Why FuelVu

Indefinite Fuel Oil Validated with On-line Testing

No other system on the market addresses the primary reason for back-up power failure making FuelVu a timely asset to your facilities emergency back-up power management plan.

The FuelVu Series comprises a standard, engineered-design family of fuel oil filtration, conditioning and maintenance systems. These systems are intended for use with fuel oil held in bulk, long-term storage, including aboveground main supply tanks, large generator sub-base tanks and large day tanks. Typical tank capacities up to 13,400 gallons. The FuelVu system provides typical 8-hour filtration rates to cycle 25%- 33% of tank capacity on a weekly basis. Principal uses of the FuelVu are with fuel tanks dedicated to diesel or turbine engine generator sets, oil-fired boiler and process heat systems.

The FuelVu Series is especially relevant and timely when considering the stringent fuel quality requirements of modern industrial engines where fuel quality impacts engine performance, reliability and emissions. Studies have indicated poor fuel quality as a major cause of dispatch failure with standby power systems. Fuel in long-term storage is subject to degradation from bacteria, fungi, yeast, mold and algae. Ironically, fuel oil is a favorable medium for the growth of these microorganisms. Not only is the chemical makeup of the fuel being attacked, these microbes deposit contaminants which can clog engine filters, damage, injectors, unscheduled downtime and worse generator failure during emergency power failure.

Where does this water originate? Uncertain quality of fuel deliveries is one source. However, simple atmospheric condensation and the resultant accumulation of water in a vented tank certainly represents the source of longterm and persistent water in fuel.

Particulate contamination is a significant source of fuel oil degradation as well and can occur in long-term storage due to tank corrosion or from contaminants accumulating over the course of many deliveries.

A typical standby generator may run less than 300 hours a year. During the remaining 8500 hours of engine “quiet-time”, microbes and corrosion continue the degrading fuel. FuelVu attacks and corrects these sources of fuel degradation thus becoming a critical element in the reliability of standby power systems. FuelVu combines several elements to form a comprehensive, integrated, automated system:

  • Multi-stage, progressive particulate filtration and water removal.
  • Integrated, high-performance pump.
  • Monitoring devices and alarms.
  • Digital, user-programmable controller.
  • Particle Counter to monitor for fuel compliance within the ISO 4406 cleanliness code. This particle counter samples and communicates that the filtered fuel meets the recommended world wide fuel charter to attain the desired 18/16/13 ISO Code for 4, 6 and 14 micron particle sizes. This alerts if stored fuel requires longer or more aggressive filtering to bring the fuel into compliance.

FuelVu uses a progressive filtration and conditioning regime:

1. Coarse straining through 40 mesh washable screens.

2. Final filtration through 5 micron disposable media filter.

3. Water coalescing to 15 PPM.

4. Water separation and collection.

Fuel circulation and transfer is accomplished via an on-board, high performance, cast-aluminum, positive displacement gear pump direct-driven via an industrial, heavy-duty motor. The pump combines high vacuum prime maintenance with linear flow versus pressure performance. An integral pressure relief valve is included. Drive motors are NEMA class industrial type, conservatively applied and include ball-bearings, class H insulation and continuous duty ratings.

The FuelVu system includes shutoff ball valves, check valves, pressure and differential pressure gauges, and differential pressure sensors across the filtration element.

Intelligent automation and operator interface is the hallmark of FuelVu. Each FuelVu is packaged with a digital controller. This UL508A listed and labeled industrial control panel features PLC-based digital control and touch-panel operator interface. The controller provides full automatic operation of the system and is operator field programmable to set filtration cycle duration, time of day, day of week operation. Manual override capability is included. The controller monitors differential pressure across the filtration element and water level in the separator collection vessel. Operational alarms are likewise generated. The controller is MODBUS or Ethernet network compatible for integration with remote Building Automation Systems or generator control switchgear.
