The pre-equipped high powered booster pump maximizes RO production by increasing water pressure going into the membrane.

The 500 GPD membrane offering an exceptional 1.5:1 drain ratio.

The RCS5T produces RO water on demand, eliminating the need for a water storage tank.

how does it work

Overview

The RCS5T 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 gallons per day, a pace that allows it to function as a tankless system without affecting functionality or convenience. The centerpiece of the system a RO membrane 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.

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 gallons/day.
  • Filter life decreases if installed in places that require large volumes or continuous water supply.

Common Uses

r1

o

r

The RCS5T's ability to thrive without a tank make it a great space conservation option which also meets the daily demand of most households. Add a smallest pressurized tank to increase the flow without wasting cabinet space.

A healthy office is a happy office. Keep your employees well hydrated with all the RO water they can drink. Adding a small pressurized tank ensures a continuous and stable supply of pure water without delay.

(Good for small offices with under 20 people)

Food or drink that is prepared with unpurified water may have a distinct, unpleasant taste. A reverse osmosis system ensures that the water used to boil pasta, make coffee, or quench the thirst of your customers tastes clean and fresh. Pair the system with a medium sized pressurized tank for a steady supply of pure water to keep up with the demands of high water consumption.

(Good for small sized restaurants with under 20 seats)

Product Description

The iSpring RCS5T is a high capacity tankless reverse osmosis purification system. The RCS5T's high-efficient RO membrane produces RO water at a rate of 500 gallons per day while delivering a top-of-the-line 1.5:1 pure to drain ratio. The system removes chlorine, hardness, heavy metals, toxins, and a long list of other water impurities. The on demand output ability makes the RCS5T a great choice for large families or light commercial use in small restaurants, beauty salons, offices, coffee Shops, or any small business. Why iSpring? Located in Alpharetta, Georgia for over a decade, iSpring Water Systems LLC is a family owned company specializing in reverse osmosis water filtration systems. Our products include residential and commercial Reverse Osmosis (RO) systems, whole house water systems, ultra-filtration systems, shower, faucet, and counter top filters, filter cartridges and housings, RO coolers, and kitchen faucets and fittings. Our aim is to make high quality drinking water accessible for all households. With affordable pricing, solid quality, prompt delivery, and top notch customer service, we hope to assist in bringing you great water for years to come. Incoming Water Pressure: 40 PSI - 70 PSI Operating water temperature range: 40 – 100 °F Maximum TDS: 750 ppm Membrane Filter Life: 2-3 years at 3 Gallons/day or 2600 Gallons Note: All flow rates stated on our reverse osmosis systems and membranes are assuming a water temperature of 77°F. Water temperature changes will affect the flow rate. For every degree F the temperature lowers, about 3% of product flow is lost. For every degree F the temperature increases, about 3% product flow rate is gained. This occurs because water with a higher temperature has a lower viscosity and higher diffusion rate, which makes it easier for the water to permeate the RO membrane. Lower feed water temperatures during the winter season will result in a decrease in flow rate.

Customers are mixed about the water quality of the water purification unit. Some mention that the quality is spot on, and the waste water is doing great with plants.

This produces 500 gallons of RO water per day
Our company is a supplier of roasted and unroasted coffee. We also produce Cold brew products. When we began to produce cold brew our demand was sufficeint to use the first system we bought from iSpring which was RCC7AK.This system worked well until we were producing more product than it would hanle. It is rated at 75 gallons per day which is 3 gallons per hour.After much research we spoke with Michele at iSpring. We traded email several times and had a few conversation about our issue. She made a suggestion to upgrade to the RCS5T which produces 500 gallons per day at 20 gallons per hour which will satisfy our needs.We also upgrade our holding tank from 3 gallons to 20 gallons. With the RCS5T system it has a pump and if dont have a high demand you dont need a tank.I emailed Michele once again before we made the purchase and instead of eamiling me back, she called me and answered the questions I had about the flavour of our water that is important for coffee. She was kind enough to provide us with an alkaline cartridge to our purchase which provides that extra element we needed to give us the excellent water flavor we need for our product.After installation, we have been elated with the performance and the quanity of water it produces for us.iSpring provided us with great support and with Michele's help and speedy replies we conquered our water and supply issue.Many Thanks!Martini Coffee Roasters
