Key Features
368L Storage Capacity
The refrigerator provides 368L of total capacity, with 303L dedicated to the refrigerator compartment and 65L to the freezer. This provides separate storage areas for fresh and frozen food while maintaining a double-door layout.
6-in-1 Convertible Storage Modes
The refrigerator offers 6-in-1 Convertible Storage Modes. These modes provide flexibility to adjust the available storage configuration according to different usage requirements.
Frost Free Cooling
The Frost Free system prevents the regular build-up of ice inside the freezer compartment. This removes the need for routine manual defrosting and makes everyday refrigerator maintenance more convenient.
Inverter Compressor
The CTC39S21AI uses an inverter compressor. Inverter-based compressor operation adjusts cooling performance according to the refrigerator's requirements and is designed for everyday refrigeration.
Two Cooling Systems
The refrigerator features 2 cooling systems. This provides separate cooling operation for the refrigerator and freezer sections and is one of the model's key cooling features.
Super Cooling Technology
Super Cooling Technology is included in the refrigerator's cooling system. It provides a dedicated cooling function for situations where additional cooling is required.
Multi Air Flow
The Multi Air Flow system circulates cool air through the refrigerator compartment. This helps distribute cooling across the storage areas rather than relying on a single airflow point.
2.5L Water Dispenser
The refrigerator includes a 2.5L water dispenser. This provides convenient access to chilled drinking water without requiring the main refrigerator door to be opened.
Fresh Up to 10 Days
The product is specified with a Fresh up to 10 Days feature. This is a stated food-storage feature of the CTC39S21AI and is designed around maintaining freshness for applicable stored food items.

Toughened glass shelves provide structured surfaces for storing food containers and other items. The refrigerator includes four refrigerator shelves according to the verified specification data.
Four Freezer Shelves
The freezer section includes four shelves. This provides multiple storage levels for organizing frozen food items.
Two Bottle Shelves
Two bottle shelves provide dedicated door storage for beverages. This keeps bottles organized separately from the main refrigerator shelves.
Vegetable Box
A dedicated vegetable box provides separate storage for fresh produce. This helps organize vegetables within the refrigerator compartment.
LED Freezer Lighting
LED lighting is provided in the freezer section. This improves visibility when accessing frozen food stored inside the freezer.
Door Alarm
The door alarm alerts the user when the refrigerator door is left open. This helps prevent the appliance from being unintentionally left open.
Anti-Bacterial Gasket
