The variable-frequency thermal defrosting unit is precisely temperature-controlled and highly energy-efficient. It features AI variable-frequency temperature control and is compatible with all scenarios. Users can customize it according to their needs, eliminating the waste of electricity bills. All models are equipped with a self-developed 4G Internet of Things remote monitoring system. Users can check the storage temperature and the operation status of the unit via their mobile phones. In case of any abnormalities, it will automatically issue an alert, enabling precise control of the cold storage operation without the need for on-site personnel. This completely resolves the pain points of "no one to repair the faults and no recovery of losses".
