Dried out screw vacuum pumps operate with two screw rotors rotating in reverse directions. This traps the Screw Vacuum Pump medium to become pumped between your cylinder and the screw chambers and transports it to the gas discharge. The advanced screw style 
results in lower electric energy consumption in comparison to standard screw designs. It also results in a lower warmth load of the compressed gas.
Cooling can be achieved through a higher performance air cooling method eliminating the need of cooling water or indirect cooling method resulting in uniform temperatures through the entire pump body, eliminating cold spots and offering a thermally stable drinking water jacket. The advanced screw design permits best-in-class hydrogen pumping features. Water cooling may take place in kind of both direct drinking water cooling or radiator cooling with air-cooled high temperature exchangers.
