High Vacuum Impregnation Plant
High Vacuum Impregnation Plant
We are one of the reputed manufacturers of high vacuum impregnation plant that has gained wide appreciation for operational fluency and longer service life. This vacuum, pressure impregnation plant is designed for varnish impregnation to be carried out in efficient manner. For precision functioning, the plant is provided with impregnation chamber, impregnant storage tank, vacuum system, compressor, impregnant transfer system and control panel.
Technical Specifications:
Given below are the steps to be followed:
Pre-heating the jobs in either impregnation chamber or in oven depending upon the time available
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
Cure the jobs either in impregnation chamber or in oven for specific time if time available is less
The plant is provided with the following major components:
Impregnation chamber:
