Keep your aquarium at the perfect temperature with this semiconductor cooler! It uses thermoelectric (Peltier) technology to chill the water, which is energy-efficient and great for sensitive fish that need stable, cooler conditions. Available in two power options: 120W for tanks up to 30 liters (about 8 gallons) and 180W for tanks up to 40 liters (about 10.5 gallons). It runs on 12V DC, so you'll need a compatible power supply (not included). The high-quality refrigeration module is durable and provides reliable cooling without the complexity of traditional compressor chillers. Easy to install and operate, it helps promote a healthy environment for your aquatic pets. Ideal for small to medium freshwater or saltwater tanks, especially in warmer climates or rooms where temperatures fluctuate. Give your fish the cool, comfortable home they deserve!
