ABB frequency converters

Did you know… 
...ABB frequency converters are helping preserve interiors and precious artwork at the historic State Hermitage Museum in the cultural capital of Russia? 

The world’s second-largest art museum, the State Hermitage Museum in Saint Petersburg, Russia, houses more than three million works of art and world culture artifacts, including paintings and sculptures. Maintaining strict microclimate parameters for temperature and humidity while constantly keeping air exchange and filtration going are essential in preserving the museum’s historic interiors and precious art. Good ventilation is equally important for providing a comfortable environment for visitors and museum workers.

The HVAC (heating, ventilation, and air conditioning) control systems in the vast Coat of Arms Hall of the Winter Palace are equipped with ABB frequency converters. The ACS880 drives were introduced into the museum in 2014, when they were just launched in Russia, to optimize ventilation in the museum halls as well as decrease energy consumption by using variable speed control process. As a result, energy costs reduced up to $12,000 annually and carbon dioxide emissions reduced by 78 tons, which is equivalent to greenhouse gas emissions from an average passenger vehicle driving more than 175,000 miles/280,000 kms.

Key facts:
  • Annual CO2 emissions reduced by 78 tons
  • Energy costs reduced up to $12,000 a year
  • Museum attracts over 5 million visitors each year
