  • Patent number: 7179418
    Abstract: A device (100) for heat-treating water is provided, comprising a confined heating zone, a passage way (15) for transporting the water to said confined heating zone (23) so as to facilitate heating of the water, a controller (27) for preventing the heated water from leaving the device (100) until pathogens entrained in the heated water are killed; and an antimicrobial substrate (20) for preventing pathogens entrained in unheated water from leaving the device (100).
    Type: Grant

  • Patent number: 6831257
    Abstract: The present invention is a system that automatically controls the selection, start-up and operation of primary and secondary heating towers chosen from an array of heating towers having varying physical and thermal sizes. The automatic control is implemented via a programmable logic controllers (PLC). The PLC provides independent control for each heating tower irrespective of the tower being a primary or secondary heating source. Should the demand for heated water upon the primary heating tower increase to a rate that the primary tower cannot satisfy, the PLC maintains the operation of the primary tower and at the same time starts the secondary heating tower to meet the increased hot water demand. Once the demand has dropped to rates that the primary heating tower can once again maintain, the secondary tower is disabled.
