Revolutionary technology for maintaining commercial and industrial cooling system drip pans. Algae growth is minimized by the presence of these strips that can be placed anywhere in the condensate pan except over the drain hole. Our non-chlorine formula helps eliminate any corrosion potential to the system. Normal strip life is 4 to 6 months depending on the system and the operating conditions. Use one (1) two ounce strip per five (5) tons of system capacity. Easy to use and economical for commercial building operators, hospitals and nursing homes and all commercial businesses where overflowing drip pans can ruin ceilings, carpeting, floors and spread uncontrolled bacteria and odor.
