Dried out screw vacuum pumps operate with two screw rotors Screw Vacuum Pump rotating in reverse directions. This traps the moderate to end up being pumped between the cylinder and the screw chambers and transports it to the gas discharge. The advanced screw design results in lower electric energy consumption in comparison to standard screw designs. It also results in a lesser temperature load of the compressed gas.
Cooling may be accomplished through a high performance air cooling technique eliminating the need of cooling water or indirect cooling technique resulting in uniform temperatures through the entire pump body, eliminating frosty spots and providing a thermally stable drinking water coat. The advanced screw style allows for best-in-class hydrogen pumping features. Water cooling can take place in form of both direct drinking water cooling or radiator cooling with air-cooled high temperature exchangers.
