submersible aquarium heater

This product adopts dual-system temperature control, which is equivalent to 2 heating rods for temperature control. When the main temperature control system fails, the backup temperature control system is activated to ensure continued safe heating, which is safe and power-saving. Frequency conversion heating is similar to frequency conversion air conditioning.
