Dry screw vacuum pumping system in vacuum / Pressure impregnation process

Vacuum Pressure Impregnation (VPI) is a process that uses vacuum and pressure to seal porous materials with varnish or resin. The process is used primarilyto fill gaps in materials to create a void free insulation in various devices.

Dry screw vacuum pumping system in squalene distillation from fish oil

Squalane, a saturated hydrocarbon (C30H62), is obtained by hydrogenation of squalene, which have been used as cosmetics for moisturizer. At present, squalane is used as cosmetics, medicines and sometimes used with fibers.

Oleoresins & curcumin extraction from turmeric rhizome under vacuum

Curcumin is extracted from the dried root of the rhizome Curcuma Longa (Turmeric). The process of extraction requires the raw material to be ground into powder, and washed with a suitable solvent that selectively extracts coloring matter.

Dry screw vacuum pumping system in industrial effluent treatment process based on evaporation technology.

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase after reaching its boiling point.

Dry screw vacuum pumping system in current and potential transformer drying and degassing

The presence of moisture in the transformer, to whatever degree, does actual harm to insulation which is, in fact permanent damage. Drying methods only substantially reduce that deterioration.

Dry screw vacuum pumping system in biodiesel production

Biodiesel is simply a liquid fuel derived from vegetable oils and fats, which has similar combustion properties to regular petroleum diesel fuel.
