AXI International’s STS products are programmable, fully automated, fuel maintenance systems that remove water, sludge, and other contaminants from fuel storage tanks. Once installed, the STS systems work autonomously to ensure fuel reliability through scheduled routine filtration. The system’s fuel polishing process stabilizes diesel and bio-fuels, eliminates microbial contamination, and ensures fuel remains contamination free. These enclosed fuel maintenance systems feature NEMA 4 rated enclosures which are specifically designed for permanent installations either indoor or outdoor to service both Above Ground Storage Tanks (AST) and Underground Storage Tanks (UST).

Schedule Automated Fuel Polishing Runs

All STS fuel maintenance systems are fully automated and can be programmed with a weekly routine for the polishing/filtration of the attached tank and fuel supply.

NEMA Rated System Enclosure

Each STS system is constructed inside a standard powder coated NEMA 4 rated cabinet featuring a drip basin with leak detection to alert users in the unlikely event of a fuel leak.

Smart System Alarms & BMS Integration

All STS systems feature smart system alarms giving users insight on system statuses. Each system also features field connections for remote monitoring and shutdown.

Robust System Options & Upgrades

All 7000 series STS systems have robust system upgrade options to reduce maintenance intervals, increase ease of use, and expand system servicing capabilities.

Simply select the days you want your system to filter the fuel and enter up to three start and stop times per day.

NEMA Rated System Enclosures

Ensure your system's components are protected from the elements such as windblown dust and rain with NEMA 4 rated enclosures. For extreme environments, upgrade to NEMA 4X rated Stainless Steel enclosures for additional protection against corrosion.
Prevent any unnecessary ground contamination during routine system maintenance with a built in drip basin designed to collect any excess fluids.
Be alerted in the unlikely case of a system leak with a leak detection float sensor mounted to the back of the system's drip basin.

Smart System Alarms & BMS Integration

Get realtime feedback on system statuses via the system's alarms and feedback modules. Know when it is time to change filters and be notified of system errors right as they occur.
Integrate your STS fuel maintenance system into your building management system (BMS) for remote monitoring of system statuses and remote system shutdown capabilities.

Robust System Options & Upgrades

All 7000 Series STS systems feature an intuitive touchscreen controller that expands the system's capability for system upgrades.
