TECHNICAL SPECIFICATIONSIMPREGNATION 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.- Pre-heating the jobs in either Impregnation Chamber or Oven.
- 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.
- Induction of impregnant (Varnish) in the Impregnation Chamber from impregnant Tank to submerge
- the jobs in it.
- Pressurize the Impregnation Chamber with dry air or nitrogen to fill the voids with impregnant.
- Return the varnish to impregnant Tank.
- Evacuate the Impregnation Chamber and cure the jobs either in impregnation Chamber or in
- Oven for specific time.
