1. Indirect Heating:
- This method involves using a heat source located outside the ISO container to warm up the surroundings and indirectly transfer heat to the solidified cargo.
- External heaters, such as diesel-powered or electric heaters, can be used to generate warm air or hot water that is circulated around the container.
- The heat generated by these heaters is then absorbed by the container walls and transferred to the cargo, causing it to melt and liquefy.
2. Electrical Heating:
- In this method, electrical heating elements or cables are installed directly inside the ISO container.
- The heating elements are strategically positioned to ensure even distribution of heat within the container.
- By passing an electric current through the heating elements, heat is generated, which directly warms up the solidified cargo and helps it melt.
3. Hot Air Circulation:
- This method involves using fans or blowers to circulate hot air within the ISO container.
- A heat source, such as a diesel-powered heater or a heat exchanger, is used to generate hot air.
- The hot air is then circulated throughout the container using fans, ensuring uniform heating of the solidified cargo.
4. Steam Heating:
- Steam heating is another effective method for heating solidified cargo in ISO containers.
- Steam is generated externally using a boiler or a steam generator.
- Pipes or coils are installed inside the container to distribute the steam, allowing it to come into direct contact with the solidified cargo.
- The steam provides both heat and moisture, promoting melting and liquefaction of the cargo.
The specific heating method used depends on factors such as the type of cargo, its melting point, the required temperature, the availability of resources (e.g., electricity or fuel), and the safety and environmental regulations that apply. It's important to consult with experts, manufacturers, or relevant industry guidelines to determine the most suitable heating method for a particular cargo and container setup.
