NTP conditions confirming to BS 5000/ IS 13364 (part-II) 1992 to be coupled directly to the Diesel engine and test certificate (Make: Kirloskar/ Crompton/ Greaves/ Equivlent.) 3.ACOUSTIC ENCLOSURE:- Acoustic enclosure shall be powder coated and fabricated of 16 SWG CRCA MS sheet.The silent canopy shall be of nut bolt type construction. Critical processes of punching are done on CNC Machine to maintain dimensional accuracy of hole

within 0.1mm Powder coating done after seven – tank surface preparation process of sheet metal. Canopy panel and doors shall have inside lining of FIRE RETARDANT 64 Kg/m density mineral wool of 100mm thickness as Acoustic material. Four hinged doors shall be provided to canopy. The average sound level at 1 Mt distance shall be less than 75 DBA average or as per CPCB norms. Surface treatment – Painting: The enclosure surface shall be suitably treated for degreasing de-rusting and posphating. The canopies are passed through seven – tank treatment thoroughly. Additional features of canopies: Canopy fabricated on CNC machines with dimensional accuracy of 0.1 mm so as to increase its durability.

Special designed supporting rips/structures are used in canopies so as to give sturdiness and to reduce the vibrations of the DG sets if any World class Cooling package: Canopies shall have cooling package for which it can also perform at 45 degree C/ambient temperature.No grouting required on the ground, only a level surface capable of with standing the DG weight.Lifting hooks shall be provided for the acoustic enclosure, which should be unloaded independently of the DG set. 1150.00 30250.00 The Gen set frame shall also be provided with hooks for unloading Temperature rise inside the canopy: Canopies shall be designed so as to maintain the temperature difference between ambient and air inlet at cleaner within the enclosure well within 5-7 deg centigrade. 4. FUEL TANK : 165 liters. Removable fuel tank shall be fabricated out of 14 SWG CRCA MS sheet and is part of base frame. It is duly

pa inted and fitted with inlet and outlet connection and mechanical uel gauge. Fuel tank can be easily removed for clearing or any maintenance. 5. BASE FRAME : The base frame should be fabricated in sheet metal. The base frame is rugged in construction and designed for mounting engine and brush less alternator closely coupled, with cross members mounted on AVM. The base frame shall be have provision for mounting of acoustic enclosure on it. The supply of generator set includes loading. Unloading and transportation charges. 6. Battery: 2 Nos 12V 180AHR Battery (Ashok Leyland/Cummins/Kirloskar or Equivalent) 7.
