Our quality systems are independent of production & base of our work ethic.
All International routine & type tests like Air Pressure Test, Vibration Test, Pressure Impulse Test, Internal & External Corrosion Test, Wind Tunnel Test are conducted on our radiators as per the BIS / A STM / JIS standards,
Stringent quality checks right from the receipt of raw material to final inspection of the finished goods are conducted regularly. Quality audit at predetermined intervals is the norm. We are Bureau Veritas certified ISO: 9001:2000 Company.
