Patels Airtemp (PAT) was incorporated in 1973. It fused technical expertise with innovation to achieve a remarkable growth and an efficacious nationwide presence. The growth saga was further strengthened in 1993, when it became a limited entity and thus was born, Patels Airtemp (India) Limited.

PAT was the result of the conscious and dedicated efforts of a team of committed Engineers and Promoter - Directors. An experience of over three decades in the field of design and manufacturing was instrumental in its upbringing. Today, PAT stands proudly as one of the leading manufacturers of high quality engineering products. The success in attaining its strategic objective of nationwide presence, was made possible due to the expansion and diversification policies. The journey of the company began with a single manufacturing unit in 1973 and presently the company has two manufacturing units - both equipped with stat-of-the-art production facilities. Expansion facilitated PAT to concentrate on a much wider range of products.
