Hydronic Filtration Solutions
Why do you need side stream filtration on a closed loop system?
Water is the main means of closed system temperature distribution. It affects every single piece of equipment and every single person in the spaces that you manage.
Wherever there is closed loop system water four problems will occur: scale formation, corrosion, fouling and microbial growth.
Limescale deposits can clog up your heating or cooling system. Biofilm sludge or particles of rust and scale can also cause blockages and cold spots in pipes and radiators. All of this leads to reduced efficiency and high fuel bills. It also means extra stress on pumps, heat exchangers, radiators and sensors causing the risk of breakdown and inevitable expensive repairs.
Side stream filtration and a system water programme helps prevent all these issues. Filters reduce suspended solids and debris in the system water, which leads to less fouling. Decreasing suspended solids can also help reduce biological growth in the system because suspended solids are a good source of food for microbiological organisms. Decreasing biological growth in turn helps to reduce microbiologically influenced corrosion as well as scale formation.

If left untreated, dirty system water can increase your energy usage by over 10%.
What is an X-POT?
The X-POT is an award-winning, patented side stream filtration unit that maintains systems in accordance with BG 29/2021 and BG50/2021. The X-POT is an all-in-one solution that replaces the need for separate equipment such as:
- Magnetic Filters – In the primary chamber all magnetic particles are removed by a minimum of four powerful rare earth magnets, all encased in easy to clean 316 stainless steel.
- Cartridge & Bag Filters – The system water then passes through the stainless steel baffle plate into a secondary chamber where the fine filtration cartridge or bag captures non magnetic debris, biofilm and corrosive micro bubbles.
- Dosing Pots – The tundish on top of the primary chamber allows for easy dosing of the adequate water treatment chemicals required for the system.
- Dirt & Air Separators – The automatic air vent removes air accumulated in the system without the need for manual intervention preventing problems such as corrosion and cavitation in the circulation pumps.

By combining most current system filtration units into one easy install, easy-service, BSRIA acknowledged water conditioning product, the X-POT has multiple benefits including:
- Saving plant-room space with multi-functional design and retro-fit applications.
- Improving system life cycle and saving on capital expenditures.
- Enhancing system water quality leading to increased efficiency, significant energy savings and less operating expenses.
