Abstract

a presente invenção refere-se a um secador de ar de ferrovia que comuta o fluxo e contrafluxo de ar através de cada uma de duas torres de dessecante (46, 48) em resposta à umidade de ar real sendo seco pelo secador de ar. o secador de ar inclui um sensor de umidade (68), um sensor de temperatura (72) na saída de ar, e um sensor de temperatura (50) no fluxo de ar de entrada para determinar quando iniciar a regeneração do dessecante. o sistema de secador de ar está geralmente especificado para prover algum desempenho de secagem mínimo, por exemplo 40°c de supressão de ponto de orvalho.
