Leybold offers new ECODRY vacuum pumps

Leybold expands its ECODRY plus product family of dry multi-stage Roots vacuum pumps for laboratory, research and development and analytical applications. Joining the ECODRY 40 and 65 plus models are the latest smaller pump sizes ECODRY 25 and 35 plus. Leybold thus completes its range of quiet, low-maintenance and economical fore-vacuum pumps and fills the gap between SCROLLVAC 18 plus and ECODRY 40 plus.

Ergonomic advantages

"Customers have already appreciated the existing models for this ergonomic advantage. The new ECODRY 25 and 35 plus also have a particularly compact design," says product manager Alexander Kaiser. Thanks to technical optimisations, the vacuum pumps are smaller and more energy-efficient than competitive products. "As a result, we achieve very high pumping speeds with relatively little footprint, which means that a chamber can be evacuated more quickly and a lower ultimate pressure is achieved," summarizes Kaiser.

Pleasant background noise

The new ECODRY 25 and 35 plus are particularly quiet, with a noise level of 52 dB(A). This is important in research facilities and in analytical laboratories. "A normal conversation is at a noise level of about 55 dB(A)," says Kaiser. So it's easy to stay close to the pump and have a normal conversation with the pump noise just fading into the background."

Clean operation

The ECODRY 25 and 35 plus do not emit oil vapor or particles. This is important in research institutes and laboratories where a clean working environment is essential. The oil-free multi-stage Roots pumps ECODRY 25 and 35 plus also have a maintenance interval of five years, during which time they run without any servicing. No oil to check and change so users can devote themselves fully to their research and laboratory work.

Pressure gauge optimizes energy consumption

While the ECODRY 40 and 65 plus are still available in the two voltage variants 200-240V for Europe and Asia and 120V for North America, there is only one variant required for each of the new ECODRY 25 and 35 plus worldwide. Equipped with an integrated pump controller, they are suitable for all voltage ranges. Customers also have the option of connecting a pressure gauge directly to the vacuum pump. "This integration is interesting because it allows the pump performance to be adapted again specifically to the respective requirement," explains Product Manager Kaiser. With the help of the gauge, the pump determines the pressure: If this is low enough, the pump can reduce its speed and becomes even quieter and more energy- efficient. What's more, the ECODRY plus is emitting less heat, which means the air conditioning system has less work to do.

Various interfaces for the smart laboratory

The ECODRY plus does not simply run through, but achieves the required performance level. It  has connections for easy integration of the pump into external control systems and for reading all data from other systems. With its various interfaces such as USB and RS485 as well as the new intuitive LEYASSIST software, the new ECODRY 25 and 35 plus is thus ideally equipped for all sustainable, future-proof industrial 4.0 applications.
