Electronic Semiconductor Refrigeration Module DIY Cooler Cooling System Kit

In stock

Semiconductor refrigeration is a kind of refrigeration technology that produces negative thermal resistance, which is characterized by non-moving parts and high reliability. Semiconductor Refrigerator can be refrigeration and freezing, can make cold drinks, frozen cans, milk tea, water, etc.

This semiconductor refrigeration module can be refrigerated to freezing and can freeze Coke to 0.5 degrees.  it is power-saving and the low noise. our materials are the better material in similar products and can be used for a long time with electricity. Applicable to cooling small rooms, air cooling dehumidification, learning semiconductor refrigeration theory, etc, and You can use it to DIY a small fridge, mini air conditioner or cooling device.
