Other Details

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.

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:

    Chamber Dimensions: Diameter ---mm, Height ---- mm (suitable for jobs)
    Material of Construction: MS plates, bars and structural
    Working Pressure: 1- 4 kg /cm2
    Vacuum: 0.1 / 1 / 10 / 50 torr
    Lid Opening: Screw Davit type for quick opening & closing or hydraulic operated automatic
    Temperature Control: With thermostat or digital TIC
    Provided With: Oil heating, cooling jacket, quick clamping bolts, stirrer, neoprene gaskets, sight glass, illuminating lamp, pressure safety valve, vacuum and pressure gauges as per the varnish specifications

Impregnant Storage Tank:

    Material of Construction: M.S. plates, bars and structural
    Varnish Tank Capacity: 50 - 80% of impregnation chamber
    Will be provided with level indicator, motorized stirrer and TIC to indicate and control the varnish temperature. Return line filter to prevent entry of impurities carried away from impregnation chamber to storage tank and suitable drain. Silica gel breather will also be provided to prevent absorption of atmospheric moisture

Compressor:

    Type: Piston type
    Free Air Displacement: 10 CFM
    Working Pressure: 4 Kgf/cm2
    Make: Reputed make in case of low vacuum, pressure impregnation, combined vacuum, pressure pump can be used

Impregnant Transfer System:

    Interconnecting Pipes: M.S. ERW, B Class or SS in case of resin impregnation
    Valves: Piston type (Vacuum tight with O' rings & Nylon wipers) OR ball valves with teflon seals (manual or actuated)
    Connections: Flanged type with Neoprene O' rings
    Operating Platform: M.S. fabricated suitable for easy plant operation in case of big plants

Control Panel:

For easy and safe operation, centralized control panel will be provided along with necessary gauges and controls.
