1 REQUEST FOR INFORMATION ON ENVIRONMENTAL CONTROL (EC) WITH AUXILIARY POWER UNIT (APU) IN TANK T The Indian Army is in the process of upgrading T-72 tank fleet with Environmental Control (EC) with Auxiliary Power Unit (APU). 2. A large fleet of T-72 tanks would require to be fitted with Environmental Control with APU and hence the information may be specifically provided in the reply to the request for information (RFI):- (a) Original Equipment Manufacturer (OEM) status of the equipment. (b) Names of the firms (if any) that have been authorized by the OEM to deal with the Indian MoD. Willingness of the firm to provide the equipment for trials on No Cost No Commitment basis. (d) Level of technology that the firm would be willing to transfer to a firm that will be nominated by Indian MoD. (e) Willingness of the firm to accept the offset clauses as enshrined in the DPP (f) Willingness of the firm to participate in the procurement process in accordance with DPP 2008/amendment to the DPP 2008 issued from time to time. 3. A questionnaire giving specific inputs for the proposed upgradation is given in Appendix A and in addition a Performa to be filled by the vendors is attached as Appendix B. 4. You are requested to respond to this RFI within one month from the date of placing the same on the Website.

2 Appendix A (Ref RFI for Environmental Control (EC) with Auxiliary Power Unit (APU) for tank T- 72) PHYSICAL CHARACTERISTICS 1. Is the environmental control system with APU an integrated and compact system? 2. Can the main assemblies of APU, heat exchangers and pump etc be placed in the present location of SPTA/assembly box outside the tank with only the cooling units and ducts inside the air compartment to direct cool air at entire crew station viz driver, gunner and commander and electronic systems/subsystem in the vicinity. 3.
