2. The refrigerator is equipped with an imported R290 compressor, which has a large cooling capacity, ensuring fast and efficient operation while maintaining a quiet environment.
3. Innovative hot air defrosting technology effectively defrosts from the inside out, including bottom heating for thorough cleaning.
4. The refrigerator adopts a double hollow three-layer glass door body and an optional electric heating defogging door, which effectively removes condensed water mist on the glass and keeps it dry and clear at all times. (Frozen type)
5. With its effective bridge design, the refrigerator can completely isolate cold air and prevent cold air loss when turning off the evaporator fan switch or opening the door.
6. The refrigerator adopts cyclopentane microcellular foaming technology, which has excellent thermal insulation performance, while improving energy efficiency and environmental friendliness.
7. The back plastic protective net design ensures smooth airflow and more uniform temperature distribution inside the cabinet.



Strong defogging effect guaranteed
The hot air flow of the compressor is backfilled to the condenser through a specific conversion device, covering from inside out
Instantly defrost and keep dry, while synchronously heating the door and window panels from outside to inside
Exchange, quickly eliminate frost and fog, make product display clearer
Adopting double-layer insulated glass to achieve insulation and cold locking, preventing the loss of cold air
More energy-efficient than regular refrigerators
