Secondary Temperature Control Circulation System

A skid-mounted, all-in-one high-temperature control system using thermal oil as the heat transfer medium. PID-controlled with ±1℃ precision and indirect cooling technology, covering a temperature range from inlet water temp +45℃ up to 350℃. Six models (3HP–15HP) with a maximum flow rate of 600L/min, engineered for everything from precision injection molding to heavy-duty die casting.

1. Imported microcomputer/PLC controller + SIEMENS & ABB electrical components for unmatched reliability
2. Auto air-venting at startup, adjustable heating power, and BY-PASS pressure relief circuit for safe, efficient operation
3. Isolated electrical control cabinet — built to withstand high ambient temperatures and extend service life
4. Optional explosion-proof configuration and RS485 communication for hazardous environments and automated production line integration
5. Comprehensive safety protection: trip, phase loss, oil shortage, overtime, overload, reverse rotation, undervoltage, with real-time fault display
