Dried out screw vacuum pumps operate with two screw rotors rotating in reverse directions. This traps the Screw Vacuum Pump medium to be 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 compared to standard screw designs. It also results in a lower high temperature load of the compressed gas.

Cooling may be accomplished through a high performance air cooling technique eliminating the necessity of cooling water or indirect cooling technique resulting in uniform temperatures through the entire pump body, eliminating cold spots and offering a thermally stable water jacket. The advanced screw design permits best-in-class hydrogen pumping capabilities. Water cooling may take place in type of both direct drinking water cooling or radiator cooling with air-cooled temperature exchangers.
