The new sealed and ultra-compact TF1 Sigma Mini, providing a practical filter solution for smaller volume systems with restricted space. With an excellent collection capacity to capture system contaminants, it is simple to install and service. By adding the TF1 Sigma Mini to the extensive Fernox portfolio, installers can now find a filter option to suit every requirement

Combining the quality of the Fernox brand with a simple, ultra-compact design, the new magnetic TF1 Sigma Mini from Fernox is ideal for social housing, new build properties and smaller volume heating systems. The filter comes ready-to-install and is easy to fit in under two minutes thanks to its slip socket manifold design. Ideally installed horizontally on vertical pipework, the sealed filter can be installed in tight spaces as it only requires a 106mm pipework footprint.

The filter also acts as a handy dosing point for the Fernox range of chemical water treatments, featuring a unique drain port which allows for quick and controlled cleaning or draining without the need to disassemble the filter.

Based on the technology of the original Sigma model and backed with an impressive 10-year warranty, the TF1 Sigma Mini is designed to protect the boiler from the damaging effects of circulating corrosion debris as well as provide installers with a compact option and performance they can trust. Featuring one of the highest kV values compared to filters of similar size on the market, the TF1 Sigma Mini is designed to ensure there is minimal pressure loss in addition to maintaining a high collection efficiency.

Ernie McDonald, General Manager at Fernox said: “The TF1 Sigma Mini is a superb addition to our filter portfolio and demonstrates our steadfast commitment to adapt and innovate. Whatever the type of system or scenario they are faced with on site, no matter how restricted the pipework or space around the boiler might be – installers can rely on Fernox for a high-performance filter and trusted chemical water treatments. All properties must be able to benefit from a clean and efficient central heating system and our extensive portfolio provides everything needed to get the job done.”
