STS 7020 Fuel Maintenance System

STS 7020 Fuel Maintenance System

The STS 7020 is a programmable, fully automated, fuel maintenance system that removes water, sludge, and other contaminants from fuel storage tanks through routine filtration. The system’s NEMA 4 rated enclosure allows for both outdoor and indoor installations by protecting the system from windblown dust and rain, hose directed water, and ice formations. With a 20 GPM flow rate, the STS 7020 can polish up to 9,600 gallons (36,340 liters) of fuel in a runtime of 8-hours. Robust system upgrades are available for this system and can be found under the “System Upgrades” tab below.
