ETH 300 Inline

Hydor ETH 300 Inline is the invisible heater for large nature creations (up to 300 liters). In addition to freeing the rear view from bulky glass tubes, the PTC (Positive Temperature Coefficient) technology of the filament prevents disastrous and lethal short circuits due to accidental dry overheating.

Key Features

• External Heating: Connects directly to external filter tubing, keeping the aquarium free of equipment.
• Safe PTC Technology: Self-regulating Positive Temperature Coefficient heating element prevents overheating.
• High Precision: Micrometric regulation dial to maintain a constant target temperature.
• Hermetic Connection: Secure screw-on hose connectors to prevent any inline water leakage.
