Thermon TC 202A-MR-120-C-CIRT Heat Tracing Control and Monitoring Unit

The Thermon TC 202A-MR-120-C-CIRT is a microprocessor-based control and monitoring unit designed for managing heat tracing systems in industrial environments. This dual-circuit controller provides precise temperature regulation for two independent heat tracing circuits, ensuring optimal performance in preventing freezing, maintaining process temperatures, or protecting against condensation in pipes, tanks, and instrumentation. Key features include an intuitive keypad interface, LCD display for real-time monitoring of temperature, current, and alarms, and advanced diagnostics for ground fault, high/low temperature, and sensor failures. It supports RTD inputs for accurate sensing and offers programmable setpoints, making it ideal for applications in oil and gas, chemical processing, and power generation. Advantages over similar products include robust construction for hazardous locations (Class I, Div 2 approved), energy-efficient operation reducing operational costs, and easy integration with existing systems. Drawbacks may include its discontinued status, potentially limiting spare parts availability, and the need for compatible 120V power supply. The unit analyzed appears used but in good condition with intact wiring and manual, suitable for refurbishment or direct reuse.
