The Empress ST-200 reverse osmosis system is designed for light commercial applications. It features a coated steel frame that can be either wall-mounted or used as a free-standing unit. It produces 200 gallons of water per day. Therefore, it is a suitable choice for light-use food service and commercial applications such as coffee shops, restaurants, cafeterias, catering operations, and offices.
The ST-200 demonstrates superior removal performance for chlorine, hardness, heavy metals, toxins, and other water impurities. A built-in booster diaphragm pump enhances water production by increasing water pressure to the optimal level for the reverse osmosis process.
