4.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 Machines to maintain dimensional accuracy of hole within 0.1 mm. Powder coating done after seven-tank surface preparation process of sheet metal. Canopy panel and doors shall have inside lining of FIRE RETARDANT 64Kg/m density Mineral wool of 100mm Thickness as acoustic material. Four hinged doors shall be provided to canapy. The average sound level at 1Mt. 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 degreasing and posphating. The canapy are passed through seven- tank treatment thoroughly. Additional features of Canopies: Canopy fabricated on CNC machines dimensional Accuracy of 0.1mm 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 deg c/ ambient temperature No grouting required on the ground only a level surface capable of withstanding the ground, only a level surface capable of withstanding the DG weight.

Lifting hooks shall be provided for the acoustic Enclosure, which should be unloaded independently of the DG Set. 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 air cleaner within 5-7 deg centigrade. 6.FUEL TANK: 460Ltrs. Removable fuel tank shall be fabricated out of 14SWG CRCA MS sheet and is part of base frame. It is duty painted and fitted with inlet and outlet connections and mechanical fuel gauge. Fuel tank can be easily removed for cleaning or any maintenance. 7.BATTERY: 2 Nos 12 V 180 AHR battery. With 12 V, 15a Output Battery Charger with Boost and Trickle charge facility. The Generator Set Should be erected on the existing generator bed with all precaution testing and commissionning the Generator with load running for 8hours with intial charging. the tes certificate and the warranty certificate should be issued at the time of commissioning.
