Dry screw vacuum pumps operate with two screw rotors rotating in opposing directions. This traps the Screw Vacuum Pump 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 electrical energy consumption in comparison to standard screw designs. In addition, it results in a lower temperature load of the compressed gas.
Cooling may be accomplished through a high performance air cooling method eliminating the need of cooling drinking water or indirect cooling technique leading to uniform temperatures throughout the pump body, eliminating cool spots and offering a thermally stable water coat. The advanced screw style allows for best-in-class hydrogen pumping capabilities. Water cooling can take place in form of both direct water cooling or radiator cooling with air-cooled warmth exchangers.
