Aprilaire Central Dehumidifier & Steam Humidifier Help Preserve Maryland’s first synagogue



 

The challenge for John Lederer, principal owner of Frosty Refrigeration, Inc. in Baltimore, Maryland, was to control the level of humidity in the museum of the nation’s 3rd oldest remaining synagogue. Built in 1845, the Loyd Street Synagogue museum is located in the lower level of the Greek Revival structure. Humidity control was required to help preserve the historical artifacts, exhibits as well as the structure itself. Adding to the challenge was the requirement to maintain a constant humidity level of 40% to 50% all year round, to “...a historical building, not weatherized and with high infiltration.” With the help of Aprilaire’s Partner Website, John was able to calculate how much moisture would be required to add during the heating season and removed during non-heating seasons. “ The Aprilaire website software was helpful and intuitive.” Since there was no existing forced air duct system in the museum area, Frosty Refrigeration designed a stand alone system that included: an Aprilaire 1770A Central Dehumidifier; model 1160 Steam Humidifier; and a forced air system with duct work and dedicated blower. A commercial humidistat was used with high and low limits to control the 1160 and 1170A operation.   According John, “... the designed system and Aprilaire equipment have outperformed expectations.”
