- Product Features
- Bromgard is a unique range of multi-functional liquid cooling water inhibitors and special activators which can be matched to specific cooling system metallurgy and water supply characteristics. They incorporate corrosion and scale inhibitors, bio-dispersant to prevent fouling and a powerful bromine biocide to control microbial activity.
- Bromgard is the ideal treatment system to protect against Legionnaires’ Disease. A Bromgard treatment program comprises of an appropriately selected Inhibitor and Activator, and where needed, this may be augmented by an additional non-oxidizing biocide.
Applications & Uses

- Dosage Rates Information
- Like most film-forming corrosion inhibitors maximum protection is afforded if a pre-treatment period is adopted.
- BROMGARD 520 is dosed at 3 times the normal dosage for a period of 5 days at the start of the treatment program, enabling a strong film to be built up quickly.
- Similarly, should the normal dosage be interrupted for any length of time, an elevated dosage for a short period of time will re-establish maximum protection in the shortest possible time.
- BROMGARD 520 should be dosed to maintain a minimum reserve of 200ml/m³ in the system water at all times.
- The product should be applied through the COOLPLEX DG M dosing system which has been specifically designed to apply the correct dose level of BROMGARD 520 and ACTIVATOR to ensure optimum control of corrosion, scale and microbiological growth.
- Bromgard Applications
- The Bromgard Inhibitor is dosed to maintain a continuous residual in the recirculating water. This is most effectively done using a water meter controlled dosing pump drawing the chemical directly from the supply drum or from a bulk storage dosage tank.
- As well as this, the Bromgard Activator is dosed on demand to achieve the desired microbial control. Depending on the particular cooling system, this may be achieved either by intermittent time-controlled dosage or more often by Redox controlled dosage to maintain the desired continuous bromine residual (typically 1- 2mg/).
- Switching is easy as the Bromgard approach is fully compatible with most existing cooling water dosing equipment, simplifying program change.
- The Bromgard cooling water treatment program can be monitored by a standard bromine test kits so that the necessary adjustments can be made and compliance demonstrated.
