Dried out screw vacuum pumps operate with two screw rotors rotating in Screw Vacuum Pump 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 style results in lower electric energy consumption in comparison to standard screw styles. It also results in a lesser heat load of the compressed gas.
Cooling can be achieved through a higher performance air cooling technique eliminating the necessity of cooling water or indirect cooling technique resulting in uniform temperatures throughout the pump body, eliminating cold spots and offering a thermally stable drinking water jacket. The advanced screw design allows for 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.
