The cabinet is constructed with an inner and outer layer, consisting of the outer cabinet and the inner cabinet. The outer cabinet is made of cold-rolled steel plate, while the inner cabinet is made of stainless steel plate. The shelves are made from stainless steel profiles. The water tank at the bottom of the inner cabinet is used for heating and auxiliary humidification. The humidification system primarily uses an ultrasonic humidifier, with water heating and evaporation as a supplement. The automatic control system, which includes a temperature controller and a humidity gauge, regulates cooling, heating, and humidification based on set temperature and humidity levels. The internal temperature and humidity are displayed on a digital gauge.
