How many hours per week do you use the system?
Intensive use with hard water consumes a lot of resin — above a certain volume, nanofiltration or reverse osmosis can be more economical.
Less than 10 h/week
Occasional work or starting out
10 to 30 h/week
Several days per week
More than 30 h/week
Intensive daily use
Do you know the water hardness in your area?
Hard water uses more resin. If you do not know the hardness, select your country and province and we will estimate it for you.
Soft water
Below 250 ppm — north and north-west
Medium hardness
250–400 ppm — central areas
Hard water
Over 400 ppm — eastern, southern and inland areas
Very hard water
Over 550 ppm — areas with very high limescale

Select your country and province and we will estimate it
Estimated data based on the provincial capital. It may vary depending on your municipality.
Do you need to transport the equipment frequently?
Some systems include a trolley to make transport easier.
Few work locations
The equipment is moved infrequently or stays in the van
Routes or many work locations
I move it several times a day

HydroPower DI Calculator
What performance can you expect from a HydroPower DI with your water?
Enter your actual ppm or select your area to get an estimated guide to litres, working hours and surface area.
!
Guide values. The estimated ppm for an area may vary by municipality, water supply network and time of year. If you have a TDS meter, enter your actual ppm for a more accurate estimate.
ppm
Calculator range: 1–2,000 ppm.
The area value is an approximate reference, not a measurement taken at your property.
!
Performance is not guaranteed. Litres, hours and m² are estimates based on Unger reference data and the ppm entered. Actual performance may vary due to water composition, flow rate, resin condition and working conditions.
!
High resin consumption
At this ppm level, a HydroPower DI system may be uneconomical for regular use. We recommend considering a reverse osmosis system such as the Unger RO S.
Unger reference: incoming water TDS 275 ppm, output <10 ppm; laboratory values and approximate coverage. Values between reference points are calculator estimates, not an official Unger table.
