Protector F1 Express 400ml

Product Code:
62418

Protector F1 is the market leading inhibitor which prevents corrosion and limescale formation in central heating systems.

This high performance product offers superior protection by uniquely combining three inhibitors of organic particles, which bind to the metal within the heating system to protect from debris alongside anodic inhibitors which react with the system’s metal surface to create a protective layer, and cathodic inhibitors that combine with hard water salts to form an insoluble layer. Fernox Protector F1 also includes enhanced a pH buffering to ensure the system water pH level does not drop below 6.5 or above 8.5 – the optimum pH range for preventing corrosion and limescale build-up. In line with local regulations and best practice, and for long-term protection of the system, concentration levels should be maintained and checked annually as part of the boiler or system service.

The Fernox Express range uses Barrier Pressure Pack technology and compressed air propellent to expel the product so the entire range is non-flammable. The propellent (compressed air) is not mixed with the active product so there is no risk of air ingress into the system which could accelerate future risk of corrosion. test dh

Application

One single dose of this product treats and protects a larger sized property with a heating system of 130 litres, up to 16 radiators or 250 sqm of underfloor heating and can be dispensed directly into a radiator air vent, system filling loop, or via a TF1 Filter using the appropriate adapter supplied with the product.

Fernox Express takes less then 30 seconds to dose the system without the need to drain down the system, saving time on-site. If dosing via a TF1 Filter, the filter should be emptied of any collected contaminants prior to treating with the product. In single feed indirect cylinder, e.g. Primatic; or similar, potable water chemicals must be used. Fernox recommends untreated or sludged systems are thoroughly cleaned and flushed in accordance with local regulations and legislation including BS 7593:2019 and Benchmark, using Fernox Cleaner F3 Express, before treating with Fernox Protector F1 Express, as existing debris can damage the installation.

Frequently Asked Questions
Make sure the system is turned off and allow radiators to cool down (1). Select a radiator and shut both the wheel-head and lock shield valves (2). If a thermostatic radiator valve (TRV) is fitted, close it by turning it to the minimum setting. Having removed the air vent pin using a cloth to absorb any escaping water (3). Screw the Fernox Express injection nozzle into the air vent (after cutting to the right diameter to fit tightly (4)). Fit the tube to the adapter and screw onto the canister. Attach the other end of the tube onto the nozzle in the radiator (5). Re-open the wheel-head valve (6) (or TRV) and inject all the content of the Fernox Express by squeezing the trigger for 30 seconds (7). After the product has been dispensed close the wheel-head valve (8) (or TRV), remove the injector nozzle and tighten the air vent pin (9). Open both radiator valves, turn on the central heating system (10) and let it run for 15 minutes to allow the Express to disperse around the system. Fernox Express can also be for dosed via the system filling loop using the appropriate special adapter supplied with the Express product as well as via the bleed valve on a fitted Fernox TF1 Filter. The whole process takes less than two minutes.
