ETAline – The energy saving fan

ETAline – The energy saving fan

Saves energy І Saves space І Saves money

ETALINE is the first fundamental innovation in new ventilator product development in decades. The development goal was, through effective aerodynamics, reduce the energy consumption of the fan. The R&D was with intense use of advanced CFD (Computational Fluid Dynamics) software. The implementation of the calculation results made new design elements and manufacturing methods for the ventilators necessary.

ETALINE in its range of fans is with the highest efficiency and thus with the lowest power consumption on the market!

The main design elements

  • Rotor with adjoining stator

Unlike normal low pressure fans ETALINE has a fixed stator, which at rotor outlet converts unwanted turbulence into usable static pressure. This leads to a significant pressure and efficiency increase.

  • Three-dimensional, curved blades

ETALINE is the first ventilator in its performance segment with real, three-dimensionally shaped rotor and stator blades. This makes it possible for the rotor and stator to be ventilated correctly. The pressure profile in the blade surface can also be designed significantly more effectively and without loss.

  • Continuous meridian channel

The air stream always flows in the ventilator so that no loss-making displacements can form. The drive motors are housed in the stator hub, without disruptive influence on the aerodynamics of the rotor and protected from contamination. All conventional motors can be used. Voltage and frequency controllable AC motors and EC motors. The combination with different drive motors and the high aerodynamic efficiency of ETALINE sets new benchmarks for energy saving and efficiency.

ETAline saves space

The highly efficient, aerodynamic design also achieves high performance density. Therefore, the outer dimensions of the ventilator are equal to the connection diameter. When used as an INLINE ventilator, no additional installation space is required and it is aesthetically attractive if installed in full view. Compact dimensions are becoming increasingly important in times of explosive raw material and energy prices. Reduced use of valuable raw materials and lower transport volume. Smaller motor dimensions due to very high efficiency, lower material use due to high performance density and the use of saltwater-proof aluminium alloy (from model 400 mm) make ETALINE a „lightweight“ and significantly facilitates installation.

ETAline is complete

ETALINE is an Inline Tube Fan designed for direct installation to a duct system. Compared to conventional fans, whether forward or backward curved, ETALINE requires no additional housing. Thus there are no additional mounting pressure losses or expenses for a housing. On the contrary, via uniform, turbulence free airfl ow through a very effi cient working stator, the pressure losses in adjoining parts are lower. Two ETALINE in a distance of only 20% of duct diameter in serieswill achieve exactly twice the pressure build-up with unchanged high fan effi ciency.

ETAline saves money

A high effi ciency fan causes lower power consumption and thus lower operating costs. This is even more important when considering that electricity accounts for approximately 70…90 % of the lifetime costs. Extraordinary is that such an energy-saving product is not expensive, but usually more favourable in price than solutions with well-known fans.
