The Corcoran Gallery of Art in Washington closed a major exhibition on Wednesday because the museum's new climate control equipment was malfunctioning, causing the humidity in three galleries to fluctuate, The Washington Post reported. The show, ''Turner to Cezanne: Masterpieces From the Davies Collection, National Museum Wales,'' opened Jan. 30 and had been scheduled to run until April 25. New air handling equipment was installed as part of an $11.5 million restoration of the Corcoran's roof and skylight system, which was completed last month. (The museum previously closed for the renovation for seven weeks in early 2009.) A spokeswoman for the museum, Kristin Guiter, said the humidity levels at no point fluctuated outside the acceptable range defined in the museum's contract with the American Federation of Arts, which organized the show with the National Museum Wales. ''The art was not actually at risk,'' Ms. Guiter said, but ''we proactively opted to shut the show.'' The exhibition, of Impressionist and Post-Impressionist paintings and works on paper from the collection of two sisters, Gwendoline and Margaret Davies, had been well reviewed. Most had never been shown in the United States before. Ms. Guiter said the museum expected to replace the faulty equipment before July, when a show of Chuck Close prints is scheduled to open in the galleries. [ABSTRACT FROM PUBLISHER]
