Ventilation systems built according to the silo capacity and
the characteristic of the grain to be stored are installed into the concrete
during the laying of the foundation concrete. The secanals are coated using
specially twisted and perforated Magnelis sheets specially designed for the
product.
OBIAL uses ALFAN branded radial and axial fans in varying
capacities to ventilate the products stored in the silos of varying sizes and
capacities.
OBIAL ventilation chimneys allow for the easy discharge of
dust formation and pesticides inside the silos. These chimneys are sloped, with
wire curtains on their front surfaces. The securtains prevent birds and other
foreign objects from penetrating into the silos. And thanks to its sloped structure,
it prevents rain and snow to penetrate.
Where more air outlet is needed, OBIAL produces ventilation
fan with a wing diameter of 560 mm. This fan’s air suction direction contains a
wire curtain, with the air outlet direction having a louvered structure.
Louvers open during fan operation, and are designed so that they are shut when
the fan stops.
OBIAL also produces
portable tunnel ventilation canals strengthened by corrugating and joining zinc-plated
sheets to solve the ventilation problems in horizontal grain storages.
