Economical Industrial RO Systems

Challenging for

The Most Economical

Commercial & Industrial RO Systems in the World !!

RA series Reverse Osmosis System

(800-6000GPD / 150-1000LPH)

PURITECH compact commercial reverse osmosis system module is a durable piece of equipment which, with proper care and maintenance will last for many years.

It is assembled with exclusive easy to operate automatic RO controller and super quiet LPE high-pressure pump which suits for most of the applications with feed water TDS below 1500

One Module

RA series RO system is capable to deliver purified water from 150 to 10,000 liters/hour for feed water TDS up 1,500 mg/l

Low Cost

Thanks to the new manufacturing facility we are able to bring the manufacturing cost down to minimum, by increasing manufacturing volume 


When you need to increase/decrease the production volume, you can simply add/remove another system module which connecting in parallel with smaller foot print


Plug and play configuration with automatic  operation that require only one button to switch ON/OFF the system. 4″ membrane module design that only require 1 person to do the maintenance

fast delivery

RA series RO system with standard modulized design allows us to deliver the product out of shelf for various project capacity requirements up to 10,000 liters/hour

We believe that industrial reverse osmosis systems are no longer to be expensive, complicated and long lead time to be produced..

RA Series RO Systems can be used FOR:


Food Service refers to the Restaurant and Hospitality Business which involves water treatment for Coffeemakers, Beverage Dispensing, Steamers, Proofers and Ice Machines among others.  In many parts of the country, the water contains significant amounts of hardness minerals – calcium and magnesium.  These hard minerals wreak havoc on the internal workings of Icemakers, coffeemakers and beverage dispensing systems, which makes lime scale one of the most costly problems in the food service industry.


Customer experience is the driving factor for success in the hospitality industry, and this is directly impacted by the quality of water used in food service or provided to hotel guests. Improving the quality of your water will upgrade your guest’s experience as they notice better tasting ice, water, coffee and vended beverages, as well as softer, brighter linens. Treated water is also a necessity to keep other amenities such as hot water, cooling towers, boilers, ice machines, and laundry services running efficiently and reliably.


Water is the most common reagent used in the laboratory, and while water quality can often be overlooked, the grade of water being used in an application is critical. Minute traces of salts or biological contaminants can result in unfortunate consequences when culturing cells or performing analytical measurements of biological macromolecules. RA series modular RO system can be used for one of the treatment process in laboratory applications with flexibility for future expansion.


It is the quality of water that puts significant impact on performance of hemodialysis system. Considering an integral part and key requirement for a successful dialysis treatment, it is necessary that hemodialysis water must follow certain standards set up by related authorities. RA reverse osmosis water systems with high salt rejection membranes that produce water following recommended standards of AAMI, FDA and ISO. 


Water treated with reverse osmosis and ion exchange systems for vehicle washes exhibits special properties – unlike normal municipal water, it doesn’t leave scale deposits on vehicles when it dries. We can provide your washing facility with the materials necessary to turn it into a spot-free wash, dramatically improving your ability to clean.


Water is essential for growth, and the quality of the water plays a key role in the health of vegetation and the yield, size, uniformity, and overall quality of crops. Well Water used for irrigation can be high in salts, minerals, nitrates, iron, and other contaminants, introducing elements to the soil which can be detrimental to growth and crop yields. If left untreated over time, the effects accumulate as the salts and contaminants left in the soil become more concentrated. Using RO treated water not only promotes high quality crops immediately, but also the longevity of the useful life of soil.


​Perfect for the small water store, water bars, juice bars, coffee & tea makers, flavored & infused water or beverage maker: Water purified by RA series RO systems has had often greater than 95% of dissolved ions, and 99% of most contaminants removed. Reverse osmosis technology is still considered the most safe and reliable method to produce drinkable water.


Process water is used in many different ways including fabrication, dilution, sanitisation or incorporation of process water into the final product. Process water is produced using a variety of technologies depending on the feed water and final water quality requirements. RO systems are very commonly used in one of the process to produce purified water.
