Answer: Of course. Functionally, our self-contained cellar cooling units can be divided into two types: plug-in single cooling and constant temperature and humidity units. Single cooling type can only keep the temperature level in the cabinet, its small in size, flexible and convenient to install, especially suitable for wine cabinets under 3 cubic meters. Constant temperature and humidity units with built-in wet film humidifier and PTC heater, cannot only keep the temperature level inside the cabinet but also the humidity. It is the better choice for clients who have relatively high requirements for temperature and humidity of the cellar.
