[Attention] - This aquarium water cooler is only suitable for ornamental aquariums and cannot be used in other places such as seafood and industrial liquid cooling. The lower the required water temperature, the less water is available.
[Application] - This water cooler for aquarium coolers has low power consumption, which can ensure that the water is wetted when heating or cooling. This aquarium cooler water heater can also be used to control the temperature of aquaculture of seafood, transportation, etc.
Three installation methods: 1. Automatic filtration of the aquarium. 2. Automatic filtering of the water pump. 3. Automatic filtering outside the aquarium. Three installation and connection methods make the water cooler suitable for more applications.
Numerous functions: the evaporator is made of corrosion-resistant pure titanium material, fresh water and salt water. The cooler is equipped with an automatic overcurrent shut-off protection system and a shut-off temperature storage system. After shutting down and restarting, the machine continues to cool according to the originally set temperature, which is suitable for all freshwater aquariums, environmentally friendly and emission-free.
High-quality filter: the cooler enters the wind from the front and from the side and the rear is the air outlet. The filter can filter out the dirty items in the air, so that they cannot get into the water, making the cooling effect better and the tank in better condition.
