Dry screw vacuum pumps operate with two screw rotors rotating in opposite directions. This traps the moderate to be pumped between your cylinder and the screw chambers and transports it to the gas discharge. The advanced screw style results in lower electrical energy consumption in comparison to standard screw styles. It also results in a lesser temperature load of the compressed gas.

Cooling may be accomplished through a higher performance air cooling technique eliminating the need of cooling drinking water or indirect cooling method resulting in uniform temperatures through the entire pump body, eliminating cool spots and offering a thermally stable water Screw Vacuum Pump jacket. The advanced screw design allows for best-in-class hydrogen pumping capabilities. Water cooling can take place in kind of both direct water cooling or radiator cooling with air-cooled temperature exchangers.
