The Tech Inc. Reverse Electrodialysis (RED) Testing System is a membrane-based energy generation platform engineered for salinity gradient power research and blue energy harvesting. Designed in Vaughan, Canada and manufactured in Chennai, India, this system combines precision engineering with robust construction for reliable laboratory and pilot-scale performance. Tech Inc. is a Saudi Aramco approved vendor specializing in advanced membrane technology and water treatment equipment.

Overview

The RED Testing System generates electricity from salinity gradients using alternating cation exchange membranes (CEM) and anion exchange membranes (AEM). When concentrated and dilute salt solutions flow between membrane pairs, the Nernst potential drives ion transport across the membranes, generating electrical current. This technology enables harvesting of blue energy from natural salinity differences such as river water meeting seawater.

Key Features

RED stack configuration with alternating CEM/AEM ion exchange membrane pairs
Precision electrode systems (Pt/Ti or carbon-based) for efficient current collection
Configurable stack size for research flexibility (2 to 50+ cell pairs)
Power density measurement with electronic load and potentiostat integration
Digital data acquisition (DAQ) for real-time voltage, current, power, and conductivity monitoring
Independent flow control for concentrated and dilute solution streams
