Chemical rod for hvac fluid conditioning system and method of manufacture

Abstract

An HVAC fluid conditioning system may utilize chlorine (or other chemical) rods to treat an HVAC fluid. The chemical rod preferably has a length longer than a width (or diameter) of the rod to prevent the rod from tipping within a receptacle of the HVAC fluid conditioning system. The chemical rod may have a substantially circular cross-section wherein the width is equal to the diameter of the cross-section. The rod may have a length longer than about three inches and a width or diameter of about one inch or less. The circular rod may be formed by placing a rod with a substantially rectangular (e.g., square) cross-section into a press and pressing the rectangular rod between two molds, each having a semicircular opening, to form a rod having a substantially circular cross-section. A releasing agent may be applied to the rod or mold to facilitate easy release.
