New vacuum pump ECODRY 25 and 35 plus – compact, ergonomic, energy-efficient

Leybold expands its ECODRY plus product family of dry
multi-stage Roots vacuum pumps for laboratory, research and development and
analytical applications. The current ECODRY 40 and 65 plus models are now
joined by the new, 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
A characteristic of ECODRY plus, which is particularly important in research facilities and in
analytical laboratories, is its low noise level. "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, naming another
important feature. Thanks to technical optimizations, 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
Above all, the new ECODRY 25 and 35 plus are particularly quiet, with a noise level of 52
dB(A). "A normal conversation is at a noise level of about 55 dB(A)," says Alexander 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," Kaiser explains.
Clean operation
A further advantage of the new ECODRY 25 and 35 plus: it emits neither oil vapor, nor particles.
This is particularly 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 200-240 Volt for
Europe and Asia and 120 Volt 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 energyefficient.
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
This means that ECODRY plus does not simply run through, but achieves exactly the required
performance level. In addition, the ECODRY 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.
