  • Patent number: 5484510
    Abstract: A water distillation apparatus and method include an improved control system for operation and maintenance, condensers with plastic to metal seals between a plastic condenser manifold and metallic cooling tubes, and a filter with steam bypass to allow for easy sterilization of the filter and remaining distillation system. The control system includes a three pronged probe assembly for monitoring conditions within an evaporation chamber. One of the three probes monitors steam conductivity and provides a steam fault signal to indicate an upper level of contaminants in the steam. A purge pump is responsive to fault signals, including the steam fault signal, to pump water from the evaporation chamber.
