Fuel Systems for Data Centers
End-to-end diesel fuel management engineered for uptime, compliance, and generator reliability.
01 / STORE
Fuel Storage & Tank Monitoring
Start with the storage system. AFS coordinates fuel tanks, catwalks, sumps, ancillary products, and monitoring to build the foundation of a reliable fuel supply.
One vendor. One service provider. A turnkey solution. Engineering, fabrication, and service work together from initial storage design through long-term operation, with nationwide support for mission-critical facilities.
- Bulk storage and tank integration
- Catwalks, sumps, access provisions, and ancillary equipment
- Tank-level gauging, leak detection, and operator visibility
Systems are designed around reliability, compliance, and operational clarity for high-availability environments.
02 / TRANSFER
Offloading, Distribution & Main-Tank Filtration
AFS designs and fabricates offloading and distribution systems specifically for data-center fuel-delivery operations. The AFS OFD-1000 connects delivery trucks to main storage, distributes fuel to generator tanks, and provides main-tank filtration through fully automated controls.
- High-flow transfer to reduce delivery time and site congestion
- 316SS piping and industrial-grade components
- Differential pressure monitoring with alarms and safety interlocks
- NEMA 4X enclosures with integrated motor starters
- Camlock™ or facility-specified quick-connect fittings
Why it matters: A coordinated delivery path helps limit contamination during transfer, maintain incoming diesel quality against ASTM D975 requirements, and reduce the risk of generator problems caused by poor-quality fuel.
03 / CONTROL
GFIP Generator Tank Controls
AFS provides engineered distribution skid solutions for multi-generator facilities, automating fuel movement from bulk storage to generator belly tanks or day tanks. AFS-manufactured GFIP panels centralize generator-tank monitoring and control.
- Automated routing based on tank levels and generator demand
- Low-low, low, high, and high-high level alarms
- Overfill prevention, alarm logic, and safety interlocks
- BMS / SCADA integration for centralized visibility
- UL-rated electrical and control-enclosure options
- Redundant pump configurations for specified N+1 requirements
Why it matters: Coordinated control supports reliable supply to each generator, reduces overfill and environmental risks, and gives operations teams clear system visibility. Designs account for applicable NFPA 30 and local authority-having-jurisdiction requirements.

04 / MAINTAIN
Permanent Fuel Quality Management
Permanent, automated AFS FFS systems maintain stored diesel through continuous or scheduled filtration, real-time monitoring, and treatment metering. Closed-loop fuel management works alongside the generator fuel-supply system to reduce contamination-related failures and support immediate startup readiness.
- Particulate and water removal to the project’s ISO 4406 cleanliness targets
- Particle counters and water sensors for real-time fuel-condition monitoring
- PLC-based automation with AFS logic programming
- NEMA 4X / UL 508 control-enclosure configurations
- Explosion-proof options for specified hazardous locations
- Telemetry and remote monitoring for operations teams
Why it matters: Proactive fuel quality management helps reduce emergency maintenance and unplanned outages while supporting ASTM D975 fuel-quality requirements and the facility’s applicable NFPA 110 standby-power maintenance program.
Supplied engineering rendering. Final configuration is project-specific.
05 / PREPARE
Fuel Line Flushing, Purging & Priming
Prepare the full fuel path before startup. AFS provides fuel-line flushing, purging, and priming as part of a coordinated commissioning plan.
- Fuel lines flushed to the project’s required procedure
- Lines purged and primed for commissioning and startup
- Work coordinated with installation and commissioning teams
This preparation connects the installed fuel-storage, offloading, distribution, and generator systems before they enter service.
06 / COMMISSION
Commissioning & Startup Services
AFS provides complete commissioning and startup services for the integrated fuel system. Equipment checks, control-sequence verification, alarm testing, and project documentation bring the installed system into coordinated operation.
- Equipment and control-sequence checks
- Tank-level alarm, interlock, and interface verification
- BMS / SCADA coordination where specified
- Startup support and project documentation
The commissioning scope is established around the installed equipment, facility requirements, and agreed startup plan.
07 / PRESERVE
Scheduled Service, Testing & Documentation
AFS provides ongoing maintenance, treatment, cleaning, and verification to support long-term fuel reliability for mission-critical data centers. Follow-up service carries the commissioning baseline into day-to-day operation.
- Routine cleaning of bulk-storage and generator tanks
- Fuel treatment for stability, microbial control, and water dispersion where indicated
- Scheduled filtration cycles based on contamination trends
- Periodic third-party laboratory testing against ASTM D975 requirements and ISO 4406 cleanliness targets
- Detailed reporting for facility records, audits, and generator-manufacturer requirements
- Emergency response services for fuel-contamination events and related generator-fuel problems
Fuel testing and facility requirements
Laboratory analysis verifies fuel properties and cleanliness. Facility service planning and records can also support applicable NFPA 30 storage-and-handling requirements, NFPA 110 emergency/standby-power maintenance requirements, and local AHJ requirements. The applicable scope is coordinated with the facility and project team.
Why it matters: A documented service program helps protect generator assets, reduce costly downtime, and support audit, insurance, and equipment-maintenance records.
