ROTKAPPE immersion heaters are robust heating devices designed to maintain a stable temperature in aquariums, ponds, and aquaculture systems. Thanks to their high-quality construction, they are reliable and corrosion-resistant, suitable for both freshwater and seawater.
Main features:
Durable materials: stainless steel or titanium heating element depending on the model, protective tube resistant to shocks and corrosion.
Temperature range: typically adjustable from +18°C to +34°C, accuracy ±0.5°C for precise control.
Integrated control: adjustable thermostat or compatible with an external controller.
Safety: dry-run protection, watertight insulation, some models shockproof or shatterproof.
Accessories: suction cup or mounting bracket, cable with plug, operation indicator light.
Certification and warranty: compliant with safety standards, manufacturer warranty depending on model.
