TANFAC Industries, an Indian chemical company, has successfully commissioned its 5,000 tonnes per annum (TPA) Solar Grade Dilute Hydrofluoric Acid (DHF) plant.
The commissioning follows the approval of the trial production quality by one of India's major solar energy producers, confirming that the product meets their stringent quality requirements, the company said in a statement.
This milestone marks TANFAC as the first Indian chemical company to commission a Solar Grade DHF plant, a critical raw material for the solar energy industry. The company is currently implementing the second phase of the project, which aims to expand the total Solar Grade DHF capacity to 10,000 TPA. This expansion is expected to be commissioned within the next three months.
Commenting on the development, Afzal Malkani, Director, TANFAC, said, “We are excited to announce the successful commissioning of our 5,000 TPA Solar Grade DHF plant after meeting the stringent quality requirements of one of our major solar energy customers. Being the first chemical company in India to achieve this is a significant milestone in TANFAC's history. This development not only strengthens our position in the solar chemicals sector but also has the potential to significantly enhance both our top-line and bottom-line growth. We are equally enthusiastic about the ongoing second phase of the project, which will double our capacity to 10,000 TPA and further reinforce our commitment to supporting India's renewable energy ambitions.”
Tanfac Industries is a joint sector company promoted by Anupam Rasayan India and Tamil Nadu Industrial Development Corporation (TIDCO) and is a major producer of Hydrofluoric Acid and its derivatives. The manufacturing facilities are spread over 60 acres in the chemical complex of SIPCOT Industrial Estate, Cuddalore.
