JEBAO ATO-150 auto top up

Description

Jebao ATO (auto top up) is a unique, small system with a non-contact digital sensor, which monitors and automates the refilling of evaporated water. The system uses AFS technology for fault protection.
It can be connected to a water refill container and automatically refills water from it when water in the tank/sump is low.
It can be easily used by mounting the sensor at the desired level and installing the pump in the water refill container and turning it on. When the water level in your aquarium or sump is too low, the system tops up the water up to the sensor and then turns off automatically. This process repeats itself every time the water level is too low.
The system even works in complete darkness. There are no moving parts and there is no risk of leakage voltage.
ATO150 is very small and work well in marine and freshwater.

Jebao ATO-150 Auto Top-Up for SG Reef and Sump Tanks

The Jebao ATO-150 automates the tedious job of replacing evaporated water, using a non-contact digital sensor to detect the level and a small pump to refill from a reservoir. In Singapore’s warm climate, evaporation runs steadily all year, and on open-top tanks or sumps you can lose a surprising amount of water in just a day or two. Topping up by hand causes salinity to swing on marine tanks, which an ATO neatly prevents.

Mount the sensor at your target level and sit the pump in a refill container, and the system holds the waterline steady so parameters stay stable while you are at work or away. The AFS fault protection is reassuring against accidental overfilling. Use treated or RO/DI water in the reservoir as appropriate, and check the sensor stays clean, since film build-up in warm water can affect reliability over time.
