TECHNICAL SPECIFICATIONS

IMPREGNATION CYCLE Vacuum / Pressure Impregnation Plant is designed for varnish impregnation to be carried out in following steps and will be generally as per the schematic diagram attached. 1.  Pre-heating the jobs in either Impregnation Chamber or Oven.   2.  Evacuation of Impregnation Chamber (after putting the jobs) to make the voids in the jobs clear       and drying of jobs for specific time & required temperature / vacuum.   3.  Induction of impregnant (Varnish) in the Impregnation Chamber from impregnant Tank to submerge      the jobs in it. 4.  Pressurize the Impregnation Chamber with dry air or nitrogen to fill the voids with impregnant.   5.  Return the varnish to impregnant Tank. 6.  Evacuate the Impregnation Chamber and cure the jobs either in impregnation Chamber or in       Oven for specific time.  MAJOR COMPONENTS IMPREGNATION CHAMBER · Working Volume: 100 Ltrs to 5000 Ltrs.  · Material of construction: M.S. plates, bars, structural etc.  · Working Pressure: @ 4 kg/ cm2 & Vacuum: As per process requirement.  · Lid Opening: Screw Davit type for quick opening & closing.  · Chamber Dimensions: as per job Size and Quantity.  · Will be provided with: Oil Heating / cooling Jacket, Quick Clamping bolts, Stirrer, Neoprene Gaskets,    Sight glass, Illuminating Lamp, Pressure Safety Valve, Vacuum & Pressure gauges etc. as per the    varnish specifications.   IMPREGNANT STORAGE TANK ¨ Material of Construction: M.S. plates, bars, structural etc.  ¨ Will be provided with: Level Indicator, Motorised Stirrer, Thermometer & Thermostat to control the    varnish temperature, Return Line Filter to prevent entry of impurities carried away from impregnation    chamber to storage tank and suitable drain.
