International brand dossier

EWS

EWS International is a water-treatment controller specialist whose public site positions the company in microprocessor-based controllers for industrial water treatment.In this catalog it is relevant where softening, filtration, dosing, conductivity, or plant control logic requires dedicated controllers rather than only standalone sensors.

EWS's position in instrumentation and sensors is defined by product families such as Controllers for Reverse Osmosis, Controllers for Ultrafiltration, Controllers for Filters and softeners and Controller for Demineralisation.

The portfolio is best understood inside online water-quality measurement, process control, chemical dosing feedback, plant monitoring, and safety interlocks, where engineers compare the technology route, family boundaries, and duty fit before narrowing to individual models.Representative series on this page include OS3015, OS3020 and OS3030.Engineers should compare measured parameter, range and accuracy, wetted materials, calibration workflow, and control-system communication.

Product range and selection

How to choose EWS Instrumentation & Sensors

This section answers two questions: which main product families EWS offers, and which parameters to compare before choosing a specific model.

Step 1: Choose a product family by application

The main families shown on this page are Controllers for Reverse Osmosis, Controllers for Ultrafiltration, Controllers for Filters and softeners, and Controller for Demineralisation. Start with the treatment objective, equipment format, and operating duty, then use the model index below to compare exact specifications.

Step 2: Confirm the model by key parameters

After choosing a product family, compare measurement parameter, sample condition, signal integration, and maintenance frequency. Replacement projects should also verify installation or loading conditions, interfaces, and compatibility with the existing system; new projects should consider operating practice, maintenance, and spare-parts or consumables availability.
