The STS-6000 removes water, sludge and prevents tank sediments in stored fuel.

Fuel is inherently unstable. It naturally forms sediments, solids and tank sludge. Clogged filters, smoke and damage to injection systems are often symptoms of less than optimal fuel quality causing engines to be unreliable, smoke, lose power and ultimately fail. Water naturally accumulates in storage tanks due to condensation or leaks in fills and vents. Water and temperature changes create an environment for microbial growth and natural oxidation, accelerating formation of sludge, acids and tank corrosion.

The STS 6000 Fuel Filtration Systems are self contained, stand-alone and fully automated. They recondition and stabilize fuel, eliminate & prevent microbial contamination and remove water, sludge and contaminants from tanks; preserving the integrity of stored fuel, providing reliable power whenever it is needed.

STS Installation

Implementing STS Fuel Maintenance Systems assures Optimal Fuel Quality & Reliable Engine Performance at all times. It prevents costly downtime, periodic tank cleaning, replacing out of spec fuel and injection system repairs.

The principal components are a continuous duty motor with coupled gear pump, strainer/primary filter with vacuum sensor & gauge, Algae-X Fuel Conditioner, and a secondary filter with pressure gauge & sensor. The system is automatically operated by the programmable, UL 508A listed Algae-X Smart Filtration Controller. All components and control devices are contained within a fully enclosed, lockable, weatherproof NEMA 3R cabinet.

The strainer/primary filter protects the pump and removes water and particulate. The secondary filter is a quick change spin-on filter designed to remove emulsified water and contaminants down to 3 Micron.

For safe operation the STS 6000 is equipped with a drip tray monitored by a leak detector. Additional safety elements include automatic system shut-down and indicators when filter elements require service, high pump vacuum exists or a flow interruption is detected.

STS 6000 Accessories: AFC-705 Fuel Catalyst, Wide range of filter elements, Rotor Sight Glass, Foot Valve, Separ Primary Filter, Two tank control, Digital flow meter.

Fuel Maintenance is an important part of periodic generator maintenance programs – just like changing the oil and ensuring the batteries are charged.
