See specificationsThe highest grade a manufacturer can earn in India's Zero Defect Zero Effect (ZED) programme. This certificate covers our two manufacturing sites in Coimbatore.
The letters ZED stand for Zero Defect, Zero Effect, meaning defect-free products made without harming the environment. India's Ministry of MSME operates the scheme jointly with the Quality Council of India, whose assessors rate a plant against many parameters including process control, quality, energy, safety and waste. Of the three tiers (Bronze, Silver and Gold), Gold is the highest, and we are proud to have achieved it.
International purchasers buying equipment from India are placing growing weight on independently verified evidence of quality and responsible manufacturing. Because the Quality Council of India carries out the ZED assessment, it adds a further government-backed layer of assurance about the plant that will build your equipment.
