Condensate pan treatment for 20 ton systems
This gel tablet is formulated to prevent slime growth and mineral deposits inside condensate pans used with 20 ton HVAC equipment. It also eliminates foul and musty odours that can develop in drainage areas. The product is supplied as a single yellow tablet weighing .2 oz. It is intended for professional maintenance of commercial cooling installations.
Up to three months of continuous protection
Each tablet slowly releases active ingredients that inhibit biological build-up and keep drain lines clear for up to three months. This reduces the frequency of manual cleaning and helps maintain consistent condensate flow. The gel format stays in place within the pan without dissolving too quickly. No additional chemicals or dispensers are required for the treatment period.
Simple drop-in installation
Place the tablet directly into the condensate pan where it can contact standing water. The main installation error is positioning the tablet where high-velocity water flow can erode it prematurely. Ensure the pan is free of heavy debris before adding the tablet so the gel can distribute evenly. Regular inspection every three months confirms when replacement is needed.
