What is a Side Stream Filter?

A Side Stream Filter helps in removing both soluble and insoluble metals together with debris over a period of time through a series of variable micron rated filters. The side stream filtration unit comprises of a filter housing, suspended magnetic filter bag that works to filter the hot or cold water system.

The Hydro-Fil Mini side stream filtration unit is a free-standing, self-contained compact side stream filtration system for chilled water system. It offers versatility, value engineering and compliance with BSRIA.  The Hydro-Fil Mini filters heating or cooling water systems. Such as cooling towers that can be filled up to 34,560L in volume.

Made in the UK to the latest BSRIA Guidelines


How does side stream filtration work?

  1. The hydro-fil mini, side stream filtration unit has two valves.
  2. Each compartment contains a filtration mechanism.
  3. The first compartment contains a rare earth magnet, which helps to remove both soluble and insoluble metal.
  4. The water then passes through the stainless steel plate into the second compartment.
  5. This contains the bag filter which traps other non-magnetic debris.
  6. Thereafter, the clean water will then flow back into the cooling or heating system.

Side Stream Filter Backwash

Our side stream filtration unit continuously and progressively cleans the heated or chilled water systems as water flows through. This is also referred to as a side stream filter backwash.

Different pressure can easily be measured across the sidestream filter bag to determine the water flow rates and gauge the filtration rates accordingly. This helps to determine when the filter bag requires changing.

Our side stream filter for cooling towers is also designed in such a way that you can easily check and clean the suspended solid magnetic bar. This bar attracts any metal found in the water coming from a cooling tower, or other cooling system, or heating systems.

Our Customers see Hydro-Fil Mini Side Stream Filters as incredibly useful water treatment solutions. That’s because they give more life span to the heating and cooling systems (e.g. cooling towers).

Some also see it as good alternative for using any water treatment chemicals to treat water. With the use of backwash, they ensure your system is fully cleansed.

Why you need a side stream filter for a cooling tower?

  • Allows the cooling tower to perform at its maximum level
  • The side stream filtration system for chilled water system needs continuous filtering of the water, therefore removing harmful bacteria
  • Removes damaging debris and solids from the system in order to allow the water  to circulate unaffected
  • Reduces the rate of corrosion within the chilled water system
  • Heat efficiency is improved in the water loop with the Side Stream Filtration Unit
  • The need for cleaning is reduced (badly affected cooling towers can sometimes need cleaning monthly)

What’s the difference between the Hydro-Fil side stream filtration units DN20 And DN32?

The technical specifications listed above do apply to both Hydro-Fil Mini DN20 and DN32. However, the only difference between these two products is the inlet and outlet size of the connecting valves.

These valves pass water at full flow in and out of the Hydro-Fil Mini i.e. DN20 is 20 mm connection and DN32 is 32mm connections.
