Why is CHP a good technical fit for commercial dry-cleaning and laundry facilities?
- Operates at least 5 days a week, approximately 12 hours per day
- Large quantities of heat/steam consumed
- Large quantities of hot water consumed
Typical Commercial/Industrial Laundry Heat Loads:
- Tempered water (90 °F - 105 °F)
- Hot water (140 °F - 170 °F)
- Temperature dependent on laundry type
- Clothes dryers
- Steam tunnel
Current Status
There is over 4.5 MW of installed capacity in laundry facilities in the U.S. This capacity is found in six states with California and New York clear leaders. The majority of these systems utilize reciprocating engines and natural gas.
