The Westerscheldetunnel, a vital infrastructure asset managed by N.V. Westerscheldetunnel on behalf of the Province of Zeeland, is the longest tunnel in the Netherlands at 6.6 kilometres underwater.
As a key transportation route, the tunnel ensures smooth connectivity between regions, making its uninterrupted operation critical. A power outage in such an environment could jeopardize the safety of travelers by disrupting critical systems, such as lighting, ventilation, and signaling. Ensuring these systems remain operational, even during power disruptions, is essential to safeguard the lives of those driving through the tunnel.
Delta addressed this vital need by installing state-of-the-art IPT-50kVA Industrial Power Transformer-based UPS systems, showcasing its expertise in delivering comprehensive turnkey solutions for industrial environments.
Innovative Tailored Power Solutions
The UPS system previously used in the Westerscheldetunnel had reached the end of its lifespan and needed to be replaced. The complex logistics of installing a new system within the tunnel presented significant challenges. To address these issues, a solution was needed that could ensure reliable power delivery while optimizing space and operational efficiency.
To meet these requirements, Delta supplied its newly launched IPT-50kVA UPS units, each with a compact footprint (600 x 830 x 1420 mm), making them ideal for installations where space is limited. These systems feature advanced technologies, including IGBT rectifiers for low total harmonic distortion (iTHD <3%) and inverter-integrated isolation transformers, enhancing short-circuit capability and load separation. These innovations provided a reliable and manageable power solution that directly addressed the tunnel’s requirements.
Efficient Implementation in a Record Time Frame
In December 2023, Croonwolter&dros, acting on behalf of N.V. Westerscheldetunnel, partnered with e-Power to implement Delta’s IPT-50kVA systems during the second phase of the project. Delta’s product management and engineering teams collaborated closely with e-Power to deliver the UPS systems on a tight schedule, meeting the demanding deadline.
The new systems have significantly enhanced the tunnel’s operational efficiency. Features such as a user-friendly 10-inch waterproof touch panel and advanced event analysis capabilities have reduced maintenance time and costs. Additionally, the compact design also streamlined installation, optimizing project and labour management.
Ensuring Safety Through Reliable Power
The reliability of the IPT-50kVA UPS systems plays a critical role in ensuring safety within the Westerscheldetunnel. These systems provide seamless backup power, ensuring that essential functions like signaling, ventilation, and lighting remain operational even during power outages. Such redundancy is vital to maintain visibility, air quality, and clear communication within the tunnel, preventing accidents and ensuring the safety of the traffic going through the tunnel.
Mr. Leon van der Kraan, Procurement Manager at Croonwolter&dros, remarked: “The collaboration between Delta, e-Power, and Croonwolter&dros has been vital in the successful upgrade of the Westerscheldetunnel’s power infrastructure. Delta’s innovative IPT-50kVA UPS systems have met our stringent requirements, ensuring reliable and efficient tunnel operations that prioritize the traffics safety.”
Overcoming Challenges with Strategic Collaboration
Delta’s partnership with e-Power ensured efficient handling of logistics, installation, commissioning, and ongoing service, adhering to Croonwolter&dros’ high standards for reliability and performance. This collaboration effectively addressed logistical challenges, including extended sea freight times from Delta’s overseas factory to Europe.
Mandy Ho, Sales Manager, Data Center Segment, Delta EMEA, added: “Our IPT-50kVA systems’ compact footprint and robust features provided the perfect solution for N.V. Westerscheldetunnel’s needs. The successful delivery and installation by our premium partner e-Power further cement Delta’s position as a leading provider of containerized data center solutions.”
Arnoud Blijleven, Technical Director at e-Power, emphasized: “The innovative IPT-50kVA systems have exceeded our expectations in terms of performance and reliability. This project exemplifies the strength of our partnership and our combined ability to deliver outstanding solutions for critical infrastructure.”
A Successful Partnership and Future Prospects
The Westerscheldetunnel project marks the first successful implementation of Delta’s IPT UPS solutions in the Netherlands. Delta’s proven track record, supported by dependable partnerships with Croonwolter&dros and e-Power, has positioned Delta as a leading provider of UPS systems in critical infrastructure. This project highlights Delta’s and its partners’ ability to deliver high-quality, turnkey solutions that meet stringent requirements. Delta looks forward to leveraging this success in future projects, applying the valuable experience gained to continue offering innovative and reliable solutions to its clients.
