Integrating energy-efficient cleaning processes into productionCase Study of BOSCH Diesel engines
Diesel Systems alone operates approximately 700 major facilities throughout the world. Together with our location in Homburg, the central department for production engineering, and with machine manufacturers, we have been able to develop numerous improvements which are now being considered in new purchases. Furthermore, they are being partly adopted as a standard by the manufacturers. However, retrofitting is often economical for payback periods of under two years.
Standby at the component level
An adaptation to the control software allows individual components which would otherwise always be in use to switch off when they are not needed.
The temperatures of the cleaning media can be significantly lowered through practical experiments without altering the chemistry or the cleanliness of the products.
Isolating the containers, filters and pipes minimises heat loss.
Larger pumps are especially used for high-pressure cleaning. The pressure is often constantly maintained by a lossy bypass regulator. The new regulation of the pump speed provides significant savings.
The retrofitting process in Homburg is almost completed and there has been average energy savings of 25%. In some cases, this can be up to 340 MWh per machine. Altogether, the location has reduced its consumption by over 8,000 MWh per year. We kicked off our global rollout in mid-2012, and to this point we have been able to account for total savings of about 21,000 MWh per year. This is equivalent to the electricity needs of 5,250 single-family houses.
