Equipped with Continuous Operation functionality as a standard
In the operation mode where the main refrigerator operates on its own, the sub refrigerator provides backup support during the main refrigerator’s defrost cycle to achieve continuous operation.
（While the sub refrigerator is providing backup support, the main refrigerator performs an off-cycle defrost.）
This continuous operation function enables efficient evaluation testing.
*This function provides both constant temperature control and constant temperature and humidity control when the dry-bulb temperature is from 10 to 40℃.
