High efficiency climate control High Efficiency Radiators Aquarea Air terminals are extremely slim. With a depth of just under 13 cm they are at the cutting edge of the market. Blending easily into the home, Aquarea Air's elegant design, and product refinements are clear to see in every detail. Its particular slimness has been obtained thanks to the innovative layout of the ventilation unit and the heat exchanger. The fan is tangential with asymmetric blades and the heat exchanger has large surface, enabling high airflows to be achieved with low pressure loss and and low noise levels. Exceptional ventilation efficiency means the motor uses considerably less energy (low wattage). The fan speed is continuously modulated by the temperature controller with proportional integral logic, with undoubted advantages for regulating the temperature and humidity in summer mode.
