Defrost Pocket™:
Average defrost time reduced by 26%

When the defrost cycle begins, the Defrost Pocket™ drops down to seal the outlet.
By preventing heat loss from the heater, it significantly shortens defrost time.

Therefore, it provides the following cost-saving benefits:
1) Heater heat is retained inside the cooler, reducing both defrost time and energy consumption.
2) Because heat does not escape, the energy required for re-cooling is also reduced.

Defrost Pocket applied

• The Defrost Pocket™ blocks the cooler outlet, preventing heater heat from escaping.

Defrost Pocket not applied

• Natural convection causes heat from the defrost heater to escape while drawing in cold external air.

Using the Defrost Pocket™ can save an average of 730,000 KRW* per year per cooler.

* Based on a 20HP cooler, ‣ Temperature: -20°C ‣ Defrost cycle: 25 minutes, 4 times a day ‣ Electricity rate: 136 KRW/kWh.

Comparison of internal cooler airflow

When the Defrost Pocket™ is applied, cold outside air does not enter the cooler during the defrost cycle.
Without the Defrost Pocket™, cold air from outside continues to flow into the cooler, and heat from the defrost heater escapes, reducing defrost efficiency.

Comparison of internal cooler temperatures

Applying the Defrost Pocket™ blocks outside air from entering the cooler during the defrost cycle, allowing it to reach the target defrost temperature faster and reducing overall defrost time.
Conversely, without the Defrost Pocket™, the influx of cold air from outside the cooler delays the time required to reach the defrost temperature and reduces defrost efficiency.
