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.
Claims11
An apparatus for eliminating clogging of a gravity-driven condensate drain line or humidifier overflow line and for treating a condensate drain pan or humidifier reservoir by preventing growth of biological agents, mold, and fungus, comprising a housing configured to accommodate a biocide wherein an outlet base located above an inlet base of the housing is continuously communicating with the condensate drain pan or humidifier reservoir so that a liquid level in the housing and the condensate drain pan or humidifier reservoir are at the same elevation and therefore form one continuous water body to allow dissolved biocide agents or other chemicals introduced into the housing to be diffusible into the condensate drain pan or humidifier reservoir.
