Our Founder

A. Saadat

Mr. Anwar Saadat (Late), Founder of the Company, was a pioneer in HVACR engineering in Pakistan. Beginning his career in 1950, he earned a Gold Medal after topping the 1949 B.Sc. Honours (Engineering) examination at The Punjab College of Engineering & Technology, Lahore (now UET). He later received a British Industries Federation scholarship and completed advanced studies in HVACR Engineering in the UK, gaining international training and experience in the UK, Belgium, and the USA before returning to Pakistan.

After serving as Chief Engineer until 1962, he established his own consulting practice and went on to make significant contributions to the HVACR field. He was elected the Founder President of the Pakistan HVACR Society in 1996 and served multiple terms as Vice President of the Association of Consulting Engineers Pakistan (1990, 1995, 1997, 2001), leaving a lasting legacy in professional engineering and industry development.
