Catalog 13: Carrier air washers and humidifiers: applied to public office and industrial buildings, with notes on humidity
A 1913 trade catalogue issued by the Carrier Air Conditioning Company of America, printed by its own publisher, presenting its air washers and humidifiers for public office and industrial buildings with notes on humidity. The photographs show installed equipment in plant rooms, with pipework, valves and cabinets photographed at close range, so a designer might take from them the dense, utilitarian geometry of mid-century mechanical plant spaces, with strong verticals, repeated pipe runs and grey tonal contrast.
