ioniX mini FS Mobile Filling Stations
Chemical-Free Filling and Water Conditioning
ioniX mini FS is a compact filling station designed for domestic and light commercial heating and chilled water systems.
Using eleXion’s Xi+ ion exchange resin, the unit removes minerals and salts from fill water while helping raise pH at the point of fill. This supports low-conductivity, non-corrosive system water without the use of chemical additives.
The unit can be used during initial system filling, or for inline conditioning of existing circulating water. This makes it a useful service tool where system drain-downs are not practical, or where downtime needs to be avoided.
ioniX mini FS is suitable for systems operating in accordance with VDI 2035 and VDI 6044 water quality principles.
Why choose ioniX mini FS
How ioniX mini FS Conditions System Water
Ion Exchange Resin
01Fill water passes through eleXion Xi+ resin, which removes minerals, salts, hardness, chlorides, sulphates and nitrates.
pH Support
02The resin helps raise pH at the point of fill, supporting stable, non-corrosive system water without chemical additives.
Conductivity Monitoring
03Inlet and outlet conductivity meters allow engineers to check water quality before and after treatment.
Flow and Usage Monitoring
04Inline monitors display flow rate and total litres treated, helping track resin performance during filling or conditioning.
Inline Conditioning
05ioniX mini FS can also be used on existing circulating water, helping condition the system without unnecessary drain-downs.

Frequently Asked Questions
What is the ioniX mini FS used for?
ioniX mini FS is used for chemical-free filling and inline conditioning of domestic and light commercial heating and chilled water systems.
Does ioniX mini FS use chemicals?
No. The unit uses eleXion Xi+ ion exchange resin to demineralise fill water and support pH balance without chemical additives.
Can it be used for both filling and inline conditioning?
Yes. ioniX mini FS can be used during initial system filling and for conditioning existing circulating system water.
Does the system need to be drained down?
Not necessarily. ioniX mini FS can be used for inline conditioning where system drain-downs are not practical or where downtime needs to be avoided.
What does the unit monitor?
The unit monitors inlet and outlet conductivity, along with flow rate and total litres treated.
What water quality does it support?
ioniX mini FS supports demineralised, low-conductivity system water in line with VDI 2035 and VDI 6044 principles.
What does Xi+ resin do?
Xi+ resin removes minerals and salts from fill water while helping support stable, non-corrosive system conditions.
What does the resin remove from the water?
The resin removes minerals, salts, hardness, chlorides, sulphates and nitrates from fill water.
What sizes are available?
ioniX mini FS is available in different sizes to suit domestic and light commercial applications. Full sizing details are available in the datasheet.
Can it be used with other eleXion products?
Yes. It can be used as part of a wider eleXion water treatment approach and can also be used with the FTK fine filter for inline treatment and filtration of existing circulating water.
