In October 2025, Comler Power entered into a key cooperation with CCCC Fourth Harbor Engineering Co., Ltd. First Engineering Company, supplying one 800kW diesel generator set for the Zanzibar New Port Project. This not only demonstrates the exceptional adaptability of Comler's diesel generators to harsh environments but also embodies the deepening cooperative spirit and profound friendship among Chinese enterprises in advancing global infrastructure development.
Zanzibar features a tropical maritime climate with year-round damp heat, an average temperature of 26°C, high humidity, and coastal salt spray, posing severe challenges to mechanical equipment reliability. Comler's 800kW diesel generator set was custom-developed for the region's unique needs, integrating multiple core technologies to overcome environmental hurdles:
Corrosion & Climate Resistance: Adopting IP56 protection rating and a three-layer anti-rust coating system, it passed 480-hour salt spray testing without corrosion. The water-air dual-circulation cooling system ensures continuous full-load operation at 45°C for 120 hours, with exhaust temperature 15°C lower than national standards, perfectly adapting to Zanzibar's persistent high temperatures.
Stable Power Output: Equipped with the world-renowned Cummins WP17 engine and Stanford generator, the voltage fluctuation is ≤±1%, delivering stable and reliable power. This feature is crucial for port construction equipment such as excavators and pile drivers, avoiding project delays caused by power outages.
Tanzania has long faced power shortages, driving sustained growth in the diesel generator market. Over the past three years, the power gap has continued to expand. Zanzibar's power grid coverage is less than 35% with unstable supply during dry seasons, and the infrastructure boom has spurred strong demand for high-power diesel generators. Cheap imported equipment frequently fails due to inability to withstand the tropical maritime climate and non-compliance with new regulations, resulting in a significant shortage of compliant, high-quality units. High-power models above 375kVA have become the core of market growth with a CAGR exceeding 3.6%.
CCCC Fourth Harbor Engineering's selection of Comler's equipment reflects not only trust in product quality but also a shared commitment to advancing China-Tanzania cooperation. For decades, CCCC has been a cornerstone of Tanzania's infrastructure development, leaving numerous cooperation footprints from the renovation of Dar es Salaam Port (a benchmark Belt and Road project) to the under-construction Magufuli Bridge. This cooperation continues this fine tradition:
Synergy of "Chinese Quality": Just as CCCC introduced Chinese standards such as PHC pipe piles to Tanzania's port construction, Comler's generator sets bring the advantages of Chinese manufacturing to the region. We ensured smooth logistics throughout the process, from the factory directly to Guangzhou Nansha Port and then to Zanzibar, accurately meeting the project's tight schedule.
Beyond Business: Jointly Building a Development Vision: Once completed, the Zanzibar New Port will create local jobs, drive port-side industrial development, and enhance regional connectivity, practicing the mutually beneficial cooperation concept of the Belt and Road. Comler's after-sales team provided on-site training for local technicians, imparting maintenance skills to support the long-term stable operation of the project.
As the Zanzibar New Port gradually becomes an important maritime hub in East Africa, the Comler 800kW diesel generator set stands as a vivid symbol of reliable cooperation. This partnership with CCCC Fourth Harbor Engineering not only demonstrates Comler's commitment to empowering global infrastructure projects with customized, high-performance power solutions but also continuously nurtures the profound bonds of international friendship through joint progress.
