EWS Controllers

EWS International, operating under the trade name EWS Equipment for Water Treatment Systems International B.V., originated in 1994 from the vision of two passionate engineers. Their mission was to create and produce microprocessor controllers tailored for water treatment enterprises. The design philosophy behind these controllers adhered to several key principles: ensuring compatibility with major water conditioner brands, facilitating easy programming for each controller type, and incorporating a text display with language options in at least four different languages.

EWS WATER TREATMENT CONTROLLERS


EWS water treatment controllers are advanced technological solutions meticulously crafted to optimise the monitoring and control of water softener and filtration systems, offering versatility and reliability in various installation configurations.

The ES2050 (wall-mounted) and ES2051 (panel-mounted) controllers for water softener and filters are meticulously engineered to oversee and manage both simplex (single exchange column) and duplex (twin exchange columns) water softener setups. In a simplex configuration, softened water service is unavailable during the regeneration of the exchange column. Conversely, a duplex installation ensures a continuous supply of treated water by using one column while the other undergoes regeneration.

The ES2070SV is a triplex controller for water softener and filtration and is designed to offer universal applicability, providing automatic monitoring and control for softener or filtration plants utilising solenoid valves.
