The RCS5T removes chlorine, hardness, heavy metals, toxins, and a long list of other water impurities. It is engineered to meet the needs of light commercial and high demand environments, making it the optimal choice for small restaurants and small businesses. It produces reverse osmosis water at up to 500 Gal. per day, a pace that allows it to function as a tankless system without affecting functionality or convenience. The centerpiece of the system is its RO membrane that receives water from both sides of the membrane housing and is fueled by a high powered booster pump. Higher water pressure to the membrane results in faster RO production and less drain water being rejected. These factors culminate in the RCS5T achieving an exceptional 1.5:1 pure to drain water ratio. The RCS5T can be used with water pressure sources as low as 40 psi, and has a built in pressure gauge to provide an accurate pressure reading. A power source is required for the booster pump, and a holding tank can be added to the system for high usage situations. (Please Note: The RO membrane capacity is affected by the inlet water pressure and water temperature. 500GPD is the maximum rated production rate, not the recommended daily usage amount. The filter replacement schedule is based on average household water consumption of 3 Gal. per day. Filter life decreases if installed in places that require large volumes or continuous water supply).
