Walfront DIY Mini Thermoelectric Cooler Semiconductor Refrigeration Module Thermoelectric Peltier Refrigerator Radiator Fish Tank Cooler Device Fan Cooling System(120W for 30L Fish Tank)

• This thermoelectric cooler uses high-end refrigeration module which has high power and good durability
• Cooling block has large area that can contact more water for quick cooling
• Four hollow copper pipes with refrigerant inside would deliver heat fast for higher cooling efficiency
• 120W is suitable for 30L fish tanks and 180W is suitable for 40L fish tank
• It is energy saving and beneficial to the growth and reproduction of ornamental fish

All for Better Cooling Effect Four Hollow Pure Copper Thermotubes contain refrigerant fluid which ensures high speed heat transmit; gains high-end refrigeration plate which provides higher power, cooling efficiency and better durability. The number of aluminum alloy is quite large, and the contact with air is even larger. Fin-shaped inner structure of the theremoelectric cooling unit provides bigger contact with water, so water can be cooled more thoroughly.
