The process is mainly the use of one or several gaseous compounds or elements containing film elements, chemical reaction on the surface of the substrate to produce a film method.

Applicable products: Roots vacuum unit, dry screw vacuum pump, rotary vane vacuum pump, scroll pump, molecular pump and other pumps.

The process is to separate two or more layers or parts with different temperatures, pressures, compositions and phase states, while the negative pressure state can reduce the boiling point of the material and save heating costs.

Applicable products: Roots vacuum unit, dry screw vacuum pump, rotary vane vacuum pump and other pumps.

The process is to reduce or oxidize biological products by increasing the vacuum degree to reduce the boiling point of the material, evaporating the liquid from the solid, so that the biological components or active ingredients are not destroyed.

Applicable products: Roots vacuum unit, dry screw vacuum pump, liquid ring vacuum pump and other pumps.

The process is to use the force generated by the pressure difference between the vacuum and the atmosphere to transport materials, forming the gas flow in the pipeline, driving the movement of powdery materials, so as to complete the transportation of powder.

Applicable products: Roots vacuum unit, dry screw vacuum pump, rotary vane vacuum pump and other pumps.

The process is to evaporate and cool the excessive saturated liquid to form a crystal, so that the evaporation and cooling rate can be controlled by adjusting the pressure, and the cost can be reduced by reducing the boiling point of the liquid.

Applicable products: Roots vacuum unit, dry screw vacuum pump, rotary vane vacuum pump and other pumps.
