Drive-In /Drive-through Racking System provide maximum storage capacity using the minimum amount of space. This Rack system is particularly suited to store very large quantities of homogeneous enzyme products. Drive-In Rack system consists of continuous lanes of racking with only a single load and retrieval aisle. Drive-In racking operates on the basis First In – Last Out (FILO), therefore it suits only product, stored in sufficient volume to require multiple lanes to ensure stock rotation. When operating Drive-Through racking, access aisle are positioned on either face of the Drive block. Drive-Through racking offers the advantage that picking and replenishment can take place independently of each other, allowing First In – First Out (FIFO) principals to be operated.
