Designed for use with Fernox TF1 in-line system filters or other similar filters, this unique inhibitor package includes an active dispersant which is proven to aid the safe collection of corrosion, debris and scale via a filter. This inhibitor product enhances the performance of a system filter whilst offering full protection against corrosion and scale formation. This innovative, proven formulation also extends system life and maintains optimum efficiency, while still being an environmentally friendly formulation. Concentration levels should be checked as part of the annual maintenance system service.
The recommended ‘in use’ concentration of Protector+ Filter Fluid F9 is 0.265%. One 265ml bottle will treat an average domestic system (100 litres). For open vented systems add via the feed and expansion tank. For sealed systems add via a suitable dosing point (e.g. a towel rail, or an in-line TF1 system filter). Alternatively, use a suitable dosing vessel to inject the product into the system. In single feed indirect cylinders, e.g. ‘Primatic’ or similar, potable water chemicals must be used. Fernox recommends that untreated, or sludged systems are thoroughly cleaned and flushed using any product from the Fernox cleaner range, before treating with Fernox Protector+ Filter Fluid F9, as existing debris can damage the installation.
Fernox Protector+ Filter Fluid F9 must be used with the Fernox TF1 Filter range, or other in-line system filters. Use in microbore systems is not recommended. Fernox Protector+ Filter Fluid F9 is an enhanced corrosion inhibitor, combining corrosion inhibition with dispersant properties. It is specifically formulated to prevent settling and aggregation of corrosion deposits and contaminants within central heating systems, to deliver the debris directly to an in-line filter (such as one from the Fernox TF1 Filter range) for fast removal and containment. This function allows systems to run more efficiently by minimising the settling of debris in low flow areas such as radiators, which causes cold spots, and facilitates further corrosion underneath the debris.
Protector+ Filter Fluid F9 gives long-term protection of domestic central heating systems against internal corrosion and limescale formation. It is suitable for all types of boiler, radiators and pipework systems. Protector+ Filter Fluid F9 is compatible with all metals and materials commonly used in central heating systems. It is suitable for use with all types of water, including softened water and deionised water.
Protector+ Filter Fluid F9 has been formulated to have best-in-class pH buffering ability, which keeps system water pH between 6.5-8.5, providing optimum protection for mixed-metal systems. Protector+ Filter Fluid F9 levels should be checked annually. The concentration of the product can be easily measured on-site using a Fernox Protector Test Kit, or by using the Fernox Water Quality Test postal service. After five years, systems should either be re-dosed, or a laboratory test performed, such as the Fernox Water Quality Test.
