A cross flow aeration system for aerating particulate materials disposed in a storage bin. The aeration system comprises a plurality of elongated hollow aerators. Each aerator is disposed inside the storage bin in proximity to an inside wall thereof having a substantially vertical orientation and has at least an opening for transmitting air from inside the aerator to the particulate materials. At least a blowing mechanism is in fluid communication with the plurality of aerators for providing the air thereto. At least an aerator air flow control mechanism may be disposed in each of the plurality of aerators for controlling flow of the air between a bottom section and a top section thereof. An elongated perforated venting tube is disposed approximately centrally within the storage bin. The venting tube extends generally upwardly to the bin roof for transmitting the air from the particulate materials to the bin roof and venting the same therefrom to a location external the storage bin.

Air handling system for a climate control system in a housing that includes at least a delimited space with controlled environment, CE space. The air handling system includes an air handling unit, AHU, a pipe system and a perforated plate assembly. The pipe system includes a branched tree-like structure of conduits, that branches in the direction from the air handling unit towards the perforated plate assembly for homogenous distribution of air over the perforated plate assembly such that the air flow through the perforated plate assembly into the CE space is an air flow under laminar flow conditions. Also, a climate system for climate control in such a delimited space, a modular unit including such a delimited space and such a climate system, and an assembly of modular units.

A method for assisting a distribution process by a distribution tool attached to a utility vehicle includes adjusting a position of a lower edge of the distribution tool by changing a lifting position of the distribution tool, determining by a sensor attached to the distribution tool a first distance between the lower edge and a surface region of the material being distributed, utilizing the first distance as a basis for adjusting the lifting position when the first distance has a value greater than or equal to zero, estimating a second distance from the lower edge of the distribution tool to the surface region based on the position of the lower edge resulting from the lifting position, and utilizing the second distance for adjusting the lifting position when the first distance has a value of less than zero.
