SOBO HC Stainless Steel Aquarium Heater

The SOBO HC Stainless Steel Aquarium Heater series delivers precise, stable, and reliable temperature control for aquariums of different sizes. Available in 300W and 500W models, these heaters are engineered for long-term durability and safe performance in both freshwater and marine environments.

Crafted from high-quality imported 304 stainless steel, the SOBO HC heaters offer exceptional corrosion resistance and rugged construction, making them ideal for continuous use in aquatic setups. The sleek stainless steel body is stronger and more durable than traditional glass heaters, reducing the risk of breakage while improving performance.

Each unit includes a built-in thermostat with automatic shut-off, enhancing safety by preventing overheating. The advanced thermostat system uses high-sensitivity imported bimetals that provide accurate temperature regulation across a range of 20°C to 34°C, with an accuracy of ±1°C. This ensures your fish and aquatic plants thrive in a stable and comfortable environment.

Inside, a high-resistance heating wire ensures uniform heat distribution throughout the aquarium, minimizing cold spots and temperature fluctuations. Efficient heating performance supports healthy aquatic life and contributes to the heater’s long service life.

Safety features include a double waterproof sealing ring and an IP68 waterproof rating, allowing the heater to be fully submerged without compromising safety or performance.
