Detailed Description
This shipping container has been modified from a standard ISO unit to serve as a secure, weather-resistant shelter. To achieve effective climate control, the modification process uses a one-time foaming, overall molding technique to apply the polyurethane insulation . This method ensures a continuous thermal barrier without gaps, significantly reducing temperature transfer.
The electrical system is installed to offer immediate functionality. It is configured to support lighting and power outlets, making the unit suitable for use as a field office, workshop, or secure storage for temperature-sensitive materials . Upon connection to a local power supply, the internal lighting and power points are operational .
Access is provided by a manufactured door, fitted with exposed carbon steel galvanized lock bars for security . The door hardware is designed for durability and frequent use. A drainage system, including two holes at the front and back fitted with rubber seal plugs, is incorporated into the floor design to manage internal moisture, and the aluminum floor profile facilitates easy cleaning . This unit is built for a long service life, utilizing materials selected for their resistance to corrosion and wear .
