In 2005, TCL established a joint venture with De'Longhi in Zhongshan, Guangdong Province to jointly develop and produce dehumidifiers and mobile air conditioners, and has now formed one of the world's largest professional production bases for dehumidifiers and mobile air conditioners. TCL dehumidifiers are all from the Zhongshan factory, the compressors for small-sized products are from Datong, Taiwan, and most of the products of 25L and above are equipped with compressors from Taiwan Ruizhi.
 
DEF25E is TCL's latest flagship released in 2017, and the price of nearly 3,000 yuan is not cheap. The dehumidification capacity is 25L, and the functional configuration is quite complete, with the addition of a wind deflector and support for the swing function, and the dehumidification and drying capacity is further improved. The working principle of the dehumidifier is the same as that of the air conditioner, there is a process of heat exchange, and the outlet air temperature is slightly higher than the room temperature, which is a normal phenomenon, not a product problem. The DEF25E takes advantage of this principle and provides a special catheter to support directional dehumidification, which can be used to dry shoes.
 
The DED12E and DED16E are small form factor series, with a dehumidification capacity of 12L and 16L respectively, and use an air purifier-style upward air outlet method, and the simple touch panel is also very intuitive and easy to use. If the dehumidification area exceeds 100 square meters, you can choose TCL's DET50EP, the dehumidification capacity reaches 50L of industrial grade, and the pump pressure upward drainage function is provided, the price is about 2500 yuan, and the cost performance is good.
