While mechanically cleaning your cooling tower and chillers is important, using specialized biocides is strongly recommended.  

BIOGARD 800:Bromine based biocide is one of the more effective biocides at controlling and removing bio film, the thin layers of bacteria and slime that attach to water system surfaces.

Bio film can be costly to the life of your cooling tower. Bio Films compromises system performance by decreasing heat exchanger efficiency, increasing metal corrosion , pitting, and fouling tower film fills. Worse still, bio film can provide a food source for protozoa and other single-cell organisms that function essentially as bio amplifiers for Legionella pneumophila, the bacterial organism responsible for Legionnaire’s disease.

Conventional oxidizers degrade inhibitors, leading to corrosion, pitting and increased bio fouling of parts, such as heat exchanger bundles. BIOGARD 800 biocide allows scale and corrosion inhibitors to do their jobs more effectively.

Control of bio film means more efficient and safer operation of water systems, which is exactly what BIOGARD 800  was designed to do. It’s stabilization technology allows the product to generate deep into the bio film, beyond the protective outer slime layer, causing parts of the bio film to slough or break way.

Industrial and commercial cooling systems will benefit from less product waste, lower energy costs, and water consumption, less vapor-phase corrosion and extended equipment life.

BIOGARD 800 BIOCIDE PENETRATES AND REMOVES BIOFILM

This sloughing action eradicates both the bio film and its bacteria and leads to cleaner system surfaces than you’ll get with conventional biocides. BIOGARD 800biocide’s stabilization technology minimizes reactivity with system additives such as scale and corrosion inhibitors, allowing those components to do their job more effectively. In fact, BIOGARD 800biocide causes very little degradation of common inhibitors, unlike chlorine or bromine

BIOGARD 800 BIOCIDE IS MORE COMPATABILE WITH SCALE AND CORROSION INHIBITORS

BIOGARD 800biocide is also less reactive to system contaminants such as organics, dead bacteria, nitrogen-containing compounds and wood preservatives. It simply does not suffer from high-demand factors as traditional oxidizing biocides do. In pilot cases, unstabilized bromine dropped below 1ppm halogen in less than two hours after the slug dose, while BIOGARD 800biocides residual lasted more than five hours. The result is longer lasting residuals and stronger bridal activity to control bacteria and bio film.

BIOGARD 800 BIOCIDE RESIDUALS LAST LONGER

Cleaner surfaces, improved heat transfer and inhibitor performance, and fewer system upsets. It all adds up to lower total system cost with BIOGARD 800biocide.
