INTEGRATED HEATING SKID
Skid-Mounted Electric Heating System
Integrated Electric Heating Skid Packages for Industrial Process Applications
Xiangyuan Machinery designs and manufactures skid-mounted electric heating systems for industrial process applications that require a complete, compact and easy-to-install heating package.
Each heating skid can integrate electric heaters, control cabinets, pumps, valves, instruments, pipelines, sensors, thermal insulation, skid frame and safety interlocks into one modular unit according to process medium, heating power, temperature, pressure, site layout and control requirements.
Product Overview
A skid-mounted electric heating system is a complete process heating package built on a common skid frame. It is not only a single electric heater, but an integrated system combining heating equipment, piping, instruments, valves, control cabinet and safety protection devices.
The system can be designed for liquid heating, thermal oil heating, crude oil and heavy oil heating, chemical process heating, gas heating, pipeline heating and other industrial temperature control applications.
Compared with separately installed equipment, a skid-mounted heating system offers easier transportation, faster site installation, more compact layout, clearer piping arrangement and better factory pre-assembly before delivery.
A complete skid package can be customized with electric heater body, pump, filter, valves, pressure instruments, temperature sensors, flow switch, control cabinet, PLC / HMI, thermal insulation, skid base, lifting structure and outdoor or explosion-proof configuration when required.

The skid layout should be designed according to medium type, process flow direction, maintenance space, lifting requirement, outdoor environment, hazardous-area requirement and customer site conditions.
Materials and Customization
Material selection depends on process medium, operating temperature, working pressure, corrosion level, outdoor environment and project service requirements.
For normal water, oil or process liquid heating, carbon steel or SS304 can be used for common skid structures and heater shells. For corrosive fluids, humid environments or higher-temperature applications, SS316L, SS310S, Incoloy or selected corrosion-resistant materials can be considered.
The skid frame, piping, heater body, pump, valves, instruments, insulation and control cabinet layout can all be customized according to the process flow and site installation conditions.
Customization options include:
