Why installers everywhere are switching to the tf1 sigma mini installer pack

Fernox has launched its TF1 Sigma Mini Installer Pack, giving installers everything they need to clean, protect and guard a central heating system in line with BS 7593:2019. Featuring the popular TF1 Sigma Mini filter, the pack is ideal for smaller volume systems with restricted space around the boiler, including social housing and new build properties.

In addition to the TF1 Sigma Mini, one of the smallest footprint system filters on the market, the pack contains trusted Fernox Cleaner F3 and Fernox Protector F1 265ml to clean and then protect up to 100L/12 radiators/190 sqm of underfloor heating. The pack also contains a Fernox Express Inhibitor Test Pack, making it simple to ensure the correct concentration of inhibitor is achieved to effectively protect the system.

One of the newest additions to the Fernox filter range, the TF1 Sigma Mini provides a solution for systems with limited space around the boiler in which to fit a filter as it only requires a 106mm pipework footprint. The filter is backed by an impressive 10-year warranty and has been engineered to protect the boiler from the damaging effects of circulating corrosion debris using a powerful neodymium magnet.

To make future servicing simpler, the TF1 Sigma Mini filter features a unique drain port which allows for quick and controlled cleaning or draining without the need to disassemble the filter. It also acts as a useful dosing point for the Fernox range of chemical water treatments. Available in 22mm and ¾” versions.

Mike Skivington Sales Director at Fernox commented: “At Fernox, we are committed to supporting heating engineers by simplifying the installation process wherever possible. The TF1 Sigma Mini Installer Pack is a perfect example providing everything professionals need in one convenient package, saving them valuable time on the job”.

Established in 1964, Fernox is a leading manufacturer of water treatment chemical products, central heating system filters, plumbing consumables and diagnostic testing services, and has pioneered the development of energy efficient products both for traditional and renewable technology in domestic and commercial applications.
