Unlike traditional air-conditioning systems, which cool the air within the premises, ceiling fans act directly on the occupants, cooling their bodies without changing the temperature of the room. This results in significantly lower consumption, with obvious advantages both in terms of the costs of bills and environmental impact. In addition, the absence of effects on ambient air temperature means that the ceiling fans can be effectively used to cool bodies in outdoor open environments, such as verandas, outdoor dining spaces or – for the livestock sector – stables.

he density of warm air is lower than that of cold air. This causes warm air to rise naturally due to the effect of convective motions, concentrating near the ceiling. This phenomenon, known as stratification, causes a considerable waste of energy in environments with extensive heights (warehouses, industrial buildings, lobbies, airport and the like) in the area subject to rigid winter temperatures, rendering it necessary to resort to heating systems, owing to the need to transfer additional heat to the layers of air at human height, to compensate for the upward flow of the warmer air.
The most efficient and effective way to solve the problem is to scramble the air by pushing the warmer layers near the ceiling down, an action known as destratification. Thanks to the ability to rotate at extremely low speeds, NORDIK HVLS SUPER BLADE fans are able to achieve the expected result by maintaining the air speed at human height at values below 12 metres per minute, preventing any discomfort.
The adoption of the electronic control unit VORT T, which integrates a temperature sensor, also facilitates the automation of the speed regulation of the NORDIK HVLS SUPER BLADE fans in accordance with any changes to environmental conditions.

The NORDIK HVLS SUPER BLADE series consists of various models, varying in terms of the nominal diameters, the power of the motors installed and the length of the blades suspended, being further enriched by a broad array of accessories for optimising use in a wide variety of potential installations, with areas of effectiveness ranging between 110 and 910 m2, corresponding to the circular surface area of amplitude equal to 4 times the nominal diameter of the unit.

Compared to the cheaper fans equipped with AC motors, EC brushless motors offer a number of advantages that can be summarised as:
· Significantly lower consumption;
· Wide adjustment range (from 10 to 160 Rpm) of the rotation speed, thanks to the integrated driver that renders unnecessary optional external devices that are expensive and complex to install and configure – adjustment merely requires a working potentiometer with a 0-10 V signal.
· Reduced maintenance costs, given the absence of gears in gearboxes that are often combined with traditional motors;
· An extensive range of installation alternatives, by virtue of the possible supply from single- and three-phase lines, at voltages between 200 and 480 V and at frequencies of 50 and 60 Hz;
· Possibility of integration into a Building Management System (BMS), thanks to the Modbus communication protocol, via the RS485 port integrated into the motor driver.

Fans of the NORDIK HVLS SUPER BLADE series can operate effectively in ambient temperatures between -10° C and + 50° C. The elevated (IP65) degree of protection of the motor against dust and water sources also renders these fans suitable for use in areas directly exposed to the elements.

The fans in the NORDIK HVLS SUPER BLADE series are produced tobe virtually “maintenance-free”.
Under heavy working conditions (such as continuous operation at top speed in the presence of particularly high temperatures and humidity levels), periodic inspection should be conducted (we recommend annually) to confirm the correct status of the device coupling the blade to the support that binds them to the motor.
