AXI International's Day Tank Systems are ready-use fuel storage tanks constructed to customer specifications. These systems feature double wall construction and a fire safe design, per UL-142 and UL-2085 specifications. The tanks can be configured in tandem with an open or enclosed pump set for the transferring of fuel to and from the storage tank. All tanks are designed with interstitial walls to capture leaks and will alert users of a leak and the current fill levels via the optional controller or facility integrations.

Double Wall Construction

All AXI fuel storage tanks are UL-142 compliant and feature 12-gauge steel double wall construction for an additional layer of protection against fuel leaks.

Modular Design

Each day tank comes standard with Unistrut framing to accommodate a wide variety of pump set configuration pairings for fuel supply and return capabilities.

Smart System Monitoring

Most day tanks feature smart system alarms to alert operators on system statuses. All systems feature dry contacts for external facility integrations.

Robust Upgrade Options

AXI’s day tank systems feature additional system options and upgrades to provide extra levels of passive filtration and routine maintenance of stored fuels.
