Osmolator 3 Nano Auto Top Off

The Tunze Osmolator 3 Nano is a compact and reliable auto top-off (ATO) system designed for aquariums up to 66 gallons (250 liters). It features a high-precision optical sensor that detects water levels with 0.5 mm accuracy, ensuring stable salinity and water conditions. The system includes a Turbelle® High Jet 5030 dosing pump with dry-run protection and a maximum delivery height of 20 feet, making it suitable for various aquarium setups. Installation is straightforward with all necessary components provided, and the unit is backed by a 5-year warranty, reflecting Tunze's commitment to quality.

Optical Sensor

The large, precise optical sensor detects the water level with an accuracy of 0.5 mm, resists air bubbles, deposits and scratches. Two levels of maximum dosing duration can be selected. This allows the dosage amount to be adjusted to the size of the aquarium. The sensor of the Osmolator® 3 nano 3151 holds on panes up to 12 mm (1/2").

Turbelle® High Jet 5030 Pump

Long-lasting high-tech dosing pump Turbelle® High Jet 5030 with integrated dry running and blockage protection, a maximum delivery height of 3 m (9.8') and pleasantly quiet operation thanks to a real 3-phase sine wave.
