Belly tanks are specialized fuel storage tanks designed to supply emergency power generators in data centres. These tanks ensure uninterrupted operations during power outages by providing reliable backup fuel capacity. Belly tanks can be engineered to support the weight of a generator or container and may also be installed adjacent to the unit for flexible placement. In addition to rectangular belly tanks, CGH Group also manufactures cylindrical fuel tanks.

Why Belly Tanks Are Essential for Data Centres
