We are a leading company in the watertreatment microprocessor manufacturing industry. Our products are devices specially designed for the watertreatment industry. For a cooling tower system we introduce new watertreatment controllers: CTS 8000 Visit E.W.S's products for watertreatment controllers page E.W.S. introduces the new UFS8000 ultra filtration watertreatment controllers


This is a reverse osmosis controller

RGS8000 a reverse osmosis controller


The unit type RGS8000 is universal applicable for automatic monitoring and control of reverse osmosis plants. There are six possible stages : "Stand by", "Production", "Rinse after production", "Rinse during production", "Rinse during standby" and "Maintenance ". This unit can monitor conductivity, temperature and several inputs e.g. level switches, low pressure switch, motor security switch, etc.. Adaptable to user specific requirements by built-in programmable options. The programmed configuration will be stored into non volatile memory and therefore not be affected by power loss.
