Dry screw vacuum pumps operate with two screw rotors rotating in reverse Screw Vacuum Pump 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 heat load of the compressed gas.
Cooling may be accomplished through a higher performance air cooling method eliminating the need of cooling drinking water or indirect cooling technique leading to uniform temperatures throughout the pump body, eliminating chilly spots and providing a thermally stable water jacket. The advanced screw design allows for best-in-class hydrogen pumping capabilities. Water cooling may take place in form of both direct water cooling or radiator cooling with air-cooled warmth exchangers.
