Monolec® R & O Oil significantly reduces electrical costs for Orange Water & Sewer Authority's main pump.
key takeaways
Challenge
The Orange Water & Sewer Authority ensures the tri-city area’s fresh drinking water supply by maintaining 260 miles of water main and pumping 7.5 million gallons daily, emphasizing the importance of keeping pumps in optimal condition.
LE solution
Switching to Monolec® R & O Compressor / Turbine Oil (6401) in January 1991 resulted in a 1 amp reduction in the pump’s amperage readings, improving efficiency.
Results
Monolec R & O Compressor / Turbine Oil (6401) reduces electrical energy costs by $1,599 annually using a formula that calculates savings based on volts, amperes saved, hours of operation, and the electrical rate.
Monolec R & O Compressor / Turbine Oil (6401) saves $1,599 annually in electrical energy costs.
Customer Profile
The Orange Water & Sewer Authority produces drinking water for a three-city area in and around Chapel Hill, North Carolina. They have been an LE customer since 1991.
Application
The main pump used to supply drinking water for the area is a 450 hp Westinghouse.
Challenge
In order to supply the tri-city area with fresh drinking water, the Orange Water & Sewer Authority maintains 260 miles of water main and 7.5 million gallons of water is pumped each day. It is essential that the pumps be kept in good operating condition.
LE Solution
In January of 1991, the local LE lubrication consultant recommended Monolec® R & O Compressor / Turbine Oil (6401) for this pump. Prior to converting to Monolec 6401, amperage readings were taken on the pump and measured at 81.5. After installing Monolec 6401, a 1 amp drop was achieved.
Results
The following formula is used to find the cost of a unit’s electrical consumption. This is the same formula used by the local utility company.
.Volts x Amperes Saved x 1.73* = kW Savings kW Savings x Hours of Operation Per Year = Annual kWh Savings Annual kWh Savings x Electrical Rate = Annual Electrical Savings *Conversion Factor for a 3-Phase Source
2.30 x 1 x 1.73 = 3.979 3.979 x 8,736 = 34,760.54 34,760.54 x $0.046 = $1,598.98
