The Royal League in ventilation, control and drive technology Fans for agriculture Durable, efficient, well designed

Achieving the best result with optimal ventilation Problems in agriculture Regular air exchange in stables, warehouse, silo or other agricultural buildings is indispensable for achieving optimal conditions for people, animals and stored products. Fans have to withstand the toughest ambient conditions in some cases. In order to meet these challenges and at the same time achieve the best possible result of the respective system for the operator, ZIEHL-ABEGG fans have been specially designed for agriculture. Challenges posed by ambient conditions ▪ High chemical exposure (including ammonia, hydrogen...

The Number 1 under extreme conditions Optimally tested for all loads In agriculture, fans are exposed to difficult ambient conditions. These include high chemical exposure to ammonia, hydrogen sulphide, dirt particles and high air humidity. That is why the agricultural fans of ZIEHL-ABEGG have been specially developed and designed for this application. Over 100 engineers work in our cutting-edge development and laboratory building, which houses the world's largest combined fan test bench. This is where the relevant data such as acoustics, air handling capacity, power consumption and other parameters...

IP55 ECblue - the new fully encapsulated motor generation The new ZIEHL-ABEGG fully encapsulated IP55 motor is specially designed for use in an agricultural context setting a new standard for reliable, modern and highly efficient fan technology on farms and in stables. Apart from the highest efficiency levels, the advantages of the new ECblue motor are an extraordinarily low noise level and a top-quality, compact external rotor motor design in aluminium die-cast. With an impressive additional power reserve, the new fully encapsulated ECblue motor meets all the requirements imposed on a fan drive....

Efficiency The fan efficiency is made up of motor, blade (aerodynamics) and electronics. In particular in the drive area, a highly efficient motor can dramatically increase overall efficiency. The ECblue external rotor motor is ideal here, being 15% more efficient over the typical output range. With the highly efficient ECblue drive, energy consumption and thus operating costs can be considerably reduced. The following diagrams show the difference. ECblue Motor Output in W Motor efficiency depending on electrical power The stables fan with direct drive by means of ECblue external rotor and integrated...

recouped after 2 to 3 years due to significantly lower operating costs. Over the entire service life of the fan, there is a cost advantage of over 40% (Diagram 3). With EC drives the specified temperature value can be complied with far more exactly since the speed is set in proportion to the control level. Phase-controlled 1~ asynchronous drives have a non-linear behaviour here. Control variants Speed controller with 0-10 V- or PWM input. Via a 0-10V or PWM input signal, the ECblue fans can be operated speed-controlled. The fan speed is then 0 – 100% accordingly. It is monitored and readjusted,...

System concept Optimized and matched from one source ZIEHL-ABEGG is the only fan manufacturer that develops processes for changing fan speed itself and produces the corresponding controllers. These include voltage controllers, frequency inverters and EC controllers. At ZIEHL-ABEGG, you can get everything relating to fans from one source. The components are developed, designed and selected so that the overall system is in harmony. Perfect interaction means durability, reliability, simple operation and energy efficiency. Resulting in individual solutions which offer crucial benefits in a special...

Control in the stables In the stables there is a wide variety of control solutions. Depending on the prevailing demands, wishes and structural conditions, different alternatives can be chosen from in most cases. The ZIEHL-ABEGG specialists will find the right solution for you for your respective requirements in on-site talks. The following are examples of two different fan control options for producing an optimum indoor climate in the various stalls or cots. Single exhaust air system with ECblue Central exhaust air system Fcontrol for speed control Motor contactor Chimney damper UNIcon air-con...

Application areas Fans in agriculture are usually divided into two application areas. The low pressure application area is characterised by low pressure losses, e.g. in chimney installation, wall fans, stable air circulation. The application area usually varies between 30-50 Pa. The high pressure application area is characterised by much higher pressure losses caused by long pipe lines or heat exchanger. The typical application area is at 150-200 Pa, which above all occurs in central waste air flow or waste air purification. For both areas, ZIEHL-ABEGG offers different fans optimized for the...
