Ecosoft RObust is the perfect solution for HoReCa


— because the purified water does not contain chlorine, pesticides, heavy metals, organic compounds, viruses and bacteria

— due to high capacity there is enough water for everyone 


— long service life due to lack of scale

— Up to 50% of dishwasher detergents consumption

It is a compact reverse osmosis filter with high capacity. It gives you the permanent access to pure and safe tasty drinking and cooking water.

3 stage filtering:

  • pre-filtration provides removal of sediment impurities, active chlorine, organochlorine compounds, as well as organic matter.

  • membrane treatment (RO element Dow Filmtec™) removes up to 99.8% of dissolved impurities, incl. viruses and bacteria.

  • activated Chemviron Carbon filter improves taste and odor.

Who are the users?

The combination of high performance and compact filter size is best suited for a large restaurant.

— Big amount of quality water

With this filter, you can get up to 3000 liters of purified water per day, which means there is enough water for everything, from a glass of tasty and refreshing water for guests to making coffee and various dishes.


— Appliances are protected

You will forget about scale, white streaks, streaked on glasses and glass surfaces. Your coffee machine, ice maker, dishwasher and other appliances will last 2 times longer.


— Guest will have a great pleasure

High-quality purified water without odor and impurities will reveal the true taste of dishes and drinks.


Reverse osmosis is the most reliable water treatment technology. Due to special semipermeable membrane we get an ability of sufficient drinking water purification of all kinds of harmful impurities, incl. viruses and bacteria.   RO membrane pores are 200 times smaller than viruses, and 4000 times smaller than bacteria.   


Filter operation is based in separation of feed water in two flows: purified water (permeate) and water with high impurities content (concentrate) which is dumped into the sewer.

Due to installation of 2 RO membrane Dow Filmtec™, RObust 3000 can provide not only pure water but also a really high capacity. That's why you don't need the pressure tank.

Filter has thoughtful visualized by pictographs connection panel. That provides it comfort usage. Special indicators allow you to control filter operation and timely change replacement filters. Also filter has a dry shutdown function.

Filter RObust 1500 is intended for purification cold water only.

RObust3000_6_1.pngOn the front panel of RObust 3000 there are two pressure gauges, one of which displays the inlet water pressure after the pre-filters, and the second displays the pressure after the pump in the membrane unit. In addition, for user convenience, the special information label shows recommended pressure values ​​for pressure gauge and recommendations for resolving possible problems if these values ​​do not correspond to those required.

Replacement filter maintenance

If the pressure after the replacement filter is less than 1 bar, this may indicate its contamination. Procrastination with the change of replacement filters can lead to damage or destruction of the membrane. The pre-filters replacement should be changed after treatment of 15000 liters of water, but at least every 3 months. The resource depends on the consumption and quality of the purified water.

Membrane element


If the filtration rate drops significantly, it is necessary to replace the RO membranes. We recommend replacing the RO membranes after purifying of 19 000 gallons of water, but at least once a year in order to obtain purified water of constant quality.   
In the case of long interruptions in the filter operation (over 2 weeks), it is necessary to disinfect the filter (the procedure is described in detail in the manual).

Carbon post filter

If the taste of purified water is significantly degraded, an unpleasant odor appears, it is recommended to replace the carbon post-filter. The post-filter should be changed after purifying of 2 100 gallons of water, but at least once every 3 months.
