Back in 2009, a customer in Latvia purchased two 6032ES-WIR bins with raised walk-in doors, each storing 2,443 metric tons of wheat. This year, he replaced one bin with a model 6064ES-WIR. At 18 rings rather than the previous nine, this bin accommodates 5,491 metric tons – more than twice his previous model – without increasing the footprint of the structure itself.
