• Start with an energy audit, then make a cooling tower efficiency-maintenance program as part of your continuous energy management program.

Diesel generator (DG) sets (also called gen-sets):

When gaps exist between the demand and supply of electric power, the role of DG sets cannot be overemphasized in order to ensure continuous processing operations in an F&B enterprise. Some best practices for saving energy in DG sets are given below:

• Regularly measure fuel consumption per kWh of generated electricity. Take corrective action in case this shows a rising trend, including preventive maintenance or replacing an old DG set with a new, efficient DG set if the payback period is attractive (under three years).

• Clean air filters regularly.

• Use waste heat from DG sets to generate steam, hot water, or power for an absorption chiller.

• Insulate exhaust pipes to reduce DG set room temperatures, especially when the

DG set shares a room with other equipment or products.

• Start with an energy audit, then make a DG set efficiency-maintenance program as part of your continuous energy management program.
