Jiangsu Ruiyuan recently completed the full production, quality inspection, and official delivery of a custom 2000kW hot oil heating systems for a state-owned petrochemical enterprise in Tianjin. The client operates in the acrylic acid ester and super absorbent resin sector.

This project won the bidding award last year for a new material production line. After nearly twelve months of design, manufacturing, and commissioning optimization, the equipment has now arrived at the project site. It will soon provide a stable, safe, and high-temperature heat source for the client’s chemical production processes.
Steam‑Electric Complement in Hot Oil Heating Systems for Uninterrupted Operation
This hot oil heating system integrates a thermal oil steam heat exchanger. When steam pressure fluctuates or steam temperature fails to meet the set point, the electric heating section starts automatically. It then supplements or completely replaces the steam heating to maintain a continuous heat supply to all process users.

±1°C High-Precision Temperature Control for Stable Processes
The system employs a Fujitsu temperature controller and silicon-controlled rectifier (SCR) with contactless regulation. This configuration achieves a control accuracy of ±1°C and delivers a smooth temperature curve with zero overshoot. All temperature, pressure, liquid level, and flow signals are remotely accessible via the DCS system. Consequently, operators can centralize monitoring and automate routine adjustments, which significantly reduces manual intervention.

Shielded Pump Design Ensures Safety and Reliability
The primary circulation pump uses an explosion-proof canned motor pump with a fully sealed, leak-free structure. This design suits demanding chemical environments perfectly. Moreover, the hot oil heating system features three independent interlock protection functions – low flow, over temperature, and low liquid level – that automatically cut off heating when any abnormality occurs.

Skid-Mounted Configuration for Quick Installation
The main unit adopts a frame-integrated structure with channel steel base and welded profile steel for robust load-bearing capacity. The horizontal cylindrical heater connects directly to the circulation pump piping below, including manual valves, pressure transmitters, and a pre-pump strainer. The overall layout remains compact and occupies a minimal footprint.
