Refrigerator trucks should be used to transport sensitive products like milk, drugs, and food. The trucks assist in the safe delivery of perishables in good condition throughout transit even in extremely high temperatures. Despite all this, a good defrost cycle must be provided to maintain an uninterrupted cooling system. Ice build-up in the cooling system can impede air flow and reduce the efficiency of the refrigeration unit. It is for this reason that Indian business companies operating in truck containers in India should be familiar with defrost cycles.
What is a Defrost Cycle?
Defrost cycle is a process by which ice is melted from the evaporator coils of a refrigerated truck.
When the cooling system of the vehicle is functioning, water in the air is frozen on the coils. Eventually, the ice will clog the cold air path, and the refrigeration unit will have to work harder and less effectively. The defrost cycle avoids this since it melts the ice and keeps the truck at the appropriate temperature for products transported within. Defrost Cycle Types for India’s Refrigerated Transport
Three simple Defrost cycles types are used on India’s refrigerated trucks
Automatic Defrost – Defrost is done at pre-set fixed time intervals in the system. There are temperature-detecting sensors included, and there is an automatic defrost cycle operation whenever necessary. It is applied in most contemporary refrigerated trucks and possesses a high enough lowest level of human interaction.
Manual Defrost – In this case, the driver or operator must manually switch off the cooling unit and allow ice to melt. Although the system is effective, it requires constant monitoring and can lead to random temperature drifts.
Hot Gas Defrost – It is a technologically advanced process in which the system diverts hot refrigerant gas to the evaporator coils to defrost the ice. It is a fast and effective process of ice removal without total shut-down of the refrigeration system.
Why Defrost Cycles are Important
Prevents Cooling System BreakdownIce accumulation in the evaporator coils lowers airflow and increases the load on the refrigeration system. It may result in system breakdown and the generation of excessive heat leading to chilled product spoilage.
Maintains Energy EfficiencyA perfect defrost cycle maintains maximum efficiency of the refrigeration equipment, conserving fuel and lowering operational costs. Companies searching for a trusty cold storage plant in Mumbai value power-saving cooling equipment to save on expenses.
Maintains Product QualityFor food, pharma, and dairy applications, temperature is the most critical factor. Defrost cycle failure can result in asymmetrical cooling, impacting product quality and stored product safety.
Increases Equipment Life Gross defrosting reduces the load on the refrigeration unit, preventing excessive wear and tear of refrigeration equipment. Refrigerated trucks in India are prolonged while maintenance is reduced.
Best Practices of Defrost Cycle Operation
For best operation of refrigerated trucks, the following best practices must be adhered to by companies:
✔ Ice Build-Up Check – Inspect evaporator coils for icing on a regular basis. Excessive ice formation could be an indication that the defrosting system is faulty.
✔ Alter the Correct Defrost Interval – Alter defrost cycle based on load type, humidity, and ambient weather. Higher humidity levels introduce higher ice formation and thus higher defrosting.
✔ Proper Insulation – Insulated truck containers in India maintain a uniform temperature and do not go through multiple defrost cycles.
✔ Routine Maintenance Inspections – Schedule regular checks of the refrigeration unit to verify that all its parts, including sensors and defrost timers, function properly.
✔ Selection of the Ideal Truck & Manufacturer – Having a renowned cold storage manufacturer in mumbai enables companies to have top quality reefer trucks with increased defrost technology.
