As one of London’s premier cultural destinations, the National Gallery welcomes over five million visitors a year. Additionally about 600 staff work in the Gallery, generating an additional two thousand dryer uses per day. By installing Mitsubishi Electric Jet Towels, the National Gallery has managed to save huge amounts of energy, using only about one-tenth the energy of conventional hot air hand dryers.
Mitsubishi Electric Jet Towels produce a laminar flow of high speed air which quickly blows moisture off hands straight down into a drain. By contrast a conventional dryer generates a large volume of heated air to slowly evaporate the moisture. This requires more energy and also releases any bacteria into the atmosphere.
Housing the 2300 piece national collection of Western European paintings from the 13th to the 19th centuries, the Gallery is open 361 days a year.
