A universal cleaner designed for use in commercial and HVAC heating and cooling systems, Fernox FC3 Cleaner can be used for pre-commissioning new installations as well as removing sludge, scale and circulating debris in existing or contaminated systems to improve efficiency levels and avoid damage to system components. This high performance , fast-acting cleaner is compatible with all commonly used metals and materials found in central heating systems, including aluminium. It is also suitable for use when powerflushing.
For optimum results, the entire system should be completely drainable. Fernox FC3 Cleaner should be dosed at a concentration of 1% and can be introduced into the system via a suitable dosing point. For pre-commission cleaning, circulate Fernox FC3 Cleaner for at least an hour at normal operating temperature. To remove sludge from existing systems, circulate under normal operating conditions, for up to 7 days until acceptable flow around the system has been achieved. Additional/repeat applications of Fernox FC3 Cleaner may be necessary if systems are heavily sludged. Drain and flush with cold water until the water is clear and the Fernox FC3 Cleaner has been rinsed from the system. Fernox FC3 Cleaner will usually be removed after three complete flushes. Finally, add Fernox FC1 Inhibitor (or an appropriate Fernox inhibitor) to prevent further corrosion damage and scale deposits.
