Dry screw vacuum pumps operate with two screw rotors rotating in reverse 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 compared to standard screw designs. It also results in a lesser temperature load of the compressed gas.
Cooling may be accomplished through a higher Screw Vacuum Pump performance air cooling technique eliminating the need of cooling water or indirect cooling method leading to uniform temperatures throughout the pump body, eliminating cold spots and providing a thermally stable drinking water coat. The advanced screw design permits best-in-class hydrogen pumping capabilities. Water cooling can take place 
in kind of both direct drinking water cooling or radiator cooling with air-cooled warmth exchangers.
