The Aquael Ultra Heater D&N is an aquarium heater designed for precise temperature control during both day and night. The innovative technology of this device allows for the maintenance of constant water temperatures or the replication of natural temperature fluctuations between day and night, as found in aquatic ecosystems. The features of the Ultra Heater Day&Night include a fully electronic system without susceptible mechanical components, an integrated thermal cut-off to prevent overheating, and a display that clearly shows both the current and set temperatures. The device is equipped with Smart Heating System technology that intelligently adjusts heating power as needed and ensures thermostat precision of +/- 0,25°C.

The modern, flat design of the heater seamlessly integrates into any aquarium's appearance, while the shatterproof housing ensures even heat distribution. Thanks to the DAY & NIGHT SENSOR, the Ultra Heater D&N intuitively adapts to light conditions and switches accordingly between modes. Users can choose between a constant mode, which maintains the same temperature throughout day and night, and a D&N mode, which allows for different temperatures during day and night. This feature creates conditions as close as possible to natural thermal environments by mimicking the daily temperature amplitude in the aquarium.

25w - 10-25L -      H = 6.4 / 16.3cm

50w - 15-50L -       H = 6.4 / 16.3cm

75w - 35-75L -       H = 8.2 / 20.8cm

100w - 60-100L -   H = 8.2 / 20.8cm

150w - 90-150L -   H = 10.8 / 27.4cm

200w - 130-200L - H = 10.8 / 27.4cm
