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.
