Dry screw vacuum pumps operate with two screw rotors rotating in opposing directions. This traps the moderate to become pumped between the cylinder and the screw chambers and transports it to the gas discharge. The advanced screw design results in lower electric energy consumption in comparison to standard screw styles. In addition, it results in a lower warmth load of the compressed gas.

Screw Vacuum Pump Cooling can be achieved through a high performance air cooling method eliminating the necessity of cooling drinking water or indirect cooling method leading to uniform temperatures through the entire pump body, eliminating frosty spots and providing a thermally stable water jacket. The advanced screw design permits best-in-class hydrogen pumping features. Water cooling may take place in type of both direct water cooling or radiator cooling with air-cooled heat exchangers.
