Tunze Osmolator 3 nano (3151.000)

The large, precise optical senso...

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").

Plug & Play

All required components are ready for installation in the package (except reservoir). No software setup required. The fixed parameters are based on many years of experience.

Includes Turbelle® High Jet 5030

Long-lasting high-tech dosing pump Turbelle® High Jet 5030 with integrated dry running and blockage protection, a maximum delivery height of 6.2 m (20.34') and pleasantly quiet operation thanks to a real 3-phase sine wave.

Hose included

The set includes a PU hose made entirely in Germany - low-emission, hydrolysis-resistant, microbe-resistant, flexible, but does not tend to kink when laid.

Compact all-in-one construction

With magnet holder and tube holder for an attachment to any aquarium edge or in the aquarium filter up to 12 mm (1/2"). The tube holder holds on up to 22mm (0.87")

5 years warranty

"Built to last" according to our highest standards. Our exclusive service is automatically included. Without registration and without hidden hurdles. And of course always accommodating instead of petty-minded.

Made in Germany

It doesn't matter whether it's the special plastic parts from our own injection molding department, the winding of the motor, the soldering of the coils to the electronics, the encapsulation, the assembly of the individual parts and the testing of each pump, the Turbelle® High Jet is traditionally manufactured at our headquarters.

Differences between Nano and Standard Osmolator:

Recommended tank size

• Osmolator 3 Nano (3151): Up to approx. 250 liters (≈ 66 US gal.).
• Osmolator 3 Standard (3154): For larger tanks (no fixed upper limit, significantly more robust for medium to large systems).

Sensors

• Nano: Only one optical sensor.
• Standard: Optical sensor + separate thermal/second optical safety sensor (for double overflow protection).

Safety shutdown in case of malfunction

• Nano: Very short timer shutdown (approx. 77 or 154 seconds, adjustable; then lockout until power cycle – pumps only a small amount of water before stopping).
• Standard: Longer timer (approx. 10 minutes) + second sensor as additional protection.

Pump

• Nano: Low-voltage dosing pump (slower, adapted to small tanks, quieter in normal operation, but sometimes perceived as louder).
• Standard: Turbelle High Jet 5030 (more powerful, higher delivery rate, up to approx. 6.2 m delivery height in boost mode, more robust and quieter at high power).

Flow rate / speed

• Nano: Lower (approx. 160 l/h max., slower refill process).
• Standard: Significantly higher (up to 180 l/h in boost mode, faster and suitable for greater evaporation).

Magnetic holder / glass thickness

• Nano: Up to 12 mm glass thickness.
• Standard: Up to 15 mm glass thickness (stronger magnets).

Plug / cable / workmanship

Nano: Simpler plugs (e.g., jack-like for the pump, cheaper cables, partly PVC).

Standard: Higher-quality, waterproof professional plugs (e.g., 3-pin Japanese plugs, polyurethane cables, made for wet locations).

Price

• Nano: More affordable (lower-priced Nano version).
• Standard: More expensive (premium version with more features).

Target group

• Nano: Nano and small tanks, price-conscious users, systems up to ~200–250 liters.
• Standard: Medium to large systems where maximum safety and durability are desired.
