TF1 Delta Filter helps heat retired housing development

  • 11 Dec 2015

The new Fernox TF1 Delta Filter has been installed at a 1960s retired housing development in Norwich, as part of a new heating scheme to provide a more efficient, effective and well-protected system.

Brewers Court is benefiting from a renewed communal heating system thanks to a joint venture between property service manager NPS, Norwich City Council and Gasway Services. 

Having discovered a leak on the previous system, the first task was to undertake the groundworks and replace the heating mains.

During the next phase, the Fernox TF1 Delta Filter was installed onto the existing 2” pipework to help clean out magnetite and non-magnetic debris from the existing system that serviced the bungalows and flats on the development.

The Fernox System Health Check service was also used to make sure that the old system was clean. This involved sending a sample to the Fernox laboratory where a fully analysis of the system water was carried out.

Once the boilers are eventually installed, the filter will aid the system’s overall effectiveness by prolonging the life of parts like the circulating pump, motor head and valve seating materials.

The system also includes Fernox’s Protector F1 chemical water treatment to work alongside the filter and protect against further corrosion and scale.

How the TF1 Delta Filter works

The filter provides three methods of filtration: magnetic, hydrocyclonic and automatic or manual air separation. 

The magnetic filtration is powered by a high temperature neodymium magnet. The hydrocyclonic action feeds the system water to the magnet.

Additionally, the filter offers the ability to automatically or manually deaerate the trapped in the system depending on the system design or preference.

NPS Senior Mechanical Engineer commented on the TF1 Delta Filter’s suitability for such housing sector applications. He said:“When working on sites that accommodate the elderly and vulnerable, it is imperative that any maintenance is carried out swiftly and that working order is resumed as fast as possible. The TF1 Delta Filter was so quick to install, which meant the heating wasn’t off for long at all. This is exactly what we’re looking for.”

As a result of the incoming Heat Network (Metering and Billing) Regulations, individuals will be billed for energy use. The system will therefore prove to be cost-effective for both Brewers Court residents and Norwich City Council due to its long lifecycle and energy efficiency.
