SADES is a family owned business founded in 1958, in the city of Barcelona. It started off as an electrical systems supplier. One of its most emblematic projects from this initial period was the installation of the spectacular  lighting of the Expiatory Church of the Sacred Heart of Jesus in Tibidabo (Barcelona), completed in 1961.  
As Spain began to get used to air conditioning and other conveniences towards the end of the 1960s, the company's activities changed accordingly.
The installation and maintenance of air-conditioning and mechanical systems now constitute our core business.
