The sprinkling equipment includes at least one bypass-type space polymer block with cells, with a hexahedron layout. The blocks are mounted in the cooler using connecting bars vertically pulled onto suspensions hanged to a bearing structure characteristic by the fact that each block (9) contains at least two bypassing layers (11) arranged vertically in the block (9) at a specific distance from each other. Each layer (11) is performed from a row of cell units (12) assembled in a dismantling manner by connecting teeth (13) to the connecting beds (14) of the baby squares (5). The former are fixed to the connecting bars (6) pulled over the suspensions (7) with expanding cases (17) between the bars (6).<IMAGE>
