Installation and debugging steps and precautions for thermal oil electric heater.

Installation and commissioning steps and precautions for thermal oil heaters. 1. Preparation for thermal oil heater installation
1. Unpacking inspection: Check that the included instructions, certification documents, and accessories match the packing list.
2. Inspect the main unit, its accessories, and electrical components. If any damage or looseness is detected, promptly address it.
3. Check that the installation site meets environmental requirements and applicable conditions.
Note: Electric thermal oil heaters with an electric heating power of 100 kW or higher are considered organic heat transfer boilers and require professional installation.
2. Thermal oil heater main unit installation
The thermal oil heater should be installed horizontally and stably in a location that facilitates monitoring, operation, and maintenance. To facilitate maintenance and disassembly of the main unit heating element, sufficient space should be provided. It is recommended that valves appropriate to the operating conditions be installed on the main unit's inlet and outlet pipes (usually provided by the factory; purchase them if not available). Before installation, clean the main unit, auxiliary units, accessories, and all piping cavities to remove any accumulated water and foreign matter. 1. The piping layout for electric-heated thermal oil boilers should be low-entry, high-exit, and bends should be minimized to ensure smooth flow. The diameters of all piping in the system should be consistent with the inlet and outlet diameters of the main unit.
2. The piping of the electric-heated thermal oil boiler should be insulated to prevent unnecessary heat loss and energy waste. However, insulation materials should not be added to flange joints.
3. Connections to the electric-heated thermal oil boiler should utilize raised-face, slip-on steel pipe flanges with a nominal pressure (Pg) rating of no less than 1.0 MPa. Pipe connection gaskets may include metal-wound graphite gaskets, expanded graphite composite gaskets, or high-temperature, heat-resistant rubber asbestos sheets.
4. Install an exhaust pipe and exhaust valve at a high point in the circulation system piping network to periodically discharge gaseous products during operation. The exhaust valve should be easily accessible. When installing the pipeline of the electric heating thermal oil furnace, ensure that there is no leakage in the metal wall, welds, pipeline accessories and connection parts. If water or steam is used for pressure test, the moisture in the system must be blown out after the pressure test.
