ROTEK RO Controller
 Reverse Osmosis Controller C-5TM


Industrial RO System is the number one choice for industries.

The Reverse osmosis water units are specially engineered with
advanced technology. They are primarily used for eliminating
sediment and debris from the water to keep mineral deposits.

They are capable enough to eliminate near about 99.5% of dissolved
salts and other particles from the feed water with brackish and
seawater applications. Industrial RO System is the most cost-effective

solution compared to other purification processes. With extensive

research and revised with several versions, we have successfully

installed for more than 2,000 units in the field. Rotek has been designing and

supplying a standardized RO controller for the past 2 decades.

As a leading manufacturer and supplier, we offer the best yet efficient C-5TM RO controller which is intended to control and monitor the operating parameters of a single pump reverse osmosis water purification system at the most economical cost. 
C-5TM is the latest, reliable and flexible version available that can able to deal with automatic permeate flush for high brackish water applications and adjustable flush time. The manual flush button associated with can easily start and stop the flush solenoid valve whenever it requires. So a skilled engineer can flush the system with either raw water or clean water at the desired pulse rate to get the optimum result of membrane flushing during operation or CIP. 
Our Brackish Water RO System can be operated at maximum efficiency. These water units are customized for your water treatment by our expert team of application, mechanical and chemical engineers. We ensure the quality and productivity of our Brackish water RO System.
