Technical Specifications

Working Principle

The system operates through two completely independent thermal oil circuits, each with dedicated heating elements, temperature sensors, and control systems. This parallel configuration allows either circuit to maintain process temperature independently, ensuring continuous operation during maintenance, cleaning, or unexpected component failure. The PLC-controlled system manages both circuits simultaneously while providing independent regulation and monitoring.
