PLC Control Systems

PLC Control

We design and build PLC (programmable logic controller) systems for Reverse Osmosis equipment and water management systems. These controls are used in all Balcen standard and custom SWRO (Seawater Reverse Osmosis) systems. Our PLC systems feature industrial-grade controllers and sensors that monitor pressure, flow, temperature, water level, and water quality. These control systems are durable, reliable, and adaptable to suit the application. 

Each system is unique. Please contact us for pricing.
