The RCS5T removes chlorine, hardness, heavy metals, toxins, and more. It is engineered to meet the needs of light commercial and high demand environments, making it the optimal choice for small businesses. It produces reverse osmosis water at up to 500 GPD, a pace that allows it to function as a tankless system without affecting functionality. The centerpiece of the system is its dual-flow 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 dual-flow membrane results in faster RO production and less drain water being rejected. These factors culminate in the RCS5T achieving an exceptional 1:1 pure to drain water ratio. The RCS5T can be used with water pressure sources as low as 25 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.
