Air coolers with axial fans

For the dry storage of onions, a large barn is equipped with 15 air coolers with axial fans. At 9 meters height between the trusses of the steel structure, the units have finally been placed. The specially designed air cone of these suction air coolers ensures optimal drying of the dried conditioned air to the wide dry wall in the back of the room. This creates a homogeneous airfront of 4.5 to 15 meters wide. Behind the space, the air is forced through the channels pressed down and distributed over the storage boxes. The selected fans feature so-called Owlets and Winglets. The owlets provide a quieter fan, because the exhaust air on the blade is “damped” in vibration through this fan blade geometry. The winglets provide a better seal between the airfoil and the air cone, which increases the efficiency of the construction and little extra air losses occur between rotor and stator
