where chamber pumpdown time is important. The responsive inverter control and special configuration
enables even faster chamber pumpdown with optimal energy efficiency.
WWhilst the standard EOSi pumps are able to reliably
pump water vapour loads similar to equivalent rotary vane pumps, the W version is designed to pump
significantly higher water vapour loads and can off er superior comparative performance where required on
applications such as pipeline drying and freeze drying.
