Profile: Pellcroft Engineering Ltd. specializes in offering crop drying and storage solutions. Our products include fans, grain walling, main air tunnels, floor laterals, grain stirrers, louvers, potato storage equipment, de-humidifiers, heaters, storage controllers and accessories. Levelair grids consist of a welded steel framework, with a dipped paint finish on which is welded a louvered or expanded steel cover. The Levelair H.D. uses a deeper and heavier section framework, but is otherwise identical. Typhoon Levelair floor grids are the ideal solution where below-floor laterals are required to allow an unobstructed floor area in the crop store for access by lorries and other traffic.
