  • Critical System Maintenance – Is My Fuel Oil Delivery System Ready for an Emergency?

 

Danbury, CT — An extremely important, but often overlooked component of the back-up generator system is the Fuel Oil Delivery system. Like a silent sentinel, the fuel oil delivery system’s mission is to supply and constantly replenish diesel fuel to the generator day tank(s). It is therefore critical to perform regular maintenance and inspections in order to ensure reliability and trouble-free operation.

The modern Automatic Fuel Oil Transfer Pump Sets, such as the Preferred Utilities Semi-Automatic Fuel Oil Transfer Pump Set, are state of the art systems which incorporate microprocessor-based controllers that monitor and control transfer pumps, return pumps, fuel tank level gauges, and tank leak detectors.

 

A typical system consists of a bulk fuel oil storage tank, duplex fuel oil transfer pump set (two 100% pumps, one for back-up) with control panel and fuel oil day tank(s).

In addition, many systems incorporate a fully automatic Fuel Oil Filtration system such as the Preferred Model PF to remove water, suspended rust, dirt and other contaminants in order to maintain the quality and purity of stored diesel fuel.
