Dry screw vacuum pumps operate with two screw rotors rotating in reverse directions. This traps the moderate to become pumped between your 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 high temperature load of the compressed gas.
Cooling can be achieved through a higher performance air cooling Screw Vacuum Pump method eliminating the need of cooling drinking water or indirect cooling method leading to uniform temperatures throughout the pump body, eliminating chilly spots and providing a thermally stable water jacket. The advanced screw design permits best-in-class hydrogen pumping capabilities. Water cooling may take place in form of both direct drinking water cooling or radiator cooling with air-cooled heat exchangers.
