PORTLAND, Ore. - The Oregon Museum of Science and Industry got some new chillers to keep the air in the museum cool and installing those bad boys was quite the operation.
This all happened Monday in OMSI's Turbine Hall at the north end of the museum.
A crane was used to lift out the old chillers, which weighed about nine tons, and put new ones in.
The giant-sized project was part of the museum's Energy & Environment Initiative.
The new chillers are expected to cut OMSI's electric use by about 20 percent, a savings roughly equal to what it would take to power 120 homes for a year.
