Nowadays, containerised systems are often used in the electrical sector due to their clear cost advantages in planning, erection, installation and unbeatable mobility. The option of re-using a portable electrical solution in similar load-profile applications makes containerised electrical power and control systems a very appealing approach for consultants and end-users.
Utilizing containers as electric rooms is a method used in remote and harsh environments where deploying a complete civil and electrical project is not an option or when indoor space building space is not available.
Due to containers can be easily transported anywhere, containerized electrical solutions are likely to be installed in remote locations where permanent qualified staff is restricted due to mobilization’s cost.

DC Power Systems Into Containers
Why DC Power is Essential at Remote Locations?
Having an onsite DC Backup Power is the most reliable and cost-effective way to ensure the continuity of critical services when there is disruption of the electric power supply. Depending on the backup time, staff in charge of the site will need to assess the reason for the power outage and make a plan depending on how long the mains will be out.
Time is critical in remote applications and that is why having fully monitorable and controllable dc power systems is paramount. Helios’ hot-swappable DC Power Systems with battery backup are based on a modular design, which is easy to install and maintain. It can be configured to match the required power and capacity requirements of the client’s application.

- Communications Systems.
- Emergency Lighting.
- Fire detection and extinguish systems.
- Measurement and Monitoring units.
- Shut-off valves
- Circuit breakers operating motors.
- Arc protection device
- Temperature control
