SD Technical Services has proudly served the Indian Army by manufacturing the complete compressed air system for the T-72 and T-90 main battle tanks and the BMP-1 and BMP-2 armoured personel carriers since 1992. The highlights of the systems are a working pressure of 150 Bar and an emphasis on metal to metal pneumatic sealing for critical valves. The following codes are supplied by us to the ordinance factories and customers such as BEML through our subsidiary Xena Fluid Systems.
