5 Useful Tips From Reefer Repair Experts

Call In The Experts

Commercial reefers require preventive maintenance that goes a long way when you want your reefer unit to last. Reefers are a huge and expensive investment; the fleet owners cannot be careless in their maintenance as it will be one very costly venture. Call the mobile reefer experts before the reefer breakdowns, and prevent a significant loss of time, money and damaged goods.

Don’t think twice before you call in the emergency breakdown experts from Road Dogs, as they ensure your trip with your reefer runs smooth. Before you reach the expert reefer care and maintenance service providers, follow these 5 Useful Tips From Reefer Repair Experts to help avoid any costly inconveniences.

PRO-TIP 1
Monitor The Functioning Of Compressor Units
Detailed attention must be paid to the compressor’s functioning, a crucial component of the refrigerator system. The operator must closely inspect compressor units every six months to ensure that all components are in place and operating correctly.
Let us suppose you are facing the issue of more than expected faster rate of decline in the oil level in the compressor crankcase of the refrigeration system then it is an indication of leakage due to the following reasons:

Reasons with their possible solutions

• Nozzle or filter clogged- for smooth flow of oil, ensure that the nozzle in the oil return line or filter in the solenoid valve is cleaned off the dust, debris, grease, which can cause choking.
• Worn out piston rings/ liner: Oil carryover happens with worn-out piston rings, avail the services of certified technicians from emergency breakdown service & get renewed the compressor piston rings or liner without any delay.
• Oil Foaming: Oil Foaming may arise due to liquid refrigerant entering the crankcase. Replenish oil and troubleshoot the cause of fluid in the compressor’s suction.
• Overall the fleet owners must pay close attention to worn-out contact points regarding the electrical components. If they believe that specific parts require immediate attention, then visit our website and call us at the earliest.

PRO TIP 2
Reduced Cooling Capacity
The cooling capacity of the reefer unit cannot be compromised in any way to avoid the damage of specific temperature maintained goods. Suppose after inspection by the operator it is has come into notice that the cooling capacity of the plant has reduced considerably which will not be able to maintain the cargo hold temperature then look for the following-

Reasons With Their Possible Solutions

• Inadequate refrigeration & damaged insulation: Charge refrigerant in the circuit and check and renew the insulation.
• Overpacked container- Do not pack the room above its capacity.
• Malfunctioning solenoid: Check its functioning and get it renewed by experts if not functioning correctly.
• Room door left open-Ensure to close the door while exiting the provision room.

PRO TIP 3
Unusual Sound from Compressor
If you hear abnormal sounds coming from some of the compressor parts, there is underlying trouble with mechanical components inside the compressor. Look for the possible causes of sound-

Reasons With Possible Solutions

• Sharp knocking sound when starting- Reduce the capacity control setting from high to low.
• The oil pressure is low- Without fail, ensure that the oil level is maintained and refill the lube oil as and when required.
• Stable foundation: The foundation of the compressor must be secured with all foundation bolts wholly tightened.

PRO TIP 4
Evaporator Coil Icing
The Reefer system can go down if there is the icing of the evaporator coils, which may happen due to:

Reasons With Their Solutions

• Temperature set too low- Increase the coil temperature by adjusting TEV, or it’s the sensor
• Less capacity of the coil- Install large capacity evaporator coils.
• Periodic Defrosting: Ensure the defrost system is functioning at regular intervals.

PRO TIP 5
Keep The Reefer Components Clean
This pro tip can extend the lifespan of the reefer unit to a great extent. Either take it as a DIY or call in the expert service providers, but whatever you decide, make sure that cleaning of the reefer components must be done on a regular schedule. Specifically, if you plan to do it yourself, make sure you clean the inside and outside surfaces with a mild solution of detergent and water at least once a month.

Not only will this help sterilize surfaces for food safety, but it will also contribute to more effective operating conditions for refrigeration equipment.

More than $3.5 trillion in cargo is transported through reefer containers. With this information, we understand the magnitude of keeping reefer in the best state by availing the services of mechanic maestros from Road Dogs. They have a vast knowledge of reefer maintenance and repair and know exactly what it takes to make your reefer operate smoothly all year round.
