Dry screw vacuum pumps operate with two screw rotors rotating in opposite 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 style results in lower electrical energy consumption compared to standard screw styles. In addition, it results in a lesser heat load of the compressed gas.
Cooling can be achieved through a higher performance air cooling method eliminating the necessity of cooling drinking water or indirect cooling method resulting in uniform temperatures through the entire pump body, eliminating chilly spots and providing a thermally stable drinking water jacket. The advanced screw design allows for best-in-class hydrogen pumping capabilities. Water cooling may take place in type of both direct water cooling or radiator cooling with air-cooled temperature exchangers.
