Fuel marketers and fleet fueling owners often need to store different grades and types of fuel in a single location. ZCL | Xerxes multicompartment fiberglass tanks, compatible with petroleum, diesel and new biofuels, offer a wide range of fuel storage possibilities in a single, compact installation.

Other benefits start the moment the tank leaves the manufacturing facility. Shipping and installing a multicompartment tank rather than several tanks often saves space and money. Insurance and permitting costs may also be reduced. Our multicompartment tank comes standard with a double-wall fiberglass bulkhead and eliminates the added cost of upgrading to a double-wall bulkhead often required with steel tanks.
