Abstract
An improved method and apparatus to prevent clogging of condensate drain lines with a biocide delivery system that prevents the growth of bioorganic growth in the liquid trap using time release biocide tablets or liquid biocide. When using solid biocide tablets erosion and dissolution of the tables is reduced. When using liquid biocides, combination of initial release followed by gradual release of residual liquid biocide in the drain water is attainable. Drain line are promoted from clogging while being installed anywhere on the drain line upstream of the liquid trap. The apparatus can also be incorporated with a liquid trap, allowing placement anywhere in the drain line.
Claims17
An apparatus for eliminating clogging of condensate drain lines or humidifier overflow lines by preventing growth of biological agents, mold, and fungus in a liquid trap, comprising a housing configured to accommodate a liquid biocide and allow for immediate dispersion of a predetermined portion of the liquid biocide while also providing for gradual release of the remainder of the liquid biocide which is retained in the housing as to disperse by dilution.
An apparatus for preventing clogging of condensate drain lines or humidifier overflow lines, comprising a device configured to dispense liquid or solid biocides and to provide a liquid trap to seal off an inlet with trapped water.
