Progressive Filtration and Conditioning:
| • ||Permanent, on-site installation, indoor or outdoor for single or multipe tanks|
| • ||Multi-stage, progressive particulate filtration and water removal described below|
| • ||Integrated, high-performance 5-50 GPM pump|
| • ||Fully automated, flow control and monitoring devices|
| • || PLC based programmable digital controller|
Sizing a Filtration System:
|1. ||Coarse, straining through 40 mesh washable screens|
|2. ||Pre-filtration through 10 micron disposable media filter|
|3. ||Final filtration through 5 micron disposable media filter|
|4. ||Water separator to 15 PPM|
Most fuel contaminants will settle from still fuel resulting in a stratification of fuel with contaminants concentrated in the lower strata. Therefore, it is necessary to circulate and filter the lower 25-33% of the tank contents. The SmartFilter draws fuel from the bottom of the tank and returns the fuel with minimal disturbance of the settled strata resulting in good filtration performance and removal of contaminants and water.
It is recommended to size the SmartFilter to circulate and filter 25-33% of the tank capacity in a nominal 8-hour run period, once each week.
Below is an example for a 20,000 gallon tank:
| • ||25% of 20,000g = 5000g to circulate and filter in an 8-hour period.|
| • ||5000g/8 hours = 625 GPH or 10.4 GPM|
| • ||Use the Simplex SFG-10 SmartFilter|
| • ||For the same tank filtering 33%, or 6,600 gallons, run the SFG-10 for 11 hours or specify the SFG-20 and run for 5 hours|
There is no absolute rule. If it is desired to filter greater than 33%, or even 100% of the tank, simply specify a larger SmartFilter or run the filtration system longer. These are continuous duty devices. The only limit to run time is filter condition, which is constantly monitored by the SmartFilter controller.
