The Simplex SmartFilter 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 underground and aboveground main supply tanks, large generator sub-base tanks and large day tanks. Typical tank capacities are in excess of 5000 gallons, with 10,000-20,000 gallon or larger tanks being common. The SmartFilter system provides typical 8-hour filtration rates to cycle 25%- 33% of tank capacity on a weekly basis. Principal uses of the SmartFilter are with fuel tanks dedicated to diesel or turbine engine generator sets or with oil-fired boiler or process heat systems.
The SmartFilter 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. Many studies have indicated poor fuel quality as a major cause of dispatch failure of 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. Given water and a source of oxygen, microbes “feed” on the constituents of fuel, namely carbon, nitrogen, phosphorous, sulfur and other trace minerals. Persistent water contamination of fuel oil will allow for the proliferation of these microbes. Not only is the chemical makeup of the fuel being attacked, these microbes deposit contaminants which can clog engine filters, or worse, injectors. Unscheduled downtime is the result.
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 long-term 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.Keep in mind a simple fact. There are 8760 hours in a year. A typical standby generator set may run less than 300 hours a year. During the remaining 8500 hours of engine “quiet-time”, microbes and corrosion continue their work of degrading fuel. The SmartFilter attacks and corrects these sources of fuel degradation. The SmartFilter thus becomes a critical element in the chain of reliability of standby power systems.
The SmartFilter combines several elements to form a comprehensive, integrated, automated system:
• Multi-stage, progressive particulate filtration and water removal
• Integrated, high-performance pump
• Flow control and monitoring devices
• Digital, user-programmable controller
The SmartFilter uses a progressive filtration and conditioning regime:
1. Coarse straining through 100 mesh washable screens
2. Pre-filtration through 10 micron disposable media filter
3. Final filtration through 2 micron disposable media filter
4. Water coalescing to 5 PPM
5. Water separation and collection
Fuel circulation and transfer is accomplished via an on-board, high-performance, cast-iron, 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 industrial type, conservatively applied and include ball-bearings, class H insulation and continuous duty ratings.
The SmartFilter system includes shutoff ball valves, check valves, flow switches, pressure and differential pressure gauges, and differential pressure sensors across each filtration element. Single or multi-tank valving is available.
