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.
A characteristic of ECODRY plus, which is particularly important in research facilities and in analytical laboratories, is its low noise level of 52 dB(A). The new ECODRY 25 and 35 plus also have a particularly compact design. Thanks to technical optimizations, the vacuum pumps are smaller and more energy efficient. The ECODRY 25 and 35 plus emit 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 work.
While the bigger versions 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. 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. 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 25 and 35 plus are equipped for all sustainable, future-proof industrial 4.0 applications.
