Various kinds of equipment used to transform or process material or to assist in another job are important to control.

Process Equipment Savings

• If practical, turn off equipment when it is not in use.
• Use to load capacity.
• Replace old equipment. Older office equipment and process machinery uses motors and control systems that are substantially less energy-efficient than current models.
• Chiller systems use significant energy. Determine whether the system is required on cooler days. Shut down for periods of time when weather permits to reduce energy cost.

Air compressors

• For every two psi reduction in pressure, there is a potential one percent energy savings.
• Receiver tanks allow a volume of air to be stored, reducing the operating time of the compressor. Locate the tanks near equipment requiring the largest volume.
• Consider using an air dryer. Condensation in the air system leads to equipment operation problems and maintenance issues, yet opening the traps to blow off condensation adds substantially to the cost of energy.
• If multiple air dryers are used, determine the air quality required and shut down excess dryer capacity to control energy costs.
• Turn off when not in use.
