CNH Industrial continually invests in energy-efficiency initiatives at all of its plants around the world. Some of these are simple modifications that produce impressive results. They include redesigning industrial processes, insulating buildings, introducing LED lighting, and retro-fitting improvements to existing equipment, among many others.
Roofs are regularly upgraded, and walls insulated to save energy. Rapid-close doors are installed wherever possible to keep heat in.
Pumps, fans and motors
Ventilation manages and helps regulate air changes on the shop floor. Aeraulic systems have been introduced in plants to check and optimize the air flow generated by pumps, fans and motors, which have also been fitted with inverters to modulate electricity use, optimizing consumption and reducing emissions.
Heating and cooling processes
Metering has been expanded across all of CNH Industrial's plants to monitor electricity consumption, and new start-up and shutdown procedures have been introduced at the start and end of the working day to help save energy when production lines are idle.
HVAC systems have been upgraded and made more efficient, and ovens such as those used during the painting process have been insulated to reduce overall energy consumption.
CNH Industrial has an ongoing program of upgrading lighting both inside and outside its plants, installing high-efficiency LED lights, presence detectors and dimmers. Wherever possible, skylights are incorporated into the roofs of buildings to exploit natural daylight, which not only helps reduce energy consumption, but also enhances the working environment.
Compressed air is used during assembly, painting and welding processes. Overall pressure has been lowered to save energy, and the air pipes are continually monitored to ensure they are in optimal condition to improve efficiency and modulation. During idle periods, heavy compressed-air machinery is shut down in favor of portable compressors.
Heat recovered from painting ovens and compressors is reintroduced into the system and used for the generation of chilled water to reduce the amount of primary energy required.
