ONSITE+ Onsite+ is a polishing water purification system, for which the feed water must be pre-treated by reverse osmosis or distillation. System contains an embedded tank that has to be filled with pre-treated water before operation. Onsite+ series systems are recommended for laboratories with average daily consumption of water within 5-10 litres.
