Crystal Quest C-200 Commercial Reverse Osmosis Controller – Advanced Automation & Monitoring for Industrial RO Systems
The Crystal Quest C-200 Commercial/Industrial RO Controller is an advanced microprocessor-based control system designed to automate, monitor, and protect large-scale commercial reverse osmosis systems and industrial water treatment equipment.
Built for demanding applications, the C-200 provides centralized control of critical RO system functions including pumps, valves, storage tanks, conductivity monitoring, pressure protection, membrane flushing, and alarm management. Its flexible architecture allows system designers, operators, and engineers to customize operation for a wide range of commercial and industrial water treatment requirements.
Whether managing a manufacturing facility, food processing plant, commercial water treatment system, laboratory, healthcare facility, or high-capacity RO installation, the C-200 helps simplify system management while improving operational reliability and performance.
Complete RO System Monitoring & Control
The C-200 continuously monitors key operating parameters and automatically manages essential reverse osmosis system functions, helping reduce manual oversight and protect critical equipment.
• Feedwater supply valves — automated system startup and shutdown control
• RO and booster pumps — coordinated pump operation and protection
• Permeate and feedwater conductivity (TDS) — real-time water quality monitoring
• Membrane flush cycles — helps improve membrane longevity and performance
• Permeate divert valves — supports water quality management
• Tank level controls — manages one or multiple storage tanks automatically
• Temperature monitoring — tracks operating conditions in real time
• Pressure safety monitoring — protects equipment from abnormal operating conditions
• Pretreatment system lockout integration — helps prevent operation when pretreatment requirements are not met
Intelligent System Automation
The C-200 is designed to reduce operator workload through programmable automation features.
• Programmable setpoints and time delays — customize system operation to application requirements
• Real-time clock with battery backup — maintains scheduling during power interruptions
• Non-volatile memory storage — retains settings even during power loss
• Automatic alarm management — audible alarms with timed silence function
• Built-in RO control logic — preprogrammed reverse osmosis operating functions for faster deployment
Easy-to-Read Operator Interface
The integrated backlit LCD display provides instant visibility into system performance and operating conditions. Display information includes:
• Water quality readings
• Conductivity/TDS measurements
• Temperature data
• Alarm conditions
• System status
• Operating hours
• Diagnostic information
The intuitive 18-button keypad and dedicated alarm indicator simplify operation for maintenance personnel and facility operators.
