Kalyani Thermal Systems Ltd. (KTSL). (Formerly Pune Furnaces and Equipments Co. Pvt. Ltd) was established in 1979. KTSL was set up to help the steel, forging and metal working industries; to meet the challenges posed by energy crisis and spiraling energy costs. The objective was to put state -of -the-art technology to work for the benefit of our customers.

KTSL's involvement in the project begins from the very first stage when a client begins planning for a new industrial furnace installation. We then put our designing skills to optimal use to manufacture a product, best suited to the client's customized requirement.

On 22nd April, 1993, KTSL joined hands with Flinn and Dreffein Engineering Co., U.S.A. to become a part of world's industrial furnace manufacturing group. Through this venture we introduced advanced thermal technology in India.

Over the years the company has been catering to the auto component business. But the main focus of the company was ENGINEERING & FURNACE related. In the year 2001, the auto components business was brought into focus, and ever since the company has grown its auto component business from 600 tons per year to 10,000 tons per year.

The major landmarks have been ISO 9001:2000 accreditation by UL, INDIA in 2001 and TS - 16949 accreditation by UL, INDIA in 2005.
