Editor's bottom line:
“This chiller for aquarium is the best one we tested. In terms of quality, brand and price, we couldn't ask for more.”
Main Highlights
- Fish Tank Chiller: Water chiller for ice bath can achieve the most efficient heat exchange, suitable for fresh water and salt water. The water cooler monitors the water temperature in real-time, and the chiller's temperature can be well controlled at 32-122/0-50°C (the suitable temperature range for an aquarium), depending on the actual amount of water.
- Good Heat Dissipation: The two built-in fans can dissipate compressor heat well, so that the compressor can work efficiently for a long time. In addition, there are a large number of heat dissipation holes on both sides of the chiller, so there must be a space of 6 inch/15cm around the chiller to ensure good air circulation.
- Low Noise Run: With a compressor cooling design, the aquarium chiller may produce vibrations and noise during running. However, equipped with silent fans, the noise level is significantly reduced, making it suitable for placement in living spaces without disrupting everyday activities.
- Complete Refrigeration Equipment Set: This water chiller for cold plunge comes equipped with a water pump, water pipe, and connectors, allowing you to set up your cooling device immediately upon receiving the package, without the need to prepare additional accessories. This convenience makes it an good choice for novice fishkeepers and hydroponics enthusiasts.
- Perfect for Fish Tanks & Hydroponics: Widely applicable in both freshwater and saltwater fish tanks, as well as hydroponics in homes, hotels, aquariums, fish farms, and other settings. Suitable for various aquatic creatures, aquaculture, fish, crystal shrimp, corals, and jellyfish.
