Day Tank Systems (DTS)

The AXI 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 Tank Construction

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

Modular Design for Pump Set Configurations

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

Smart System Features & BMS Integration

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

Robust System Options & Upgrades*

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

Double Wall Tank Construction

  • All AXI International day tanks feature double wall tank construction with interstitial leak and fuel level detection for added protection against fuel leaks and tank overfills.
  • Each day tank system is manufactured to be UL-142 compliant, meeting NFPA 30 Flammable and Combustible Liquids and International Fire Codes.
  • Every system is examined and tested before shipment to confirm the tank does not display any signs of leakage and/or structural damage. These tests include hydrostatic strength, top loading, buoyancy, hydrostatic load, tank support load, and lift lug tests.

Modular Design for Pump Set Configurations

  • AXI's day tank systems offer multiple pump set configurations to meet your specific fuel transfer needs. Available pumps offer flow rates ranging from 2 GPM to 16 GPM and can be paired for redundant supply and return functionalities.
  • Pump sets are available with and without NEMA 4 rated enclosures to protect system components from elements such as windblown dust and rain. Enclosures can be upgraded to NEMA 4X stainless steel for additional protection against corrosion.

Smart System Features & BMS Integration

  • All fuel storage tanks can provide realtime feedback on tank fuel levels, pump set functionality, and system alarms.
  • Each day tank systems can support integration with existing Building Management System for remote status monitoring and external pump set shutdown capability.
  • Day tank systems without a supply or return pump set can also integrate with external fuel transfer pumps by providing crucial feedback and run signals regarding the storage tank's current fuel level.

Robust System Options & Upgrades

  • AXI's ready-use fuel storage tanks are available with options, such as a rotary hand pump, continuous level fuel detection, tank capacity readout, passive filtration, fuel filtration system, and engine supply water separation and detection. Automation controllers options are also available with LCD or touch screen interfaces, net communication capabilities, expansion modules, power supply options, and more.
  • Day tank systems can be equipped with an inline filtration and/or a fuel maintenance system to optimize the quality of fuel being supplied to equipment.
