This is our main filter model - a classic reverse osmosis with a subshell. The filter works on the basis of a reverse osmosis membrane, which removes literally almost everything from the water, except the molecules of the water itself. After that, through the fitting system, the initial, mineralized water filtered by a combined cartridge with polypropylene and activated carbon is added to the desalinated water (permeate). You regulate the amount of mineralized water in the permeate. The valve is spinning mineralization is muddied.

With this filter, you can adjust, change from 10 to the values of incoming water (if you have 250 mg/l water, then up to 230-240). To control the water for both the coffee machine and the coffee filter independently of each other – you can install two independent mixes. By setting espresso no higher than 110 mg/l, you can be sure that the coffee machine will not fail due to scale, and by putting about 50 mg/l through another batch, you will achieve the optimal taste for filter coffee.

At the same time, Hiwater RO-400 is probably the best system in terms of quality, convenience, simplicity and price of service among such solutions in the commercial water treatment market.

This system is suitable for roasters and coffee shops, which need to manage the mineralization of water and experiment with various indicators.

Like all complex tools, the filter requires periodic (at least once a week) monitoring and adjustment.

Check these parameters before ordering!

1. Water pressure in the water supply. It should be at least 3.5 atmospheres (check with the management company of your house or the landlord). If the pressure is less, then you will need a pump to increase the pressure.

2. Water quality (Find out on the website of the water utility of your city or using the TDS meter). If the water is above 300 ppm or you have information that the water is dirty, we advise you to put a mechanical cleaning filter.
