Dry screw vacuum pumps operate with two screw rotors rotating in Screw Vacuum Pump opposite directions. This traps the 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 electrical energy consumption in comparison to standard screw designs. In addition, it results in a lower temperature load of the compressed gas.
Cooling can be achieved 
through a high performance air cooling method eliminating the need of cooling water or indirect cooling technique leading to uniform temperatures through the entire pump body, eliminating frosty spots and offering a thermally stable water jacket. The advanced screw design permits best-in-class hydrogen pumping features. Water cooling may take place in type of both direct water cooling or radiator cooling with air-cooled temperature exchangers.
