Adhering to this, RECD to be ‘Type Tested’ for an equivalent kVA family as per the System and Procedure from any one of the four Central Pollution Control Board, Govt of India, recognized/approved test agencies/laboratories as given below: (a) Automotive Research Association of India (ARAI, Pune) (b) International Centre for Automotive Testing (ICAT, Manesar) (c) Indian Institute of Petroleum (IIP, Dehradun) (d) Vehicle Research Development Establishment (VRDE, Ahmednagar) Note: 1. Necessary foundation for fixing of RECD as recommended by the OEM is deemed to be included in the quoted rate. 2. The Contractor has to get approved the Make, Technology and Drawings by the GE before commencement of the work. 3. The contractor has to submit the documents all as specified in the PS. 4. Necessary pipes, fittings and fixtures for the installation of RECD is deemed to be included in the quoted rate.

Item no. 1.00 contd... General Technical Requirements (GTR) / Commissioning :- a) Retrofit emission Control device shall be complete with safety precautions to ensure no damage should be done to the DG set operations under any circumstances. The Emission Control retrofit device should be closely coupled with the DG exhaust to ensure 100% of the exhaust passes through the Emission Control retrofit device. b) Anti-Vibration mountings shall be provided for complete Emission Control retrofit device in case of flexible coupling with the diesel generator exhaust. c) Emission Control retrofit device should have protection against under voltage, over voltage, under frequency, over frequency, low battery voltage, over current, earth-fault, short circuit, phase sequence change, etc. d) The Emission Control retrofit device shall be with corrosion resistive and HR paint. e) The Contractor shall provide the trial run (Testing) of retrofit Emission Control device alongwith trial run with the available electrical load at site. The trial run shall be for TWO hours. The electrical loading shall not be more than the rated capacity of the DG set. f) Exhaust piping, extra civil work, distribution board as per the OEM recommendations is deemed to be included in the quoted rate.
