About this item Fast Temperature Control The aquarium cooler utilizes a compressor and r134a refrigerant to control the water temperature within the desired range in a short period of time. The water temperature can be monitored in real time to help keep the tank at a constant temperature automatically. Rapid Heat Dissipation The aquarium cooler has a built-in fan and a large number of cooling holes on the side, providing powerful ventilation to effectively dissipate the heat from the compressor, ensuring that the compressor runs efficiently all day long without overheating. Low Noise The aquarium cooler is equipped with a copper compressor, which ensures the working efficiency and greatly reduces the noise, only about 40-50 dB. Cooling Temperature The cooling temperature is affected by the ambient temperature and the size of the fish tank. If you pursuit a better cooling effect and more rapid cooling speed please reduce water volume.The less water, the better the cooling effect. Widely Applications The water chiller is equipped with titanium pump, which can run perfectly in fresh and salt water. Widely used in aquariums, fish tanks, small hydroponic system, etc.
