Most pumps in the 600 m3 / h class require in a typical furnace operating pressure below 1 mbar an output of approximately 10 kW. Here, the screw pumps of the DRYVAC series of Oerlikon Leybold Vacuum achieved a much lower energy balance in with a reliable performance, due to an optimized rotor design, an innovative drive concept and the installation of a perfectly adapted frequency converter.
The power consumption of DRYVAC DV650 sets new standards for energy consumption of backing pumps and amounts to only 6.9 kW at 1 mbar and is therefore even below that of a comparable rotary vane pump. The built-in frequency converter offers additional energy savings.
