Product Description

The FERNOX 62436 is a corrosion and scale inhibitor formulated for closed-loop hydronic heating systems. Sold as the F1 Protector Express, this liquid treatment is added directly to the system water to protect ferrous and non-ferrous metals from corrosion, scale buildup, and premature component wear. The 13 oz single-dose container is sized for straightforward dosing in residential and light commercial applications. HVAC technicians and plumbers use this product during new system commissioning or as part of routine maintenance on hot water heating systems.

The F1 Protector Express is intended for closed hydronic heating circuits including boilers, radiators, underfloor heating loops, and fan coil units. It is compatible with systems containing mixed metals and is suitable for use in both new installations and retrofit service calls where water quality or system protection needs to be restored. The single-unit pack allows for targeted treatment of individual systems without excess product.
