  • Patent number: 9528215
    Abstract: Systems and methods for supplying a variety of chemical products to a plurality of utilization points such as to washer extractors or washing machines includes utilizing an auxiliary flush mechanism that operates independently of a product supplying manifold so that the wash machines may be flushed in order to free the manifold to supply product to an otherwise waiting washing machine. The flush mechanism includes flush lines associated with respective washing machines and each line having an auxiliary flush valve and associated flow sensor which are configured to flush water through delivery lines leading to respective washing machines. The systems are configured such that a flushing of a washing machine or machines may occur while product is being supplied to a different washing machine via the central supplying manifold.
