drops.

Dealing with leaks is fairly easy, but the trouble it can cause for delicate freight while on the move is more than enough reason to let professionals look at it before it becomes a problem.

Broken or Malfunctioning Drive Belts

The drive belt on your transport refrigeration unit breaking halfway to your destination can effectively ruin the trip. However, with regular maintenance, you should never have to deal with this issue at all.

Knowledgeable technicians will not only check for signs of damage to your unit’s drive belt, but also adjust the belt’s tension periodically, keeping it running optimally on every trip you make.

Transport Refrigeration Maintenance is Flexible

When it comes to keeping transport reefer units in working order, maintenance is a reasonably flexible approach. Emergency repairs are rarely flexible — they have to be handled immediately whenever issues come up.

Immediacy in emergency servicing costs more. If you need a transport refrigeration unit repaired on short notice, you can expect to pay a premium in overtime and last-minute parts provisioning fees. A maintenance routine is significantly more cost-effective, allowing you to plan ahead and have new parts purchased for less.

Choose Maintenance Over Mad-Dash Repairs

Discovering a transport reefer unit malfunction before or during a trip can be a major problem for any transportation company. Maintenance eliminates the risk of refrigeration systems malfunctioning when you need them the most.
