Project Background

As Angola continues to advance its healthcare digitalization initiatives, a major general hospital in Luanda launched an upgrade project for its medical imaging center. As one of the region’s key healthcare institutions, the hospital has invested heavily in advanced diagnostic equipment, including Magnetic Resonance Imaging (MRI) systems, Digital Radiography (DR) equipment, and a Picture Archiving and Communication System (PACS), with the goal of improving diagnostic accuracy and patient care efficiency.

However, as these systems were deployed, the hospital recognized that its existing infrastructure could no longer meet the operational requirements of modern medical imaging equipment. MRI and X-ray systems demand highly reliable power quality, while imaging workstations, storage servers, and network infrastructure require continuous operation within a stable environmental condition. Local grid instability, including voltage fluctuations and scheduled outages, combined with conventional air-conditioning systems that could not provide precise 24/7 environmental control, created significant operational risks for both medical equipment and critical healthcare data.

To ensure long-term reliability while supporting future expansion, the hospital sought a comprehensive infrastructure solution integrating power protection, environmental control, and intelligent monitoring. GOTTOGPOWER was selected to design and deliver the complete solution.

Customer Challenges

During the initial site assessment, GOTTOGPOWER engineers conducted a detailed evaluation of the hospital’s existing infrastructure and operational requirements. It quickly became evident that the hospital’s primary concern was not simply avoiding power outages, but ensuring uninterrupted medical services under all conditions.

For MRI systems, even a brief power disturbance during a scanning procedure can interrupt examinations, require system recalibration, increase maintenance costs, and disrupt patient scheduling. Similarly, power interruptions affecting the digital X-ray system can delay diagnostic procedures and reduce operational efficiency.

At the same time, the hospital’s growing PACS platform was generating increasing volumes of medical imaging data that required secure long-term storage. Continuous server operation produces substantial heat loads, and without precise environmental management, temperature fluctuations can significantly impact the lifespan and reliability of storage and network equipment.

Furthermore, the hospital planned to expand its digital healthcare capabilities with future additions such as CT scanners, telemedicine platforms, and digital pathology systems. Therefore, the infrastructure solution needed to provide both immediate reliability and long-term scalability.

Integrated Solution by GOTTOGPOWER

To address these requirements, GOTTOGPOWER designed a comprehensive solution centered around the GT-DC5000 Micro Modular Data Center. The solution integrates UPS power protection, precision cooling, intelligent monitoring, and standardized rack systems into a unified infrastructure platform.

Compared with conventional server room construction, the GT-DC5000 Micro Modular Data Center adopts a prefabricated architecture that combines power distribution, cooling, monitoring, and IT infrastructure within a single modular framework. This approach significantly reduces deployment time while simplifying ongoing operation and maintenance.

The standardized modular design also provides sufficient capacity for future expansion, allowing the hospital to scale its IT infrastructure in line with growing healthcare demands without major facility reconstruction.

GTM060/15 Modular UPS Ensuring Continuous Medical Operations

At the core of the power protection system, GOTTOGPOWER deployed a GTM060/15 Modular Online UPS with a rated capacity of 60kVA and a backup time of 10 minutes. The UPS protects critical loads including MRI control systems, digital X-ray workstations, PACS storage servers, and core network infrastructure.

Considering the characteristics of the local power grid, the GTM060/15 utilizes true online double-conversion technology to isolate sensitive medical equipment from voltage fluctuations, frequency variations, and unexpected power interruptions. This ensures a stable and clean power supply at all times.

During the design phase, GOTTOGPOWER engineers performed detailed load calculations and coordinated the UPS configuration with the hospital’s standby diesel generator system. The 10-minute backup duration was carefully selected to provide sufficient time for generator startup and load transfer while maintaining uninterrupted operation of all critical systems.

For the hospital, this means MRI examinations can continue without interruption during utility power disturbances, imaging data remains protected from unexpected shutdowns, and critical diagnostic services remain operational even during power outages. As a result, the risk of power-related disruptions to patient care is significantly reduced.

Precision Cooling for Mission-Critical Environments

Reliable power protection alone is not sufficient to ensure long-term operational stability. Maintaining a controlled environment is equally important for healthcare IT infrastructure and medical imaging systems.

To address this requirement, the project incorporated GOTTOGPOWER precision air conditioning systems specifically designed for mission-critical applications. Operating continuously 24 hours a day, 365 days a year, the system maintains stable temperature and humidity conditions within the micro modular data center.

Unlike conventional comfort cooling systems, precision air conditioners are engineered to handle high sensible heat loads and provide accurate airflow management. This ensures optimal environmental conditions for PACS servers, network equipment, and hospital information systems.

Through optimized airflow design and effective separation of hot and cold air streams, the cooling system prevents localized hot spots and improves overall equipment reliability. This not only extends equipment lifespan but also enhances the security and availability of critical medical data.

For healthcare facilities, stable environmental control directly impacts both equipment performance and long-term data preservation. The integration of precision cooling with the micro modular data center creates an infrastructure environment that meets modern data center standards.

Intelligent Monitoring Enhances Operational Efficiency

Recognizing the limited size of the hospital’s IT operations team, GOTTOGPOWER also deployed a comprehensive intelligent monitoring platform to centralize infrastructure management.

The system continuously monitors UPS performance, battery health, temperature and humidity conditions, and precision air conditioning operation. All data is displayed through a unified visualization platform, enabling operators to monitor the entire infrastructure environment in real time.

In the event of abnormal conditions, the system automatically generates alerts and notifies responsible personnel, allowing potential issues to be identified and addressed before they develop into service-impacting failures.

This proactive maintenance approach significantly reduces the burden of manual inspections while improving overall system availability and operational efficiency.

Project Implementation and Acceptance

To minimize disruption to hospital operations, the project adopted a factory-prefabricated deployment model. The GT-DC5000 Micro Modular Data Center was fully assembled and functionally tested before shipment.

Upon arrival at the site, installation activities were limited to equipment positioning, power connections, cooling system integration, and final commissioning. This streamlined approach substantially reduced deployment time compared with conventional data center construction methods.

Following installation, GOTTOGPOWER engineers conducted comprehensive acceptance testing, including UPS transfer testing, full-load operation testing, generator integration testing, and continuous cooling performance verification. The GTM060/15 UPS successfully demonstrated seamless power continuity during utility failures, while the precision cooling system maintained stable environmental conditions under all test scenarios.

All performance indicators met the design specifications, and the project successfully passed final customer acceptance.

Project Results

Following project completion, the hospital’s medical imaging center achieved a significant improvement in infrastructure reliability and operational performance. MRI and digital X-ray systems now operate continuously without disruption from grid instability, ensuring uninterrupted diagnostic services.

The PACS platform benefits from reliable power protection and precision cooling, providing a secure and stable environment for critical medical data storage and management.

In addition, the modular architecture of the GT-DC5000 provides a flexible foundation for future expansion. As the hospital introduces new CT systems, telemedicine services, and additional digital healthcare applications, infrastructure capacity can be expanded quickly without major reconstruction.
