Ecosoft Robust 4000 reverse osmosis – industrial reverse osmosis for hospitality businesses

The Ecosoft Robust 4000 reverse osmosis system is an ultra-compact industrial unit for water preparation in hospitality, for example for dishwashers in restaurants and other food-service businesses. It works with direct flow, and the stainless steel housing matches other hospitality equipment. The flow is 150–180 L/h, and the unit is rated for up to 20 hours of continuous operation per day. According to the manufacturer it is CE marked and meets current EU directives.

Reverse osmosis purifies water through membranes and reduces the content of dissolved substances, so the water suits dishwashers, where it helps prevent spots and limescale. According to the manufacturer, the Ecosoft Robust 4000 reverse osmosis system also suits small breweries and laboratories and removes up to 98 % of contaminants, including suspended solids, bacteria and viruses. The page cites no test standard.
